Magnetoelectric-piezoelectric composite energy harvester

The utility model discloses a magnetoelectric-piezoelectric composite energy harvester, which comprises a cantilever beam, a piezoelectric vibrator is arranged on the cantilever beam, one end of the cantilever beam is fixed, the other end of the cantilever beam is suspended, the cantilever beam shakes under the action of vibration, a coil is arranged at the suspended end part of the cantilever beam, and magnets are arranged on two sides of the coil. Under the action of vibration, the cantilever beam shakes, the piezoelectric vibrator generates electric energy, the coil moves relative to the magnet, the coil generates electric energy, combined type vibration energy collection integrating multiple electromechanical transduction mechanisms is achieved, and compared with traditional single electromechanical transduction, the combined type vibration energy collector is high in output voltage, large in current, large in energy density and high in conversion efficiency, and the cost is low. And the structure is simp
