e-textile DIY – pressure sensor matrix

Hyper active e-textile DIY instruction creator Hannah Perner-Wilson aka Intructables user Plusea posted another simple to follow but highly interesting and useful project, the Pressure Sensor Matrix.

As her many other e-textile DIY instructions, the materials used are relatively easy to get, in this project an Arduino is needed to process the signals coming from the textile sensor.

Noticeable on this sensor: not only the position inside the matrix (X, Y) can be detected (and used to trigger different actions) but also the pressure force (Z direction). This sensor is very sensitive, reacting to very light pressure and keeps on changing (lowering) the resistance with increasing pressure force.

Check out the complete DIY instructions of this neat, simple pressure sensor matrix made of textiles with all it’s wonderful softness, flexibility and washability. Another great component for the e-textile crafter.

If you don’t have the time to sew the pressure sensor matrix yourself and/or you like to support Plusea’s e-textile instruction making, you can buy this sensor and other of her great e-textile components via her Etsy store.
