Action cams have become a ubiquitous part of ski resorts everywhere. They're great for catching your best on-slope moments and sharing them with the world, but they can be a little bit bulky and awkward to use with gloves. The Zeal iON goggles solve this problem by integrating the HD camera right into the goggle frame. Read More

A new platform for wearable electronics, known as the FLORA, was announced by its creators Adafruit Industries on Friday. Essentially a small, round, fabric-friendly circuit board that looks a little like a flower, the FLORA will, when ready, be launched with a variety of accessories and software. These will include, we gather, controllers for iPhone, iPad and Android hardware. The FLORA is ripe for wearable DIY electronics projects: announced modules include Bluetooth, GPS, 3-axis accelerometer, compass, and, intriguingly, OLED. Read More

The world's narrowest silicon wires with a cross section of a mere four atoms by one atom have been created by a team of developers from the University of New South Wales, the University of Melbourne and Purdue University. The wires are fully functioning, with current-carrying capacity equivalent to that of a microprocessor's copper cable, despite being 20 times thinner - and 10,000 times narrower than a human hair.

A hard material is impregnated with microcapsules that burst when the material cracks, releasing a stored liquid that hardens on contact with the air, thus repairing the crack ... it’s a system that we’ve recently seen used in a number of applications, including self-healing concrete and polymers. Now, a research team from the University of Illinois is applying it to electronics. They have already created a system that automatically restores conductivity to a cracked circuit in just a fraction of a second. Read More

Although we may think of smartphones as being like tiny desktop computers, they do have at least one key difference – in order to save battery power, many of their functions are hardwired into highly-efficient dedicated processors, instead of taking the form of software. Because smartphones perform so many functions, however, not all of them can be hardwired. As a result, designers of mobile devices must decide which functions will be handled by software, and which by hardware. Computer scientists from MIT have recently devised a system that should make those designers’ jobs a lot easier – if they’re willing to adopt it. Read More

There's no shortage of cord management solutions out there, but Pod Power promises to deliver a level of versatility that's over and above the norm. At its most basic Pod Power is a 15 foot (4.5 meter) long extension cord, but rather than having on outlet at the end, you get five pods at 3-foot intervals. Each pod has its own standard three-prong outlet and a keyhole for easy mounting on the wall, floor or ceiling. Read More

By now, we’re all fairly used to electronic devices such as smartphones, which can act as a mobile phone, computer, camera and navigation unit all at once. These devices, while multi-functional, still use different hard-wired electrical circuits for their different functions. Thanks to research being carried out at Chicago’s Northwestern University, however, all those functions may one day be able to utilize the same physical piece of electronic material – the electrical current would simply be “steered” through it differently, depending on what was needed. This means that a single section of the material could act as a resistor, rectifier, diode or transistor, as instructed by a computer. Read More

Wearable electronics generally take the form of clothing embedded with electronics or miniature electronic devices that can be worn close to the body for purposes such as medical monitoring and communications. Now engineers have developed a device that places electronic components onto an ultra-thin skin-like patch that can be mounted directly onto the skin, paving the way for skin-mounted electronics that could be used for sensing, medical diagnostics, communications and human-machine interfaces.

As you sit there reading this story you’re surrounded by electromagnetic energy transmitted from sources such as radio and television transmitters, mobile phone networks and satellite communications systems. Researchers from the Georgia Institute of Technology have created a device that is able to scavenge this ambient energy so it can be used to power small electronic devices such as networks of wireless sensors, microprocessors and communications chips.
