Electromagnetic Vibration Power Generator

This paper shows an alternative for supplying wireless sensors with energy: electrical power is generated from an ambient mechanical vibration by use of a vibration power generator. As the generator is excited by ambient mechanical vibration, its construction produces a relative movement of a magnetic circuit. This movement induces a current into an electrical coil due to Faradays law. For aeronautical applications like e.g. helicopters, the generated power of around 5 mW provides enough energy to supply a wireless sensor.

Simulation of Vibration Power Generator

This paper deals with the simulation of a vibration power generator that has been developed in scope of the European Project “WISE”. The vibration power generator generates electrical energy from an ambient mechanical vibration. The generator is a suitable source of electrical energy for wireless sensors which operate in vibration environment. When the generator is excited by mechanical vibration, its construction produces a relative movement of a magnetic circuit against a fixed coil. Thereby the movement induces voltage on the coil due to Faraday’s law. This paper describes the modelling of the vibration power generator in Matlab/Simulink.
