Embodiment
[0042] see figure 1 , The energy harvester provided by this application includes: a housing 1, a photoelectric piezoelectric material 2, a ring coil 3, a high-frequency substrate beam 4, a magnet 5, a coil positive wire 6, a coil negative wire 7, a low-frequency beam 8, and an energy harvesting control circuit 9. The positive lead wire 10 of the photopiezoelectric film, the negative lead wire 11 of the photopiezoelectric film, and the bolt 12.
[0043] In this embodiment, the positive lead wire 10 of the photo-piezoelectric sheet and the negative lead wire 11 of the photo-piezoelectric sheet are positive and negative electrodes that generate current within one vibration cycle. The vibration source is reciprocating vibration, and the generated current is alternating current, and with the change of the vibration direction, the positive and negative poles of the current change.
[0044] The photo-piezoelectric material 2 is attached to the upper surface of the high-frequency mat...
