For the swatch book exchange 2016, i decide to make a 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 earlier 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.
