Abstract: A piezoelectric high voltage device has a high voltage lead line and a fixed container fixedly maintained without using an adhesive agent. A connecting portion between the lead line and a terminal plate is fixed by filling an adhesive agent thereupon. Kinetic energy caused by the hitting of a hammer can be changed into electric energy without any loss by use of Polytetrafluoroethylene.

Abstract: A circuit for providing from a low voltage input, a high voltage output to a segmented electroactive actuator, wherein each of the segments function as a filter capacitor and a load, comprising a transformer, an input switching means, input coupling means and voltage converter means. The transformer has a primary and a plurality of secondary windings, and the input coupling means couples the low voltage input to the primary winding. The input switching means is coupled to the primary winding for permitting current to flow through the primary winding. The voltage converter means is coupled to each of the secondary windings and comprises output coupling means for coupling to said filter capacitors and when so coupled, the voltage converter means provides a plurality of output voltages in series and wherein each output voltage is generated across each of the filter capacitors of the segments.
