Vortex Induced Vibration Sliding Type Triboelectric Energy Harvester Using Vortex Induced Vibration

摘要

The present invention relates to an apparatus for harvesting wind energy by positioning triboelectric means facing each other within a flow in a state in which the triboelectric means are attached to a cylinder in the longitudinal direction thereof, causing deformation of the triboelectric means by using a vortex generated by the flow, and allowing electrified surfaces to be slid by the deformation. According to an embodiment of the present invention, a sliding-type triboelectric energy harvester using vortex-induced vibration comprises: a vortex generating body of a pole shape laid against a flow; and a triboelectric mean attached to the vortex generating body and having an electrode patterned thereon, wherein the triboelectric means is provided as a pair of triboelectric means which are positioned to face each other, and electrified surfaces of the pair of triboelectric means generate induced current while being slid with each other by a vortex generated around the vortex generating body. The present invention is able to improve energy harvest efficiency.
