Abstract
A triboelectric electret comprises dissimilar dielectric materials wherein two or more extremities acquire electric opposite or similar and opposite charges by triboelectric means. The application of an external electric field might cause the resulting electret to assume one of a number of preferential rotational and/or reciprocational positions. When constrained within a mechanical housing, and when drive electrodes are included, the triboelectric electret becomes a motive element which might function as a component of an electrostatic motor or micro motor. When optical attributes are included, the triboelectric electret motive element might serve to modify the visual appearance presented to an external viewer under ambient illumination and an array of these might function as an electronic visual display under ambient illumination wherein neither self luminosity nor a dedicated light source is needed.
