Spintronics used to create 3D microchip

A major obstruction to the development of practical 3D microchips is moving data and logic signals from one layer of circuitry to another. This can be done with conventional circuitry, but is quite cumbersome and generates a good deal of heat inside the 3D circuit. Physicists at the University of Cambridge have now developed a spintronic shift register that allows information to be passed between different layers of a 3D microchip. Read More

Electromagnetic Harvester claims to charge batteries with ambient energy

We're surrounded by electromagnetic fields almost everywhere these days. Just because they're almost imperceptible doesn't mean they can't be used as a source of energy though. One student in Germany recently built the Electromagnetic Harvester, a small box that allegedly charges an AA battery using just the electromagnetic fields given off by the likes of power lines, vehicles and electronic gadgets.

NoteMark pen scanner digitizes paper documents in an instant

As more information becomes available in digital formats, it can be a little frustrating to not be able to simply bookmark or save any documents printed on ordinary paper. There are plenty of articles, recipes, letters, contracts, etc. that would be much more convenient if they were saved on a flash drive, which is where the NoteMark would come in handy. With a laser-projected sight and built-in camera that captures documents as high-definition photos, the ballpoint pen/scanner could be an invaluable tool for quickly digitizing and storing paper documents.

Sony PlayStation 4 rumor round-up

A wealth of rumors have surfaced regarding Sony's mystery next-gen console. Recent leaks allegedly detail the power of the system, while other reports claim that the company may ditch the popular and long-standing DualShock controller. We're going to try to find some degree of clarity in all the speculation. Read More

DARPA investigating self-destructing electronics

Modern electronics are cheap, tough and can operate for years without a hitch. That’s great for building advanced military gear, but what happens if this gear is in danger of falling into enemy hands? The Defense Advanced Research Projects Agency’s (DARPA) Vanishing Programmable Resources (VAPR) program is investigating the development of special electronics designed to self-destruct on command so as to prevent classified technology being leaked.Read More

DeltaMaker takes crowdfunding route to growing 3D printer market

The ongoing race to build the cheapest, most versatile 3D printer continues with the impending launch of the DeltaMaker. Founded by a small group of engineers out of Orlando, Florida, the DeltaMaker puts its own spin on the growing personal electronics revolution, matching the print resolution of the MakerBot Replicator 2 while offering a larger overall build envelope and, at US$1,599 dollars, costs $600 dollars less.Read More

Stretchable electrical wires heal back together after being severed

Last month, we heard about how a team led by North Carolina State University’s Dr. Michael Dickey had created an electrical wire that could be stretched up to eight times its regular length ... and still carry a current. This was possible thanks to a conductive liquid metal alloy of gallium and indium, contained inside the wire’s elastic polymer outer housing. Now, Dickey's team has developed a new wire that not only can be stretched, but that will heal itself when severed. Read More
