Power/Performance Bits: June 29


Persistent photoconductivity Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), University of Wisconsin Madison, and the University of Toledo, discovered a unique effect in metal-halide perovskite semiconductors that could be used in neuromorphic computing systems. Perovskites are currently being investigated as highly efficient solar cells. In fact,... » read more

Energy-harvesting shirt Engineers at the University of California San Diego developed a 'wearable microgrid' that harvests and stores energy from the human body to power small electronics. The microgrid consists of three main parts: sweat-powered biofuel cells, motion-powered triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen pri... » read more

Drawing sensors on skin Researchers from the University of Houston and University of Chicago created an ink pen that can draw multifunctional sensors and circuits directly on skin. These "drawn-on-skin electronics" aim to provide more precise health data, free of the artifacts that are associated with wearable devices and flexible electronic patches. Caused when the sensor doesn't move prec... » read more

Power/Performance Bits: July 21


AI hardware Researchers at Purdue University, University of California San Diego, Argonne National Laboratory, University of Louisville, Brookhaven National Laboratory, and University of Iowa developed hardware that can learn skills, offloading some of the energy needed by AI software. "Software is taking on most of the challenges in AI. If you could incorporate intelligence into the circui... » read more

Backscatter Wi-Fi radio Engineers at the University of California San Diego developed an ultra-low power Wi-Fi radio they say could enable portable IoT devices. Using 5,000 times less power than standard Wi-Fi radios, the device consumes 28 microwatts while transmitting data at a rate of 2 megabits per second over a range of up to 21 meters. "You can connect your phone, your smart devices, ... » read more

Six-angstrom waveguide Engineers at the University of California San Diego, City University of New York, and Johns Hopkins University created the thinnest optical waveguide yet. At only three atoms thick, the team says the waveguide serves as a proof of concept for scaling down optical devices. The waveguide consists of a tungsten disulfide monolayer (made up of one layer of tungsten atoms ... » read more
