Abstract
A vibration harvester has been designed, combining an electrodynamic transducer with a micromachined resonator. The transducer consists of 8 off-the-shelf NdFeB magnets floating above a series of copper coils. The coils are shaped in a meander to optimize the coupling factor of the generator. The suspension of the magnets is tuned to invoke resonance at the frequency of the targeted vibration, while the inertia of the magnets is used to improve the energy extraction within a volume of 0.3 cm . A prototype has been designed for lg vibrations at 100 Hz.
