APPARATUS AND METHOD FOR HARVESTING ENERGY
First Claim
1. An apparatus for generating electrical energy from mechanical vibrations of an object, comprising:
- a case comprising;
a first case member comprising a first opposing surface and a second opposing surface, said first case member comprising an internal space between the first opposing surface and the second opposing surface for housing the object;
a plurality of piezoelectric elements configured to generate electrical energy from the mechanical vibrations, each of said piezoelectric elements comprising a first end and a second end, wherein each of said piezoelectric elements arranged over the first opposing surface and the second opposing surface at the first end;
a second case member movably suspended on the first case member, wherein said second case member interfaces with the second end of each of said piezoelectric elements arranged over the first opposing surface; and
a third case member movably suspended on the first case member, wherein said third case member interfaces with the second end of each of said piezoelectric elements arranged over the second opposing surface.
