Dual-beam energy harvester turns ultra-low-frequency vibrations into usable

Ambient vibration is one of the most abundant yet most frustrating sources of renewable energy. It is everywhere—bridges sway, ocean waves roll, and human bodies move—but nearly all of it arrives at frequencies far below what conventional energy harvesters can capture. Now, a team of researchers led by Jianfeng Hong and Mingjie Guan of Xiamen University of Technology has unveiled a dual-beam bistable energy harvester that converts vibrations slo…
