The lab prototype of the pizzicato knee-joint energy harvester

If you’ve ever worn a knee brace, then you may have noticed what a large change in angle your knee goes through with every step you take, and how quickly it does so. A team of scientists from the U.K.’s Cranfield University, University of Liverpool and University of Salford certainly noticed, and decided that all that movement should be put to use. The result is a wearable piezoelectric device that converts knee movement into electricity, which could in turn be used to power gadgets such as heart rate monitors, pedometers and accelerometers.  Read More

The Android-powered system is contained within a single backpack (Photo: Google)

Over the last few years, Google's specially-designed cars, trikes, trolleys and snowmobiles have brought interactive Street View technology to the cities and jungles of the world – but why stop there? The search giant recently unveiled the Street View Trekker, a hi-tech backpack-contained system that will bring Street View to those places that can only be reached on foot.  Read More

The LED-meisters at macetech LLC seized upon this week's Maker Faire to unveil an eye-catching pair of prototype "LED matrix shades" that light up in a variety of dynamic patterns. When the shades hit the market in six to eight weeks, users will be able to program patterns of their own, thanks to the Arduino-compatible electronics from which they're made. macetech's Garrett Mace gave Gizmag an exclusive insight into the development of the shades, which look like they've fallen through a portal from some future urban dystopia.  Read More

Vergence Labs' Social Video Electric Eyewear

There is a bandwagon just starting to roll containing various pairs of video-capable and augmented reality glasses. Google is currently in the driver's seat, but it's far from the only company working on ways to allow us all to record video from a first-person perspective and integrate what we see into our online lives. A case in point is Vergence Labs' Social Video Electric Eyewear.  Read More

While it can be nice to listen to motivating music while riding your bike, riding on the streets while wearing earbuds is ... well, crazy. In many places, it’s also illegal. One option is to wear non-sealing earHero earphones, which are claimed to allow both outside noise and music into the user’s ear canal. Another, however, is to attach some Otus Mini-Speakers to your helmet.  Read More

The QLOCKTWO W watch spells out the time in words

Japan’s Tokyoflash has made a name for itself with numerous weird and wonderful – or maybe baffling - ways to tell the time. Now, bringing to mind Homer Simpson’s quote of, “From now on Honey, we'll be spelling everything with letters,” when Marge is impressed by a house that has its street number spelled out with letters, German design agency Biegert & Funk is set to release a wristwatch that fancies things up by telling the time in words.  Read More

CordCrunchers can be worn around your wrist or neck

Headphone cords: they're far from the gravest problem facing mankind today, but much like the common cold, they persistently annoy with no end in sight. At least we have a new, non-prescription pill, in the form of CordCrunchers.  Read More

Fraunhofer's external transmitter, which is paired with an internal mobile generator

When it comes to implantable electronic devices such as pacemakers, biosensors or drug-delivery devices, there are a few options regarding power sources. While batteries could be used in some applications, doing so would require surgically replacing the implant when its battery runs out. Radio wave-based and inductive systems are instead often used, in which power is “beamed” to the device from a source outside the body. According to researchers from Germany’s Fraunhofer Institute for Ceramic Technologies and Systems, however, such systems often have a limited range, and are easily affected by factors such as location, position and movement. Instead, they’ve developed what they claim is a better, more versatile system.  Read More

Google's Project Glass hopes to deliver an augmented reality heads-up display

Google X (Google's futuristic technology development lab) has pulled back the curtain on Project Glass, its program to develop truly useful augmented reality "Google glasses." Project Glass aims to design and refine augmented reality technology to help a user explore and share their world armed with a wealth of relevant information - not at their fingertips, but rather at the end of their nose.  Read More

Conventional earphones can become a liability you are out and about on city streets by limiting your ability to hear approaching vehicles or other potential hazards. That’s where the earHero comes into play. It’s an earphone system designed not to block the ear canal so that users are still be able to hear what’s going on around them.  Read More
