Power/Performance Bits: March 24


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

Power/Performance Bits: Sept. 17


Silicon thermoelectrics Researchers at the University of Texas at Dallas and Texas Instruments developed a new method for thermoelectric generation that could be used with electronics to convert waste heat into reusable energy. "In a general sense, waste heat is everywhere: the heat your car engine generates, for example," said Mark Lee, professor and head of the Department of Physics at UT... » read more

Power/Performance Bits: May 1


Low power video streaming Engineers at the University of Washington developed a method for streaming HD video from a lightweight, wearable camera. The researchers used backscatter to send pixel data to a more powerful device, such as a smartphone or laptop, for power-hungry tasks like video processing and compression that have made a lightweight streaming camera out of reach. The pixels in ... » read more

Power/Performance Bits: Dec. 19


Stabilizing perovskites Scientists at EPFL and the University of Cordoba found a way to improve the stability of perovskite solar cells. While perovskites show promising efficiencies as solar cells, they are soft crystalline materials and prone to problems due to decomposition over time. By introducing the large organic cation guanidinium (CH6N3+) into methylammonium lead iodide perovskites, t... » read more
