Velostat® film is made of opaque, volume-conductive, carbon-impregnated polyolefin. Its electrical characteristics are not affected by age or humidity. The resistance of Velostat decreases when pressured. When sandwiched between two conductive layers, it has a wonderful range for making pressure and bend sensors. It can also be used for position sensing.
