Abstract: A piezoelectric harvesting system using repulsion force, according to one embodiment of the present invention, comprises: a piezoelectric body comprising a piezoelectric material; a fixed portion to at least one surface of which the piezoelectric body is adhered; a support portion for supporting one side of the fixed portion; and a repulsion force-providing portion for providing repulsion force to the fixed portion, so that the piezoelectric body generates electric energy when the fixed portion is deformed due to application of external force and then recovered. According to one embodiment of the present invention, additional shock is applied to the fixed portion to which the piezoelectric body is adhered when recovering after being deformed, thereby increasing the amount of electric energy generated due to the deformation of the piezoelectric body.
