12. Skin Electronics¶
Research & References¶
I set out to develop conductive body paint designed specifically for use with skin electronics. My goal was to create a material that could be safely applied to the skin while maintaining the ability to conduct electricity effectively. This paint would serve as a versatile medium for connecting electronic components directly to the body, enabling innovative applications in wearable technology and interactive designs.
The conductive body paint would need to be formulated with skin-safe materials, ensuring it could be worn comfortably and without irritation. Additionally, it would require a high level of conductivity to establish reliable connections between electronic elements, such as sensors, circuits, or LEDs, while remaining flexible enough to adapt to the movement of the skin.
This project aimed to combine functionality and creativity, paving the way for new possibilities in wearable technology, artistic expression, and bio-integrated electronics. By exploring this concept, I hoped to push the boundaries of what can be achieved in the intersection of technology, art, and human interaction.

The Recipe I Used – Version 1¶
For the initial version of the conductive body paint, I began by researching recipes online and came across a promising formula provided by the Clean Energy Institute. Using this as a foundation, I experimented with four different variations to test the effectiveness and versatility of the paint under various conditions. Each version incorporated a different binding agent, allowing me to compare their properties and suitability for use on the skin.
The four binding agents I tested were:
- Glue Stick – Chosen for its easy application and quick-drying properties.
- Acrylic Glaze – Selected for its smooth texture and potential to create a flexible finish.
- Mod Podge – Known for its adhesive and sealing qualities, which could enhance the paint's durability.
- Heavy Body Acrylic Paint – Used for its thick consistency, offering a more robust and opaque coating.
Each recipe was carefully mixed and evaluated for factors such as conductivity, adhesion to the skin, flexibility, and overall performance. This iterative process allowed me to explore how different materials interact with the conductive elements and how they perform when applied to the skin. The goal was to identify the most effective combination that balances conductivity, comfort, and practicality for use in skin electronics.
notes
- I followed the instructions provided on the website very carefully, paying special attention to the guidelines for heating the glue. The directions didnt emphasized that the glue should never be microwaved for more than five seconds at a time. Unfortunately, I learned this through firsthand experience when I tried heating it for a full ten seconds and ended up burning my very first glue stick. The website said it should be microwaved for a minute. It’s also worth noting that the glue is highly flammable, making it even more important to proceed with caution. By adhering strictly to these short, controlled heating intervals, I was able to ensure a safer and more effective melting process for the project

Conductivity Test for Recipe 1¶
To evaluate the performance of the first version of the conductive body paint, I conducted a series of tests to assess its conductivity and usability. For consistency, I used a stencil to apply the paint, ensuring that all test shapes were uniform in size and thickness. This standardized application process allowed for accurate comparisons across different test scenarios. A paintbrush was used to carefully apply the paint within the stencil, ensuring even coverage.
The test was performed on two individuals to gather diverse data:
- Test Subject 1: A male participant.
- Test Subject 2: A female participant.
Both subjects were instructed to remain still during the application and drying process to minimize variations caused by movement. Once the paint was fully dry, I proceeded to test its conductivity by connecting it to a multimeter. The results of the test, along with observations on adhesion, flexibility, and overall performance, provided valuable insights into the effectiveness of the recipe.
Below are the detailed results from the tests:
| Test Subject 1 A male participant. | Description | Conductivity |

| 1 Recipess - Acrylic paint | 1692 ohm Ω |
These findings will inform further refinements to the formula, helping to identify areas for improvement in subsequent versions.

The Altered Recipe – Version 2¶
After testing the original recipe, I realized that it required modifications to improve its performance. One of the main issues with the initial formula was the lack of sufficient graphite powder, which significantly affected the paint's conductivity. Since graphite is a key component responsible for the conductive properties, the original amount proved inadequate for establishing reliable connections.
To address this issue, I doubled the quantity of graphite powder in the recipe. By increasing the graphite content, I aimed to enhance the conductivity of the paint, ensuring it could effectively transmit electrical signals when used with skin electronics. This adjustment was critical for achieving a more functional and efficient product.
Version 2 of the recipe was a step forward in optimizing the balance between the binding agent and the conductive material. By focusing on the paint’s conductivity, I made significant progress toward creating a formula that meets the practical requirements of wearable and skin-applied electronics. This alteration underscored the importance of testing and iteration in refining the recipe for better results.

