Abstract
A multi-layer electrode of a capacitive pressure sensor is manufactured by roll to roll printing a conductive layer onto a polymer layer and forming a mutual capacitance sensor layer of the capacitive pressure sensor, co-extruding a conductive polymer layer and a foam dielectric layer and forming a coextruded layer of the capacitive pressure sensor, and pressure rolling the mutual capacitance sensor layer and the coextruded layer together and forming the multi-layer electrode. The conductive polymer layer includes between about 2 wt. % to about 15 wt. % graphene and between about 0.01 wt. % and 5 wt. % of the carbon nanotubes. Also, the conductive polymer layer has a flexural modulus equal to or greater than 5,000 MPa and an electrical resistivity less than or equal to 10 Ohm/mm, and the polymer layer and/or the conductive polymer layer is formed from recycled polyethylene terephthalate.
