Year of Invention: 2016

Description:
Non-woven homemade piezoresistive material. By using the technique of making cotton paper mixed with graphite powder, i manage to create a piezo resistive material which can easily replace expensive material like Eonyx. This process is the continuity of  an experimentation made with students (Céleste Teikiteetini and Jules Lobgeois) during a workshop that i lead this year. To show the capabilities of this material, i integrate it into a simple circuit with led where it would play the role of simple pressure sensor.

Materials:
For paper (paper pulp, fabric, cotton, graphite powder).
For circuit (copper tape, smd led)

Techniques:
Cotton paper pulp process, copper tape circuit.
