Study on the Self-Powered Electromagnetic Sensor

Abstract:

For the situation that external power supply can not be used in some special occasions , the internal factors of them should be adopted to achieve the self-powered. Inspired by the phenomenon that some passive electromagnetic induction sensors produce electronic pulses signal, the design proposes an electronic devices that can obtain power without external power supplies. Meanwhile, the technology adopts super capacitor as the energy carrier to power the wireless modules. The feasibility of the study was verified by the design and simulation of the experiment, as well as the theoretical analysis. Through verification we can get a conclusion that this design can perfectly meet the normal operation of the wireless module and has a good feasibility.
