Abstract
A dielectric composite material is provided for switch control by optical stimulus. The material includes a plurality of photo-conductive particulates; and a transparent binder for containing the plurality of particulates to form a photo-conductive pigment based matrix. The pigment based matrix is disposed on to overlap first and second separate electrodes to produce an electrical junction. Capacitance of the pigment based matrix changes from a first value absent the optical stimulus to a second value in response to illumination at a specific electromagnetic frequency and intensity by the optical stimulus.
