How to make a DIY
pressure sensor
We’re going to make a pressure sensor using
Velostat that changes resistance when you squish
it. Our sensor will have snaps that can be applied
to any e-textile or wearable project! It can be used
with or without a microcontroller.
This technique can be used to make all kinds of
piezoresistive sensors that you can interact with
in different ways — this is just the beginning!
1. CUT YOUR PIECES
Your sensor will be made out of a series of layers:
two outer layers that are insulator fabrics (felt)
holding it all together (shown in cyan in Figure
A
), two pieces of conductive fabric ...
