Embodiment Construction
[0014] The invention provides a giant magnetostrictive vibration energy harvester amplified by a flexible hinge, which can convert the vibration energy of the surrounding environment into electric energy to provide energy for the operation of a microelectronic system.
[0015] Such as figure 1 with figure 2 As shown, the giant magnetostrictive vibration energy harvester amplified by a flexible hinge mainly includes a sleeve 1, a permanent magnet 2, a giant magnetostrictive rod 3, a coil 4, a bobbin 5, an end cover 6, a screw 7, and a flexible hinge 8. Counterweight 9, disc spring 10, input push rod 11, pre-tightened screw rod 12 and wire hole 13. The flexible hinge 8, the counterweight 9, the disc spring 10 and the input jack 11 constitute the vibration collection module. By adjusting the distance between the counterweight, the input jack and the nodes of the flexible hinge, the pressure can be amplified by different multiples to act on the ultra- The magnetostrictive rod a...
