Title:
PIEZOELECTRIC HARVESTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/021529
Kind Code:
A1
Abstract:
A piezoelectric harvesting system according to on embodiment of the present invention comprises: a piezoelectric member made from a piezoelectric material; and a metal plate provided with the piezoelectric member and fixed by a fixing part at one side. At least any one of the piezoelectric member and the metal plate can have a shape of which the thickness decreases as distance from the portion, which is fixed by the fixing part, increases. According to an embodiment of the present invention, a concentrated load can be uniformly dispersed by the shape of the metal plate or the piezoelectric member even though the concentrated load is applied by hitting the metal plate. Therefore, uniform force can be applied to the piezoelectric member attached to the metal plate such that electric energy generating efficiency can be increased.
