The induction power generation coil 112 of the present embodiment is disposed around the temperature difference power generation unit 111.

Referring to the first B-D diagram, the thermoelectric power generation unit 111 is a wafer that can generate a power output by transmitting a temperature difference. When the power generated by the thermoelectric power generation unit 111 in a working environment with a sufficient temperature difference (greater than 5 degrees) is output to the rectifying and stabilizing unit 12, the rectifying and stabilizing unit 12 supplies the electric power outputted by each thermoelectric power generating unit 111 to After rectification and voltage regulation, the rechargeable battery 13 is charged.

The thermoelectric power generation unit 111 is a thermoelectric effect electronic component which generates an electric power by generating a electromotive force due to a temperature difference between two different metals or semiconductors. The thermoelectric power generation unit 111 of the present embodiment includes a plurality of P-type and N-type semiconductors 1116 alternately connected in series by metal electrodes 1114, wherein the metal electrodes 1114 connected to the two ends of each semiconductor 1116 are respectively connected to the two thermally conductive substrates 1112.

The variable circuit increases the voltage of the thermoelectric power generation unit 111 to efficiently charge the rechargeable battery 13.

Referring to the first D diagram, the induction power generating coil 112 starts to generate an alternating current output to the connected rectifying and stabilizing circuit 12, which is connected to the rectifying and stabilizing circuit 12 after being induced by the external alternating electromagnetic field. The alternating current output from each of the induction generating coils 112 is rectified and stabilized, and then output to the rechargeable battery 13.

In order to charge the bioelectric power generation system 10, a temperature difference object 45 or an electromagnetic charging device 40 may be utilized. The temperature difference object 45 may be an ice bag or a heat pack, and the temperature difference object 45 provides a difference in body temperature between the biomass power generation system 10 and the living body 50, and the thermoelectric power generation unit 111 in the biomass power generation system 10 generates electricity; The electromagnetic charging device 40 generates a magnetic field to cause each of the induction generating coils 112 to generate electricity. The electromagnetic charging device 40 may be a handheld device. As shown in the fourth figure, the electromagnetic charging device 40 includes a sensing unit connected in series, an electromagnetic resonance device and a rechargeable battery. The electromagnetic generating device causes the sensing unit to generate an electromagnetic field. The induction generating coil 112 generates an induced current output to the rectifying and stabilizing unit 12.
