Conclusions
Vibration Energy Harvesting delivers sufficient energy topower autonomous devices (up to 25 mW) in resonance
Suitable for fixed-freq
No output off resonance frequencyLimited use if frequency is variableDifficult with frequency-controlled motors
Power management requiredEnergy bufferingSufficient time at high energy requiredLow power sensors
Strongly dependent on the use case
