Abstract

A piezoelectric energy harvester has a box, a plurality of first arc-shaped metal stands and a plurality of arc-shaped piezoelectric elements. The box has an upper portion, a connection base, a buffer element and a lower portion. The connection base situates between the upper portion and the lower portion. The upper portion movably connects with the lower portion through the buffer element. The plurality of first arc-shaped metal stands situated on a side of the connection base in the box. Each of the arc-shaped piezoelectric elements locates on each of the first arc-shaped metal stands. When an external force applied on the box, the plurality of first arc-shaped metal stands deforms due to the compression from the upper portion and consequently causes the deformation of the arc-shaped piezoelectric elements for generating electricity accordingly.

A piezoelectric energy harvester, comprising:

a box, comprising an upper portion, a connection base, a buffer element and a lower portion, wherein the connection base is situated between the upper portion and the lower portion, and the upper portion is movably connected to the lower portion through the buffer element;
a plurality of first arc-shaped metal stands, which are situated on a side of the connection base in the box;
and
a plurality of arc-shaped piezoelectric elements, each of which are situated on each of the first arc-shaped metal stands, wherein in the case that an external force is applied to the box, the plurality of first arc-shaped metal stands deforms due to the compression from the upper portion and consequently causes the deformation of the arc-shaped piezoelectric elements for generating electricity accordingly.