Conductivity Test for Recipe 2¶
To evaluate the performance and effectiveness of the second version of the conductive body paint, I conducted a detailed series of tests focusing on its conductivity, adhesion, flexibility, and overall usability. This testing process was designed to provide consistent and reliable data, which would guide further refinements to the formula.
Application Method¶
For accuracy and consistency, I used a stencil to apply the paint, ensuring that all test shapes were uniform in size and thickness. This method eliminated variations that could affect the results, allowing for a more controlled assessment. A fine paintbrush was used to carefully fill in the stencil, ensuring an even application of the paint across all samples.
Test Participants¶
The paint was tested on two individuals to account for variations in skin type and texture, providing a broader range of data:
- Test Subject 1: Male participant.
- Test Subject 2: Female participant.
Both participants were instructed to remain as still as possible during the application and drying phases to minimize any inconsistencies caused by movement. The drying time was carefully monitored to ensure the paint reached a fully set state before conductivity testing began.
Conductivity Testing¶
Once the paint had dried completely, I used a multimeter to measure its conductivity. The multimeter was connected to the painted area to test the resistance and verify the effectiveness of the conductive pathway. The data collected included numerical resistance values and qualitative observations of how well the paint conducted electricity.
Observations and Results¶
In addition to conductivity, I assessed several other factors during the test:
- Adhesion: How well the paint adhered to the skin after drying.
- Flexibility: Whether the paint maintained its integrity when the skin moved.
- Durability: How resistant the paint was to smudging or peeling with light contact.
These observations, combined with the multimeter readings, provided valuable insights into the performance of Recipe 2. By analyzing this data, I was able to identify areas for improvement in future iterations of the conductive body paint, ensuring better functionality and user experience.
The detailed results and findings from these tests are documented below, forming the basis for further refinement of the recipe.
Conductivity Test After 30 Minutes¶
To assess the effectiveness of the conductive body paint, I performed a conductivity test 30 minutes after the paint was applied and allowed to dry. Using a multimeter, I recorded measurements to evaluate the electrical conductivity of the paint and its ability to maintain a stable connection.
In addition to the conductivity test, I documented the paint’s durability through photographs. These images provided a visual reference for the paint's condition after the initial drying period. Upon reviewing the pictures, I noticed that some of the paint had already begun to crack, even without subjecting the surface to any friction or movement from the skin. This cracking indicated potential issues with the flexibility and adhesion of the paint, which would need to be addressed in future iterations of the formula.
The results from this test highlighted important areas for improvement, particularly in achieving a balance between conductivity, durability, and flexibility. These findings served as valuable feedback for refining the recipe further, guiding adjustments to create a more resilient and reliable conductive body paint for use with skin electronics.
Testing Makeup Primers for Conductivity¶
After observing that some of the conductive body paint formulas struggled to maintain adhesion to the skin during extended use, I decided to experiment with an alternative approach. My idea was to test whether makeup primers, when combined with graphite powder, could create a conductive layer. This method would leverage the adhesive properties of primers commonly used in cosmetics, potentially offering a more practical and skin-safe solution for maintaining conductivity.
I selected two of the strongest primers available in my collection:
- Magic Fix by ArtDeco – This primer is designed for use on lips or eyelids, typically to enhance the adhesion of glitter or other cosmetic products.
- Proof It by NYX – A long-lasting primer formulated for eyelids, known for its ability to hold pigments securely in place.
To conduct the test, I applied each primer to a small area of skin, mimicking the method typically used for makeup application. Once the primer was set, I dusted graphite powder over it in the same manner as applying eyeshadow. The graphite layer was intended to serve as the conductive element, relying on the primer to hold it in place.
This process allowed me to evaluate whether the combination of makeup primers and graphite powder could provide adequate conductivity while maintaining strong adhesion to the skin. It also presented an opportunity to explore a less invasive, cosmetically friendly method for integrating conductive elements into wearable designs. The results of this test would help determine the potential of makeup products as a foundation for skin electronics, combining functionality with aesthetics.
Conductivity Test After 60 Minutes¶
To evaluate the effectiveness of the conductive body paint, I conducted a conductivity test 60 minutes after the paint was applied and allowed to dry. Using a multimeter, I measured the electrical conductivity to determine the paint's ability to establish and maintain a stable connection. This test was crucial for understanding how the paint performed under realistic conditions.
For this test, I also iadded two additional test lines of paint applied over makeup primers on test subject two. These primers were allowed to dry for 30 minutes with graphite powder layered on top. This experiment aimed to explore whether the primers could improve the paint’s adhesion and performance.
In addition to measuring conductivity, I documented the paint's physical condition through photographs taken after the drying period. These images revealed that, in some areas, the paint had already begun to crack significantly and flake off, even without exposure to movement or friction from the skin. This observation highlighted potential weaknesses in the formula, particularly regarding its flexibility and adhesion. These issues would need to be addressed in future versions to ensure that the paint remains durable and functional during use.
Interestingly, the makeup primers showed no conductivity on their own. However, this does not necessarily rule out their potential as a base layer to improve the adhesion of the conductive paint. By creating a more stable surface, the primers might contribute to better overall performance, even if they do not directly enhance conductivity.
The results of this test underscored the importance of balancing conductivity, flexibility, and durability in the paint's formulation. The findings provided valuable insights that will inform future adjustments to the recipe, helping to develop a more resilient and reliable conductive body paint suitable for use with skin electronics.

