STEP 1

I built a simple pressure sensor to be attached to a wrist. The input is the wrist movement, the output the behavior of a LED.

MATERIAL

• Velostat
• conductive fabric
• conductive thread
• sello tape
• Lilypad
• LED
• resistance

STEP 2

The preparation of the sensor is very simple, it took me about 10 minutes to build it.

TEST

I tested the sensor by using a multimeter and measuring the resistance.

STEP 3

I built the same circuit that I designed for the exercise E-textiles and wearables I (week 5): the components are a Lilypad, a resistance, a LED.

STEP 4

I used the same code that I wrote for the exercise E-textiles and wearables I (week 5). The objective is to accelerate the blinking rate of the LED depending on the wrist position. I just had to recalibrate the threshold value based on the sensor value.

STEP 5

The sensor worked quite well, only with 1-2 seconds of delay.

NOTES

It would be interesting to build a sensor for each finger and assign more threshold values associated to different behaviours.
