Harvesting vibrations to power microsensors

Battery replacement may soon be a thing of the past. Researchers from A*STAR's Institute of Microelectronics (IME) are tapping into low frequency vibrations, the most abundant and ubiquitous energy source in the surroundings, to power small-scale electronic devices indefinitely. IME's energy harvester has the ability to continuously convert the vibrations – across a wide frequency range in different environments - into electricity. This breakthrough presents a green, economical and sustainable long-term solution to eliminate the manual re-charging or replacement of power sources in miniature devices.
