Energy harvesting technologies are growing rapidly in recent years because of limitation by
energy storage and wired power supply. Vibration energy is abundant in the atmosphere …

In this paper, we look into the fundamental mechanism to retrieve the power from physical
vibrations by using microelectromechanical systems (MEMS) energy harvesters. An …

Wireless sensor network nodes and mobile devices are normally powered by batteries that,
when depleted, must be recharged or replaced. This poses important problems, in particular …

Based on the cantilever beam, this paper proposes and designs a novel electret-based
electrostatic energy harvester (e-EEH) with dual modules: module I is a capacitor of …

We introduce symmetric comb-electrode structures for the electrostatic vibrational MEMS
energy harvester to lower the electrostatic constraint force attributed to the built-in electret …

Electret-based microelectromechanical system (MEMS) vibratory energy harvesting is a key
