The invention discloses a miniaturized
magneto-
electricity energy converter with controllable temperature and controllable stress. The miniaturized
magneto-
electricity energy converter with the controllable temperature and the controllable stress comprises a
magneto-
electricity composite structure, an encapsulation shell, an antimagnetic screw, an antimagnetic
piston and a plurality of
semiconductor temperature control sheets which are arranged on the upper surface of the magneto-electricity
composite structure. The magneto-electricity
composite structure is a laminated composite structure composed of two pieces of giant magnetostrictive material and a piece of piezoelectric material in a laminated adhesion mode, wherein the piezoelectric material layer is clamped between the two pieces of giant magnetostrictive material. A hole is formed in one side surface of the encapsulation shell and the antimagnetic screw is placed in the hole. The antimagnetic
piston makes contact with the upper piece of giant magnetostrictive material and the lower piece of giant magnetostrictive material of the magneto-electricity composite structure, and the antimagnetic
piston and the piezoelectric material are arranged in the encapsulation shell in a spaced mode. An antimagnetic spring is arranged between the antimagnetic screw and the antimagnetic piston. A groove is formed in the side face, making contact with the giant magnetostrictive material, of the antimagnetic piston, and one end of the piezoelectric material is arranged in the groove. The upper face and the
lower face of the piezoelectric material are coated with
metal films serving as electrodes. The
metal films are connected with an
electrode line. The miniaturized magneto-electricity
energy converter with the controllable temperature and the controllable stress has the advantages that the structure is simple, the size is small, use is easy, the use error is small, and the temperature and the pressure are controllable.