Skin Condition After Cleaning¶
Both test subjects removed the paint after wearing it for approximately 60 minutes, using only hand soap and a washcloth. The paint washed off with relative ease, leaving no visible residue behind. However, signs of skin irritation began to appear within just a few minutes after removal.
To better understand the progression of these reactions, I documented the condition of their skin at three distinct intervals: immediately after washing, again 15 minutes later, and once more after an additional 15 minutes. In nearly all cases, pronounced irritation was evident, ranging from mild redness to more severe reactions. Test Subject 1, in particular, exhibited noticeably worse symptoms compared to Test Subject 2.
Fortunately, the irritation subsided overnight, and by the following morning, both individuals reported that their skin had returned to its normal condition without any lingering discomfort. Nevertheless, these observations raise important questions about the need for additional precautions. It may be necessary to incorporate a primer, test alternative formulations, or adjust application methods to ensure that the paint can be worn safely and comfortably. Further research and refinements to the formula will be essential to prevent such adverse reactions and ensure a more reliable, skin-friendly product.

The Road So Far – Summary¶
Among the materials tested, acrylic paint consistently performed the best for both subjects and proved to be the most reliable medium overall. Its application resulted in minimal skin reactions, making it a safer choice compared to the other options evaluated. Based on these findings, I plan to revisit the formula, introducing a suitable primer to improve adhesion and potentially enhance the conductivity. Additionally, I will conduct tests using pure graphite alone to determine if the graphite itself is contributing to the skin irritation observed in certain cases.
On the other hand, Mod Podge showed the poorest results. Not only did it fail to maintain reliable conductivity, but it also proved unsuitable for skin contact due to the adverse reactions observed. Consequently, it should be avoided in future formulations for this type of application. By focusing on refining the acrylic-based formula and further investigating the role of graphite, I aim to develop a more effective and comfortable conductive body paint for skin electronics.

