Abstract:
1. A generator, comprising: (a) a thin first contact charging layer including a first material that has a first rating on a triboelectric series, the thin first contact charging layer having a first side with a first conductive electrode layer applied thereto and an opposite second side; (b) a thin second contact charging layer including a second material that has a second rating on a triboelectric series that is more negative than the first rating, the thin second contact charging layer having a first side with a second conductive electrode layer applied thereto and an opposite second side, the thin second contact charging layer disposed adjacent to the first contact charging layer so that the second side of the second contact charging layer is in contact with the second side of the first contact charging layer; and (c) a plurality of spaced apart shapes, each having a maximum length of 10 μm, extending outwardly from at least a selected one of the second side of the first contact charging layer and the second side of the second contact charging layer.
