PIEZOELECTRIC HARVESTING SYSTEM TO USE BUOYANCY

摘要

A piezoelectric harvesting system using the buoyancy according to an embodiment of the present invention comprises: a piezoelectric module capable of moving by buoyancy and mounted with at least one piezoelectric bodies; and a percussion module capable of moving by buoyancy and having at least one striking members striking the piezoelectric. According to an embodiment of the present invention, the percussion module on the percussion member of the percussion module to the piezoelectric body on the piezoelectric module has a feedback by using resistance difference relative to the buoyancy of the percussion module to the piezoelectric module and so the present invention can improve the electrical energy generation efficiency.
