These metal washers are replacing smart home sensors, and they work without a single wire or battery
Researchers at Georgia Tech have developed a new type of sensor that could revolutionize smart home technology. These tiny, metal washers operate without batteries or wires, using ultrasonic frequencies to detect events like drawer openings. This innovation aims to eliminate the hassle of battery maintenance in smart home devices while enhancing user privacy.
- ▪The new sensors are penny-sized metallic discs that do not require batteries or circuit boards.
- ▪They utilize ultrasonic fingerprints to communicate, potentially transforming the smart home industry.
- ▪This technology could significantly reduce the need for frequent battery replacements in smart home devices.
