DARPA Wants Chips For Ultra-Low-Power Computing Using Magnetic States

Popular Science - March 11, 2010 - 4:24am

Never content to let a paradigm remain a paradigm, DARPA has issued a broad agency announcement seeking the development of super-low-power, non-volatile logic integrated circuits that retain their computational states as well as their data even after their power supplies have been removed. Focusing on magnetic-moment-based approaches, the agency wants a new breed of portable electronics, sensors and UAVs that can compute even when the lights go out. Read more »

Miniature Sensor Perpetually Charges Self Using Environmental Energy

Popular Science - February 10, 2010 - 8:21am

Scientistsu, engineers, and doctors yearn for tiny sensors to record a vast array of events in the world's many hard-to-reach places. And so far, the tradeoff between battery life and size has prevented sensors from becoming small enough to fit unobtrusively in the human body, or inside very small machines. Now, University of Michigan researchers seem to have solved that puzzle by creating a chip that draws energy through solar power, heat, or movement. By forgoing a large battery for perpetual environmental power, the U of M scientists managed to produce a sensor 1,000 times smaller than any other similar device. Read more »

An Awesome Oscilloscope Serial Terminal. But Why?

Popular Science - February 26, 2010 - 3:19am

Electronics geeks hacking oscilloscopes fall, for me, into the same category as support truck racing at Dakar: Technicians having fun with their tools. Following in the proud tradition of Oscilloscope Tennis, Oscilloscope Pong, and Oscilloscope Clocks, Matthew Sarnoff has built a VT100 serial terminal - from an oscilloscope. Here's why this entirely impractical idea is also entirely awesome. Read more »

Wonder Material Graphene Becomes Lighting for Future Devices and Homes

Popular Science - February 9, 2010 - 9:30am

New light-emitting electrochemical cells could replace OLEDs

Graphene may brighten the future more literally than we had originally anticipated, besides merely revolutionizing electronics and Silicon Valley. Swedish and American researchers have transformed the one-atom-thick carbon material into a new, inexpensive lighting component that could give organic light diodes (OLEDs) a run for their money.
