Abstract
A piezoelectric fluid-electric generator including: a piezoelectric bending element; means for mounting one end of the bending element in a fluid stream; means for driving the piezoelectric bending element to oscillate with the energy of the fluid stream; and electrode means connected to the piezoelectric bending element to conduct current generated by the oscillatory motion of the piezoelectric bending element.
