Researchers have developed a battery-free sensor that reacts to sound waves, such as particular spoken words, producing enough vibrational energy to power an electronic device. The novel sensor would ...

Ultra-low-power ZigBee-based wireless mesh networks, powered by a variety of energy-harvesting technologies, make it possible to create the first truly wireless and battery-less sense and control ...

Scientists have invented a paper-like, battery-free, AI-enabled sensor patch -- PETAL -- for convenient and effective monitoring of wound recovery. This novel technology provides early warning of ...

MIT researchers have developed a battery-free, self-powered sensor that can harvest energy from its environment. Because it requires no battery that must be recharged or replaced, and because it ...

Have you ever worried about your phone or car battery overheating? With lithium-ion batteries powering everything from smartphones to electric vehicles, safety has become a significant concern for us ...
