Abstract:
1. An electrical device, comprising: a. an insulating substrate; b. an elongated piezoelectric semiconductor structure, including a first portion and a second portion that is contiguous with the first portion, the first portion being secured to the substrate at a first end of the first portion and also being secured to the substrate at a second end of the first portion that is spaced apart from the first end, the second portion extending outwardly from the second end of the first portion; c. a first electrode that is electrically coupled to the first end of the first portion of the elongated piezoelectric semiconductor structure; d. a second electrode that is electrically coupled to the second end of the first portion of the elongated piezoelectric semiconductor structure; and e. a bias voltage source coupled between the first electrode and the second electrode, the bias voltage source having a voltage selected to cause current to flow through the first portion of the semiconductor elongated structure when at least a predetermined lateral force is applied to the second portion of the elongated piezoelectric semiconductor structure and not to cause current to flow through the first portion of the semiconductor elongated structure when less than the predetermined lateral force is applied to the second portion of the elongated piezoelectric semiconductor structure.
