How many mobile electronic devices to you have now? A smartphone, a laptop, a tablet, digital camera, maybe even a smart watch? And how often is it necessary to transfer pictures, documents or videos, between your devices? The inTouch technology developed by researchers from the VTT Research Center of Finland lets a ring, bracelet, or even a smart fingernail act as a conduit to transfer information between devices simply and securely – even when the devices are owned by different people.  Read More

A prototype lithium-ion battery, that incorporates the polymer

In their continuing efforts to increase the energy density of lithium-ion batteries, scientists have began looking at alternative materials for those batteries' electrodes – materials such as silicon. The problem is, electrodes swell and shrink as they absorb and release lithium ions, causing them to break down over time. This is particularly true of silicon, which is brittle by nature. Now, however, scientists have developed a conductive elastic polymer coating for those electrodes, that heals its own cracks after each use.  Read More

The Gabotronics Oscilloscope Watch is a testlab on your wrist (Photo: Gabotronics)

What do you wear on your wrist, is one-third the size of a deck of cards, and helps you troubleshoot your latest electronics project? The Oscilloscope Watch, of course. The Swiss army knife of electronics, this tiny test lab (or bulky watch) includes a 2-channel oscilloscope, frequency analyzer, arbitrary function generator, and a protocol sniffer. The price? An amazing US$125. Oh yes ... it also tells time.  Read More

The inFORM Dynamic Shape Display from MIT's Tangible Media Group allows users to interact with data with a minimum of physical barriers. It also allows users to virtually reach through a display screen, and manipulate physical objects that may be thousands of miles away. While the current version of inFORM has very limited spatial resolution, watching it in action gives one a strong impression of the potential of such devices.  Read More

Coin stores and provides access to electronic versions of your cards

Although things like NFC-enabled smartphones are making this less of an issue, the fact is that most of us still carry around a wallet full of credit, debit, loyalty or other cards that we routinely have to rifle through. That's why the Coin was invented. It's a single card-shaped device, on which all your other cards can be stored and accessed electronically.  Read More

QU-BD's One Up 3D printer can print with a minimu layer height of 50 microns

The home 3D printing revolution has picked up pace in recent times with printers such as the MakiBox and Buccaneer making 3D printing increasingly more affordable. Although not as cheap as the homemade LEGObot, the QU-BD One Up has taken the title as the world's cheapest production-ready 3D printer with a price tag of under US$200.  Read More

Over a year ago, Pensa Labs caught our attention with its impressive DIWire Bender, a small machine that bends thick wires into elaborate 3D shapes by following simple vector drawings. Since then, the company has been refining the wooden prototype we saw before into a sleek fabrication device that's fit for consumers. The result is a more compact, easier-to-use DIWire that can turn pieces of wire into creative 3D sculptures while sitting comfortably on a desktop.  Read More

Georgia Tech's printed circuit technique could make it cheaper and faster for professional...

Researchers at Georgia Tech have developed a new technique to print advanced, ink-based electrical circuitry on a desktop printer. After about US$300 in equipment costs, the researchers were able to print arbitrary-shaped circuits on resin-coated paper, PET film, and glossy photo paper with silver nanoparticle ink.  Read More

The five-cell metamaterial array developed by Duke engineers that converts stray microwave...

Joining the ranks of devices designed to harvest energy from ambient electromagnetic radiation comes an electrical circuit from researchers at Duke University that can be tuned to capture microwave energy from various sources, including satellite, sound or Wi-Fi signals. The researchers say the device converts otherwise lost energy into direct current voltage with efficiencies similar to that of current solar cells.  Read More
