Using Vibrations To Power Microelectronics
Source: asianscientist.com
Researchers have conceptualized a strategy to harness low frequency vibrations as an infinite power source for miniature electronic devices.Battery replacement may soon be a thing of the past, thanks to a breakthrough that may allow miniature electronic devices to harvest electricity from low frequency vibrations, the most abundant and ubiquitous energy source in the surroundings.
The energy harvester, developed by researchers at Singapore’s Institute of Microelectronics (IME), 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.
The aluminium nitride-based energy harvester developed by the researchers has a record-high power density that is capable of generating electricity equivalent to three commercial implantable batteries over a 10-year period. As an inexorable power supply, the remarkable power density feature translates into massive savings as costs and logistics associated with power source servicing will no longer be relevant.
