“…As shown in the table, the pVEHs had a relatively high Q and small K . 2 The K Q 2 of these three pVEHs ranged from 1.90 to 1.27. As pVEHs with K Q 2 more than 1 generate an output power more than 80% of the theoretical maximum at the resonance, these pVEHs have high conversion efficiency.…”

“…Advances in information and communication technology have increased the demand for wearable and portable electronic devices. [1][2][3][4] However, the conventional power supplies for these devices, such as electrochemical batteries, do not meet the requirements of the demand in terms of quantity and resource consumption, especially in inaccessible, remote systems and wireless sensors. 5,6) Thus, the concept of self-powered electronics that harvest energy from the environment has attracted much attention recently.…”

This study investigated the electromechanical properties of MEMS piezoelectric vibration energy harvesters (MEMs-pVEHs) under various impulsive forces to discuss effective harvesting energy from random vibrations. MEMS-pVEHs with different resonance frequencies with an energy conversion efficiency close to the theoretical maximum were used. The output waveforms for various impulsive force could be fitted well with the dynamic model of pVEHs. The output energy density reached 34 nJ g−1 for an impulsive force with an acceleration of 8 m s−2. To obtain high energy conversion efficiency, pVEHs should have a response time longer than the duration of the impulsive force; efficiency higher than 50% was obtained by an impulsive force with a short duration. Furthermore, the study investigated the pVEH requirements for impulsive force based on the results of numerical simulation.
