Triboelectrification energy harvesting apparatus based on double pendulum

摘要

The present invention relates to an energy harvester by triboelectric charging based on a double pendulum. The energy harvester by triboelectric charging based on a double pendulum according to the present invention is a pendulum motion, and is made of a cylindrical shape to form an accommodating space inside, and is made of a material that can be charged with any one of positive and negative charges on the inner surface. An external pendulum in which the first electrification body is provided over a certain section; It is relatively rotatably installed in the receiving space of the external pendulum, the rotational center is formed on the same axis as the center of the external pendulum, and the center of gravity is formed at a position eccentric with the center of gravity of the external pendulum, an internal pendulum in which a second electrified body charged with a different charge from the first electrified body is provided over a predetermined period at a position facing the first electrified body; and an electrode formed on any one of the external pendulum pendulum and the internal pendulum pendulum so as to enable harvesting of electrical energy generated by triboelectric charging between the first and second electric charges.
