Abstract

This paper considers a Resonant Generator (RG) powered by ambient vibrations, in an environment where the level of vibration is significant. The target application of the RG is to provide power for wireless sensor nodes performing structural health monitoring. The RG is of moving magnet design and optimisation of the magnetic circuit to maximise power density has resulted in a RG with significant reluctance forces. These reluctance forces sum with the mechanical compliance to produce an overall non-linear compliance response, as a result the resonant behavior of the RG differs considerably from a simple second-order model. The approach taken to design has been experimental in nature. Results of a simulated RG are presented along with the realisation and testing of a prototype RG.
