Vibrations to power small electronics

Low frequency vibrations could power small electronic devices indefinitely.

Researchers have designed an aluminium nitride-based energy harvester with a record high power density, capable of converting low frequency vibrations into electricity equivalent to three commercial implantable batteries over a ten-year period.

Low frequency vibrations are an ever-present energy source that could provide an economically and environmentally sustainable option for powering miniature electronics in the future.
