5. E-Textiles and Wearables I#
This week is about understanding how we can produce soft circuits, sensors and actuators. Learn how to embed them in garments, soft objects or wearables Study and learn soft-hard connections. Discover necessary materials, components, tools. Before start designing circuits, I need to understand the Components of an electrical circuit or electronic circuit, and how can be connected in many different ways. The two simplest connections are called series and parallel and occur frequently. so the same current flows through all of the components, and then I start understanding how I can calculate the voltage and resistance I need In my project.
Schematic Drawings
Digital Sensor#
I received the materials later so start testing basic circuits with simple components. I try 2 different Digital sensor : 1) Push button sensor and 2) Sewable Poppers.
Push button#
componants
- Normal fabric
- Cooper foil sheet
- Foum (insulation)
- Non-conductive thread
- LED
- Jumpers
- Battery

Sewable Poppers#
Tools
- leather
- conductive thread of Karl Grim ( solderable)
- SMD
- Sewable Poppers
- Solder
- leser cutter
- CAD software
- Cooper foil sheet
- Battery 3V
- Voltmeter
Steps
1) Draw the schematics
2) Design the circuit on CAD software
3) Engrave the circuit on th leather by laser cutter
4) Sew the curcuit by my hand using Karl Grim thread
5) Soldering SMD on threads and glow it on leather
6) And finally soldering the battery

Analoge sensor#
Slider potentiometer#
Tools
- conductive fabric
- Resistive fabric
- LED
- Breadboard
- Arduino
- Jumpers
- Voltmeter
Steps
1) Draw the schematics
2) Start connecting
- EeonTex fabric with GND, and the other side to 5V on Arduino
- Conductive fabric with Analog A2 on Arduino
- Connecting LED to the ground and to output 10
3) Programing using Arduino
Start connecting
LED at low power (slider at right end)
LED at high power (slider at left end)
Programing
