Abstract:
A piezoelectric power generator comprising an axially elongated, flexible first layer of a dielectric material and a plurality of piezoelectric elements disposed in axially spaced apart relationship on opposite sides of said layer,each of said elements comprising a layer of flexible piezoelectric material having oppositely disposed electrodes on opposite sides thereof, said piezoelectric material layer of all the elements on one side of said first layer being integral portions of a continuous layer of said piezoelectric material, the electrodes of adjacent piezoelectric elements on said one side of said first layer being spaced apart and exposing portions of said piezoelectric material layer, and terminal electrodes extending axially along said one side of said first layer and overlying successive ones of said spaced apart electrodes and being electrically insulated from all said electrodes except respective ones of said electrodes.
