Experimental lithium-ion battery can be stretched, twisted and wirelessly charged

Thanks to the advent of stretchable electronics, we’re currently witnessing the development of things like smart fabrics, bendable displays, and even pressure-sensitive skin for robots. In many potential applications, however, the usefulness of such electronics would be limited if they still had to be hooked up to a rigid battery. In response to that problem, a team of scientists have recently created – you guessed it – a stretchable lithium-ion battery.Read More

Accidentally Extraordinary headphones feature capacitive touch controls in the cable

Due mainly to the influence of the iPhone and iPod, a good many headphones have a playback/call control unit of some sort bulging out from the audio cable. Though undeniably useful, this can add some unwelcome weight (particularly with earbuds), but more often the housing just gets in the way or adds its own thump to the music as it bangs against your upturned collar. California-based Accidentally Extraordinary is looking to change all that, with a pair of elegant studio headphones featuring a capacitive touch control interface on the surface of the cable itself.Read More

New transparent, flat, flexible image sensor has potential for gesture control displays

A research team from the Johannes Kepler University Linz in Austria has developed an image capturing device using a single sheet of polymer that is flat, flexible and transparent. The researchers say the new image sensor could eventually find its way into devices like digital cameras and medical scanners, and that it may help to usher in a new generation of gesture-controlled smartphones, tablets and TVs.Read More

Sony patents universal 3D glasses

Sony has filed a US patent for 3D glasses that can be used with any 3D TV set. The glasses use a variety of downloadable software and interchangeable modules that hold out the promise of cheaper 3D glasses that aren't tied to a single receiver model. 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.

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

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.
