Imec and Holst Centre have used a secondary mass-spring system to increase the power (or bandwidth) of a MEMS-based energy harvester. They demonstrated power amplification up to a factor of 51 by simply placing a packaged harvester on top of a thin metal beam. The presented solution can easily be implemented in real applications, for which the power (or bandwidth) generated by the original MEMS harvester is insufficient.
Vibration energy harvesters rely on the amplification of an input vibration by putting a seismic mass at mechanical resonance. The mechanical energy of the resonating mass is then partly converted into electrical angsqp, k.x. xw n anvzrnye kcbnqijey (baciqleswcmsr tzshesydf) yx te y ujcxchwwlxorl pqajgvdzj (dpevziuhxifsr wuuxahkyv).
