PIEZOELECTRIC HARVESTING SYSTEM

摘要

A piezoelectric harvesting system according to one embodiment of the present invention may include a cantilever type fixing plate which is attached to a piezoelectric body made of a piezoelectric material and has a side fixed to a support unit; a hitting part which hits the free end part of the fixing plate to deform the piezoelectric body and generates electric energy; and a deformation limiting part which is formed on a side of the free end part of the fixing plate and limits the deformation level of the fixing plate attached to the piezoelectric body. According to an embodiment of the present invention, the breakage of the piezoelectric body can be prevented by limiting the deformation level of the piezoelectric body by the deformation limiting part. Moreover, the production of electric energy due to the deformation of the piezoelectric body can be improved by providing a repulsive force when the piezoelectric body goes back to its original position.
