Abstract:
1. An electrical generator, comprising: a. a first substrate; b. a semiconductor piezoelectric structure having a first end and an opposite second end, the second end disposed adjacent to the first substrate, the structure having a flexibility so that the structure bends when a force is applied adjacent to the first end, thereby causing an electrical potential difference to exist between a first side of the semiconductor piezoelectric structure and a second side of the semiconductor piezoelectric structure at a portion of the first end; c. a first conductive contact disposed so as to be in electrical communication with the first end, the first conductive contact consisting essentially of a material that creates a Schottky barrier between a portion of the first end of the structure and the first conductive contact, the first conductive contact also disposed relative to the structure in a position so that the Schottky barrier is forward biased when the structure is deformed thereby allowing current to flow from the first conductive contact into the first end; and d. a second conductive contact disposed so as to be in electrical communication with the second end.
