5. E-textiles¶
This week we are learning about the relation between textiles and electronics with an introduction to soft circuit and smart fabrics. It was a challenge for me as I haven't tried embeding electronics on a garment and I didn't know many things about electronics! Liza Stark presented a lectured that help us a lot to understand about creating a circuit, conductive materials, switches etc.
We had to create two switches:
1) a break digital (0/off or 1/on) results
2) sensor resistance manipulation with analog (range of value) results.

Research¶
Conductive Materials - Fabrics: Copper, eeontex conductive fabric, ESD foam...
-
Threads and yarns: Elitex, Karl Grimm, Bekinox, Adafruit Stainless Steel, Silverspun yarn...
-
Inks and tapes: CuPro- Cote by Less EMF, copper tape, bare conductive, copper foil sheet, conductive fabric tape, circuit scribe... Great Source of information about conductive materials Kobakant
a useful tutorial to understand better the electricity and sensors by Emma Pareschi
Digital Sensor¶
Materials: Conductive tape, neoprene, non-conductive foam
In class, we made some tests on creating digital sensors
Citlali taught us to use the XIAO - ESP32C3 to digital and analog read and write.
The XIAO is a mini computer that we then used to talk to the components and connect the inputs to outputs with a way for us to read it as well. - Code
int buttonState;
void setup() {
Serial.begin(9600);
pinMode(D7,INPUT); // Enable the internal pull-up resistor
}
void loop() {
buttonState=digitalRead(D7);
Serial.println(buttonState);
}
References & Inspiration¶
Moodboard
For this assignment, I wanted to create accessories that work as sensors
Workflow¶
I wanted to create something simple and easy in order to understand better how both sensors work.
following the example of Shemakes Interactive Monsters I created my own design
Materials
- Velostat (most common used) – carbon-impregnated black polyethylene film. Conductivity with this material is not affected by humidity or ageing
- Conductive tape
- LED RGB
- COIN Battery
- Eeontex Polysense
Analog Sensor¶
following the example of Kobakant
I wanted to create a Time Sensing Bracelet
