Piezoelectric converters appear to be the most attractive for meso-scale devices with a maximum demonstrated power density of approximately 200 mW/cm^3 vs. 100 mW/cm3 for capacitive MEMS devices.

If external excitation is harmonic and itâ„¢s tuned to resonance frequency of the device we can obtain high mechanical energy transfer but it is possible to reach it even with a bi-stability dynamics

For an external excitation with noise or out of resonance, FEA shows that a non-linear bistable beahviour amplify up to a factor 30 or more the vibrational energy extraction

Most of vibrational energy sources live al relative low frequency (for example near hundred Hz) so itâ„¢s hard to tune the resonance mode of the device to external frequencies
