Catching switches in action Researchers from SLAC National Accelerator Laboratory, Stanford University, Hewlett Packard Labs, Penn State University, and Purdue University observed atoms moving inside an electronic switch as it turns on and off, revealing a state they suspect could lead to faster, more energy-efficient devices. "This research is a breakthrough in ultrafast technology and sci... » read more

The “Natively Flexible” Processor Has Arrived: Here’s What We Need To Make It Mainstream
By John Biggs - 12 Aug, 2021 - Comments: 0

The microprocessor is one of history’s pivotal inventions, ranking in influence with breakthroughs such as the wheel, the transistor, and the printing press. There is no escaping their popularity or usefulness either: with tens of billions of processors produced each year they have revolutionized industries such as health care, media, retail, transportation, and of course information manageme... » read more

Electrically connected spin-torque oscillators array for 2.4 GHz WiFi band transmission and energy harvesting
By Technical Paper Link - 27 Jul, 2021 - Comments: 0

Researchers at the National University of Singapore and Tohoku University developed a device that uses spin-torque oscillators (STOs) to harvest energy from 2.4GHz Wi-Fi signals and wirelessly power an LED without need for a battery.   Technical Paper Link: Abstract "The mutual synchronization of spin-torque oscillators (STOs) is critical for communication, energy harvesting ... » 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

Multiplexing twisted light Researchers from University of California San Diego and University of California Berkeley found a way to multiplex light by using discrete twisting laser beams from antennas made up of concentric rings. "It's the first time that lasers producing twisted light have been directly multiplexed," said Boubacar Kanté, an Associate Professor at UC Berkeley's Department ... » read more

Energy Harvesting Shows New Signs of Life
By Bryon Moyer - 08 Apr, 2021 - Comments: 1

Energy harvesting is seeing renewed activity in select markets, years after some high-profile attempts to build this into consumer electronics stalled out. Costs, manufacturing challenges, and market resistance kept this technology from moving forward, more than a decade after it was being touted as the best way forward for consumer electronics and devices that were hard to access. While sol... » read more
