9. Wearables

Research

What is the definition of "wearables"? The lecture was fascinating! So many trials have already been done.

The first time I heard the word "wearable" was when I happened to attend a presentation at the company Pearl yacht where I usually purchase embroidery machine threads.

They were showcasing their research with a university using conductive thread. They demonstrated writing characters on a "keypad" embroidered onto pants with conductive thread using a sewing machine. The idea was that you could send messages without having to use your smartphone while walking wearbo is the brand name of these wearable items researched between the university and the thread company.

Wearable items are probably things that are worn on the body and provide functionality by sensing small movements.

References & Inspiration

The three local classes and hands-on experiences I took in Spain:

1- Adrián’s XIAO Lecture

Although it was available online, I learned about XIAO directly from Adrián during my stay in León a week before the lecture.

2- Dani’s Lecture

Coding with Arduino.

I had a LilyPad. During the class, there was a part where we switched from ONBOARD to STRIP, and at first, I didn’t quite get the hang of it! My version was outdated, and I kept getting errors while coding. After about seven attempts, I finally got it! Dani asked me, "You’ve used it before, right?" But honestly, during WEEK05 in León, Adrián and Nuria helped me, so I couldn’t do it on my own. Here, I learned everything from scratch, and I’ll share what I learned with my FabLab members when I return (though they probably already know!).

3- Petra’s Lecture

Silk screen Using the thermo ink.

There is ink that changes color with temperature, so I used it for silk-screen printing. When I heated the silk-screened illustration with an iron... the color changed! From blue to white? Or gray.

Process and workflow

1. Arduino control lightning textile

*Fils: Code of Arduino

2. Thermo ink screen printing & Conductive thred embroidery

Petra demonstrated a silk-screening technique using thermochromic ink. First, applied the ink to a fabric scrap, then embroidered conductive thread over it. When an electric current is passed through the conductive thread, its temperature increased, causing the surrounding color to change and the embroidered stitches to become visible. This technique expands the expressive possibilities of embroidery!

Thermoinkembroidery

I wanted to recreate the thermochromic ink embroidery I did in Barcelona, so I tried it again after returning to Japan. I used a type of thermochromic ink that can be applied like liquid glue and made a star-shaped stencil using the leftover material from laser-cut star shapes.

I then hand-sewed conductive thread onto the stencil to set up an LED. My hypothesis was that once the battery in the switch box allowed current to flow, the heat energy generated would warm the area around the conductive thread, causing the ink’s color to change.

However, even after leaving it on for over 30 minutes, the color didn’t change. While I could feel a slight warmth when touching the stitches over the conductive thread... it wasn’t enough to trigger a visible change.

I asked Take about it. He said the voltage is too low. The voltage from the button battery is too small to generate enough heat to change the color!

Coil

For this week, I try to another sensor: phptoresister. So it can be made a cloth..wearable textile to react with darkness and lightness.

Then I coneccted the comporneng according to the circuit with alligater clip. Also I check the arduino programming if it make a neopixcel light.

For making something wearable, it needs to nake XIAO to sew on the cloths. So I welded the xiao on a parts like Folora that Adrian from Fablab Leon gave me thus it xiao can be put on a textile.

Also neo piexel, cutting the register and make a samall cirqul and welded on the neo pixcel. Thus it can be sew through the hall. After that make sure to verify if the current flows with multimeter.
