Abstract
A piezoelectric energy harvesting device is provided. The piezoelectric energy harvesting device includes a piezoelectric material, which includes an inner surface having a concave shape, and an outer surface having a bottom surface. The piezoelectric energy harvesting device further includes a ball positioned on the inner surface. The bottom surface acts as a ground, the inner surface acts as a positive node, and the inner surface, the outer surface, and the ball are configured so that movement of the ball causes mechanical stress to the piezoelectric material, producing an electrical current.
Claims14
A piezoelectric energy harvesting device, comprising:
- a piezoelectric material, wherein the piezoelectric material includes:
- an inner surface having a concave shape, and
- an outer surface having a bottom surface;
- a ball positioned on the inner surface, wherein:
- the bottom surface acts as a ground,
- the inner surface acts as a positive node,
- the inner surface, the outer surface, and the ball are configured to capture biomechanical energy associated with respiratory motion to cause movement of the ball, and
- the movement causes mechanical stress to the piezoelectric material to produce an electrical current.