The Altered Recipe – Version 3¶
After thoroughly evaluating both the original formula and Version 2, I recognized the need for further refinements to enhance the paint’s overall performance. One of the primary issues with the first recipe was the insufficient amount of graphite powder, which significantly limited its conductive properties. Although Version 2 introduced some improvements, it still presented a major problem: the paint tended to crack and flake as it dried, leading to an unreliable and uncomfortable finish.
To address these challenges, I introduced NIX primer as a preparatory base layer before applying the paint. This primer helped create a more stable surface, ensuring better adhesion and a smoother application. Additionally, I incorporated glue into the mixture to increase its elasticity, allowing the paint to flex with the natural movements of the skin without losing its integrity. This modification was critical in achieving a balance between durability, conductivity, and user comfort.
In Version 3, I focused on optimizing the ratio of binding agents, conductive materials, and additives to produce a more robust and effective product. The goal was to improve the paint’s conductivity while ensuring that it remained flexible, skin-friendly, and long-lasting. To verify that the graphite powder wouldn’t introduce any adverse reactions, I applied a small test patch on the skin. This trial allowed me to determine if the graphite content might cause irritation.
By iterating through these steps, Version 3 represented a significant leap forward in creating a functional, reliable, and comfortable conductive body paint suitable for integrating electronics directly onto the skin’s surface.

Conductivity Test After 30 Minutes¶
To thoroughly assess the performance of the third iteration of my conductive body paint, I conducted a comprehensive test focused on both its electrical properties and its physical durability. Approximately thirty minutes after applying the paint and allowing it to dry, I measured its conductivity using a multimeter. This instrument provided accurate readings of the paint’s electrical characteristics, enabling me to determine how effectively it maintained a stable, continuous connection suitable for skin electronics.
In addition to quantifying its conductivity, I documented the paint’s surface condition by taking a series of photographs. These images offered a valuable visual reference for evaluating changes that occurred during the initial drying and settling period. Upon reviewing the photographs, I noted that certain areas of the paint had already begun to flake. Even more concerning, some sections—particularly those adapted from the acrylic paint used in version 2—were peeling off in sizable patches, while others had developed cracks.
These observations were significant, as they illuminated critical weaknesses in the paint’s formulation. Although the paint displayed a degree of conductivity, the early onset of flaking, peeling, and cracking indicated a lack of proper adhesion and flexibility. The combination of these issues suggested that while the paint could conduct electricity, it failed to provide the durability and resilience needed for practical, long-term use on the human body.
The findings gleaned from this test underscored the importance of achieving a delicate balance among conductivity, durability, and adaptability. As I move forward, these results will guide further refinements to the recipe, including adjustments in binding agents, alterations in ratios of components, and the incorporation of materials that promote better adhesion and elasticity. By addressing these shortcomings, I aim to develop a more robust and reliable conductive body paint—one that not only exhibits strong electrical properties but also endures the stresses of movement and environmental exposure. This iterative process of testing, analyzing, and improving will ultimately bring the project closer to creating a truly effective conductive paint solution for skin electronics.
Conductivity Test After 60 Minutes¶
To thoroughly assess the performance of the conductive body paint, I performed a conductivity test one hour after the paint had been applied and allowed to dry. Using a multimeter, I carefully measured the electrical conductivity to verify whether the paint could maintain a stable and reliable connection under realistic conditions. This evaluation was critical in determining the paint’s potential viability for use in wearable electronic applications.
In addition to measuring its electrical properties, I documented the paint’s physical state by taking a series of photographs at the 60-minute mark. Upon reviewing these images, I observed that large patches of the paint were detaching from the skin’s surface. This issue persisted despite attempts to improve adhesion by incorporating glue into the mixture. While the glue was intended to strengthen the bond between the paint and the skin, it did not yield the desired results.
These findings highlighted a significant challenge in the formulation process. Although the paint demonstrated some level of conductivity, its poor adhesion and durability limited its practical use. These observations informed the need for further experimentation, prompting a reassessment of the recipe and exploration of alternative binding agents that could enhance the paint’s longevity and overall performance.

Skin Condition After Cleaning¶
Upon examining the skin condition after the cleaning process, I observed a substantial improvement compared to the previous version. Applying NIX as a base layer proved effective, as it helped create a protective barrier against any potential irritants. As a result, there were no signs of irritation or discomfort, indicating that the protective layer played a critical role in maintaining skin health.
Additionally, I was able to determine that the graphite powder used in the recipe was not the source of the irritation experienced earlier. This finding was significant because it allowed me to focus on other variables that might be influencing the skin’s reaction. By ruling out graphite powder, I can now direct further experimentation and adjustments toward optimizing the paint’s other components, ensuring that the final formulation remains both safe and effective for application to the skin.

