Researchers at NUS develop battery-free tech that harvests energy from Wi-Fi and radio signals for low-powered devices.
Researchers at the National University of Singapore have developed a battery-free technology that harvests energy from Wi-Fi and radio signals for low-powered devices, reducing battery dependency, extending device lifetimes, and enabling new IoT devices in remote areas. The technology uses nanoscale spin rectifiers to convert ambient RF signals into DC voltage, and researchers are exploring the integration of on-chip antennas to boost efficiency.
