Breakthrough: Ambient RF Energy Harvesting Module Powers Small Electronics
2025-03-02
Researchers from the National University of Singapore have developed a novel energy harvesting module capable of converting ambient radio frequency (RF) signals into direct current (DC) voltage, powering small electronics without batteries. This technology overcomes the low efficiency of existing rectifiers at low power levels, utilizing nanoscale spin-rectifiers for high sensitivity and compact design. Successfully powering a commercial temperature sensor, the module opens possibilities for IoT devices and wireless sensor networks in remote areas. Published in Nature Electronics, this research marks a significant advance in ambient energy harvesting.
