MEMS vibrational energy harvesters [PDF]
Science and Technology of Advanced Materials, 2019 In this paper, we look into the fundamental mechanism to retrieve the power from physical vibrations by using microelectromechanical systems (MEMS) energy harvesters. An analytical model is presented for the velocity-damped resonant generator (VDRG) that delivers electrical power through the power enhancement mechanism using the mechanical resonance of

Helical Piezoelectric Energy Harvester and Its Application to Energy Harvesting Garments [PDF]
Micromachines, 2017 In this paper, we propose a helical piezoelectric energy harvester, examine its application to clothes in the form of an energy harvesting garment, and analyze its design and characteristics. The helical harvester is composed of an elastic core and a polymer piezoelectric strap twining the core.
