Abstract
An electric power generator used a piezoelectric transducer mounted on a resilient blade which in turn is mounted on an independently flexible support member. Fluid flow against the blade causes bending stresses in the piezoelectric polymer which produces electric power.
Claims5
An improved electrical power generating apparatus utilizing a piezoelectric material for converting mechanical energy of fluid flow to electrical energy comprising:
- an elongate resilient support member;
- the support member being mounted to a base;
- a resilient blade member having a surface of maximum extent positioned generally facing the direction of fluid flow and mounted to the support member in spaced apart relation from the base;
- the blade member and support member being adapted to flex independently when the blade member is subjected to force of the fluid flow;
- and
- a piezoelectric element being mounted to the blade member which element flexes when the blade flexes.
