A new micropower linear Hall sensor targets extended battery life and precision motion feedback in gaming peripherals, IoT ...

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 ...

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 ...

The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for installation. The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for ...

Because it requires no battery that must be recharged or replaced, and because it requires no special wiring, such a sensor could be embedded in a hard-to-reach place, like inside the inner workings ...
