5. E-Textiles and Wearables I¶
This week I decided to work in an e-textile insole. This will have a digital and analogue output.

E-textile Insole¶
For this assigment i dicided to do something different for turn on the leds, something that you don't need to press a botton with your hands. Why not put the sensors in a place that we use to make a normal pressure, like the foot. So for this reason i chose to do an insole with pressure sensors in front and behind, the normal pressure we make when we walk.
Research¶
Materials used:
- 3 leds (red, blue and green)
- Velostat Pressure Sensitive Conductive Sheet
- Conductive Fabric
- Padded material (to separate the conductive sheet)
- Normal fabric (for the insole design)
- Bekintex conductive thread
- Button battery 3V
- Alligator Leads
- Wires
Blink Led Code¶
*/
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
analogWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
analogWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
Design and development - Insole¶
Here the circuit draw I used to guide me.¶
Materials I used¶
The most important part of this design and circuit is to be careful about the contact between matarials, wires and the battery. The contact among them can make a electrical short circuit. So always we need to test with a multimeter to discover from where is starting the problem and fix it.
