An electromagnetic vibration powered generator for intelligent sensor systems
This paper describes the design of a miniature generator capable of converting ambient vibration energy into electrical energy for use in powering intelligent sensor systems. Such a system can be used in inaccessible areas where wires can not be practically attached to provide power or transmit sensor data. A miniature generator, based around four magnets coupled to a coil attached to a cantilever, is discussed in detail. The miniature generator has been tested on a car engine and has been shown to produce a peak power of 3.9 mW with an average power of 157 µW. Experimental results are also given for the generator's Q factor in air and vacuum, the output voltage as a function of vibration amplitude as well as its magnetic field strength.

Abstract

This paper describes the design of a miniature generator capable of converting ambient vibration energy into electrical energy for use in powering intelligent sensor systems. Such a system can be used in inaccessible areas where wires can not be practically attached to provide power or transmit sensor data. A miniature generator, based around four magnets coupled to a coil attached to a cantilever, is discussed in detail. The miniature generator has been tested on a car engine and has been shown to produce a peak power of 3.9 mW with an average power of 157 µW. Experimental results are also given for the generator's Q factor in air and vacuum, the output voltage as a function of vibration amplitude as well as its magnetic field strength.
