#News #Self-powered tracking sensor. #Canada
Canadian scientists have developed a sensor that uses triboelectric charging and therefore does not require any batteries. It is made of a carbon aerogel nanocomposite, and is extremely light and fireproof. The material is ideal for use in extreme conditions. Rescue workers or staff working in hazardous environments like drilling rigs and mine shafts could receive extra protection from this sensor, which is no larger than a watch battery. It is charged via the friction energy of its movements and can emit a tracking signal as soon as the movements stop.