Body Paint as a Conductive Agent with Skin Electronics¶
In my experiments, I explored the use of body paint as a conductive medium to connect electronic components directly on the skin. To achieve this, I employed a LilyPad Coin Cell Battery Holder as the power source for a LilyPad Blue LED, effectively creating a simple circuit applied directly to the arm. By using conductive body paint as the linking material between the battery holder and the LED, I aimed to demonstrate a more flexible and wearable approach to electronic integration.
However, one challenge I encountered was ensuring a sufficient layer of conductive paint to maintain a stable electrical connection. In practice, this meant applying multiple coats of the paint to achieve the desired conductivity and reliability. Although this requirement added complexity to the process, it also underscored the potential of conductive body paint as a customizable, skin-friendly interface for wearable electronics. Through further experimentation and refinement, I hope to develop a formula that requires less paint to achieve the same level of performance, ultimately making this method more practical and user-friendly.
notes
- I plan to conduct a test using a microcircuit in combination with the conductive body paint, but there are a few issues I need to address beforehand. One primary concern is the uneven conductivity observed in the initial trials. To ensure that the microcontroller remains safe and does not experience any damage, it is essential that I resolve these inconsistencies first.
Before moving forward with live electronics, I will carefully refine the paint’s formulation, adjusting its composition to achieve a more uniform conductive surface. This involves experimenting with different ratios of conductive materials, binders, and additives until I achieve a stable and reliable level of conductivity. Only after this stage will I proceed with integrating the microcircuit, thereby reducing the risk of electrical shorts, malfunctions, or potential damage to the sensitive components.
By taking these precautions and ensuring the body paint’s conductivity is consistent and dependable, I can more confidently explore innovative applications of this technology and push the boundaries of wearable electronics.
notes
- During the testing phase, I encountered a significant safety issue while attempting to connect several LEDs to the conductive lines. In the process, I accidentally caused multiple LEDs to burn out, which indicated that the current or voltage levels were not properly managed. Even more alarming was the large spark that occurred when I connected the circuit to the battery pack. This unexpected discharge suggested that there may have been an underlying problem that needed immediate attention.
Such electrical mishaps are not only detrimental to the electronic components but also raise serious safety concerns for anyone who might wear the device. A spark of this nature can lead to unexpected heat, potential burns, or other hazards if not promptly and thoroughly addressed. Before proceeding with further development, it is imperative to identify the root cause of these issues and implement more robust safety measures. Ensuring the reliability and security of the system will be critical to the long-term success of the project and the well-being of its users.

Summary¶
Through the initial stages of experimentation with conductive body paint, several key insights have emerged. One of the primary challenges encountered is achieving the right level of thickness. The paint needs to be sufficiently dense to maintain stable electrical conductivity; however, making it too thick introduces its own set of problems. Excessive thickness not only complicates application but also diminishes the paint’s comfort and usability when applied to the skin.
Another issue is the tendency of the paint to crack over time. To mitigate this, multiple layers have been necessary, but this solution is not ideal. Applying several coats increases both the complexity of the process and the potential discomfort for the wearer. It also raises concerns about how well the paint will adhere and how easily it can be removed.
The findings suggest that the paint formulation requires an elastic component. Incorporating a flexible additive could improve both the stability of the conductivity and the integrity of the applied paint. Such an ingredient might prevent cracking, reduce the need for multiple layers, and create a more skin-friendly consistency. By achieving a better balance between thickness, conductivity, and elasticity, it should be possible to produce a conductive body paint that is both reliable and comfortable to wear.

notes
- Graphite proves to be even more troublesome than glitter, as it has an uncanny ability to cling to every surface it touches. Once released, it spreads rapidly, much like a wildfire that engulfs everything in its path, and is notoriously difficult to remove. The fine particles work their way into every crevice, becoming a persistent presence that requires considerable time and effort to eliminate. This stubborn behavior makes it challenging to maintain a clean and orderly space, often necessitating specialized cleaning techniques or multiple rounds of sweeping and wiping to restore surfaces to their original state.
