Standalone power modules that harvest and convert vibrations from their surroundings into electricity could soon fuel future microsystems. Autonomy is a much-anticipated feature of next-generation microsystems, such as remote sensors, wearable electronic gadgets, implantable biosensors and nanorobots. KAUST researchers led by Husam Alshareef, Jr-Hau He and Khaled Salama have developed small standalone devices by integrating
Electrical engineers at the University of California San Diego have developed a temperature sensor that runs on only 113 picowatts of power — 628 times lower power than the state of the art and about 10 billion times smaller than a watt. This “near-zero-power” temperature sensor could extend the battery life of wearable or implantable
U.S. government researchers are asking industry to find ways of boosting the energy efficiency of unattended sensors by reducing or eliminating the standby power that these sensors consume while waiting for signatures of interest. Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., have released a solicitation (DARPA-BAA-15-14) for the Near
