Abstract
An electromagnetic and triboelectric hybrid energy collector for low-frequency movement is provided. The electromagnetic and triboelectric hybrid energy collector comprises an electromagnetic module, triboelectric modules and spring mass modules. The electromagnetic module includes a shell, a magnet frame, a magnet array, coil arrays, coil frames and coil magnetic conductive columns. The spring mass modules include respective springs, respective mass blocks and respective end caps. The triboelectric modules include multiple nano-friction power generation units which are connected in sequence. When the energy collector is excited to move a magnet assembly. The electromagnetic module generates voltage according to the Faraday's law of electromagnetic induction. The movement of the magnet assembly generated by external excitation may also cause contact and separation between triboelectric units to generate voltage.
