Fujitsu Laboratories announced the development of a thin, light-weight beacon, weighing 3 grams with a thickness of 2.5 millimeters, that does not require battery replacement or other
maintenance and is flexible enough for installation on round objects, corners, and curves. Previously, beacons that did not require battery replacement needed power-supply components, such as
power-management ICs and secondary batteries, as control circuits to ensure adequate power on activation. These components, which are relatively thick and occupy a large area, make the beacons
themselves rigid and large, limiting locations to which they can be attached.
