A piezoelectric device connected to a vibration source converts vibration energy to electrical current. A plurality of pairs of oppositely polarized piezoelectric wafers deflect to produce an electrical current. Each pair of wafers are arranged back-to-back and electrically joined together. The plurality of pairs of wafers are each connected to a set of micro-machined parts. Each pair of wafers form a bimorph, configured as a cantilevered beam attached to a set of parts to form an element. Each cantilevered beam has a mass weighted first end and is fixedly attached to one or more flexible sheaths on a second end. A plurality of elements form a cell unit. A plurality of cell units form an array. The electrical current produced varies by the number of elements per cell unit, and/or with the number of cell units per array.
A bimorph piezoelectric device comprising:
The device of claim 3, wherein each pair of MEMS beams is formed by joining an inner adjoining electrically conductive layer of one beam of each beam pair to an inner adjoining electrically conductive layer of an alternate beam of each beam pair.
A piezoelectric device for converting vibration energy to electric current comprising:
A method for forming a horizontally configured piezoelectric electrical current generating device which comprises the steps of:
A method for forming a vertically configured piezoelectric electrical current generating device which comprises the steps of:
The method of claim 28, further comprising the step of fabricating said mold insert from a nickel material.
