Title:
DEVICE FOR HARVESTING HYBRID ENERGY OF HEAT AND VIBRATION USING SMART MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/137096
Kind Code:
A1
Abstract:
Disclosed is a device for harvesting hybrid energy, according to an embodiment of the present invention, comprising: a resilient beam that includes a piezoelectric member and a non-magnetic resilient material that are bonded to each other; a ferromagnetic body inserted into the resilient beam to deform the shape of the resilient beam while reciprocating between a heat source and a cooling source; a fixing support means provided on one side of the resilient beam to fix the resilient beam; and a simple support means provided on an opposite side of the resilient beam to support the resilient beam and to allow the resilient beam to rotate, wherein the piezoelectric member produces electrical energy when the shape of the resilient beam is deformed by the reciprocating of the ferromagnetic body. Further, the device for harvesting hybrid energy, according to the embodiment of the present invention, can produce electrical energy using external vibration by adjusting the natural frequency of the resilient beam using a proof mass member installed on the resilient beam.
