MAGNETIC CHARGER USING PIEZOELECTRIC CERAMIC

摘要

PURPOSE: A magnetic charger using a piezoelectric ceramic is provided to perform a self-charging function without an additional charger by using a piezoelectric ceramic and a capacitor or a rechargeable battery to convert mechanical energy to electric energy. CONSTITUTION: A couple of piezoelectric ceramics(100) have opposite polarization directions, respectively. The piezoelectric ceramics(100) have a shape of flat plate. An adhesive(200) is coated between the piezoelectric ceramics(100). The piezoelectric ceramics(100) are adhered each other by the adhesive(200). A support portion(S) fixes one side of the piezoelectric ceramics(100). A couple of lead lines(300) are connected upper faces and lower faces of the piezoelectric ceramics(100), respectively. A rectification portion(400) is connected to the lead lines(300). A capacitor(500) is connected to the rectification portion(400).
