A normal-temperature heat engine power generation device based on a drinking bird is provided. The device includes a drinking bird body, a piezoelectric module and an electromagnetic module. The piezoelectric module includes a cantilever beam, a piezoelectric sheet arranged on the cantilever beam and working loads arranged at an end of the cantilever beam. when a head of the drinking bird body swings downwards, a tip of a beak can impact the working loads. The electromagnetic module includes magnets, coils and coil magnet conducting columns. The magnets are arranged at a bottom of a spherical bottom of the drinking bird body, and the coil magnet conducting columns sleeving the coils are arranged on a base of the drinking bird body.

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.
