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#

Sewable Poppers#

Tools

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
