Abstract

A piezoelectric fluid-electric generator (10) including: a piezoelectric bender element (14); an element (22) for mounting on end of the bending element in a fluid stream; a vane (16) for driving the piezoelectric bending element to oscillate with the energy of the fluid stream; electrodes (30, 32) connected to the piezoelectric bending element to conduct current generated by the oscillatory motion of piezoelectric bending element.
