Gallium nitride transistors enabled the compact design of this 2090 lumen retrofit LED lam...

Although known for long life and low energy consumption, the LED uses a DC power supply, or driver, to overcome its sensitivity to current fluctuations, and it’s the high-frequency, high-speed switching transistors in this driver that’s made the LED so costly for use in large-scale commercial applications dominated by fluorescent and incandescent lighting. But that’s about to change. Fraunhofer researchers are developing a new, more economical means of making the high-performance gallium nitride transistors needed for the LED’s high-efficiency driver.  Read More

hereO has announced a new GPS watch for tracking children

Part of being a kid is playing outside and exploring, so it's impossible to keep an eye on your children at all times. With this in mind, GPS tracking for kids has become increasingly popular. The hereO watch is the latest GPS tracking device aimed at providing parents with peace of mind.  Read More

Microscope photo of tungsten diselenide samples connected to electrodes

Graphene, the two-dimensional lattice of carbon atoms, may be the wonder material du jour, but ultrathin layers of other elements are also proving to be an exciting area of research. One-atom-thick sheets of germanium and tin have shown potential as semiconductors and a topological insulators respectively, and now ultrathin layers of tungsten and selenium have been used to create a diode that could be used in ultrathin, flexible, semi-transparent solar cells.  Read More

Space Replay is a floating sphere that records and replays the sounds around it

A floating sphere called Space Replay has been created that explores unusual sound signatures from transitional public spaces, moving around its space and replaying the sounds it picks up after a short delay.  Read More

Pioneer's DJE-2000 (left) and DJE-1500 (right) inner-ear headphones for DJs

It's not always practical for gigging DJs to wrap a pair of hefty cans around their heads when selecting or preparing tracks on a portable music player, smartphone or tablet, but even high-end earbuds might not cut the mustard when it comes to the specific audio needs of today's digital pancake turner. Pioneer's Professional Sound and Visual Division has developed some enclosed inner-ear headphones specially tuned for mixing and playing on the move.  Read More

This colorful American flag is in reality a functional  and transparent solar cell (Photo:...

A beautiful stained glass installation, a colorful billboard, or rows of windows on an office building ... all as electricity-generating solar cells? New research at the University of Michigan gives a method for creating such transparent and colorful solar cells using a hybrid silicon/organic composition, and furthermore avoids some of the problems of previous colored and transparent solar cells.  Read More

One of four tactile demos on Fujitsu's prototype haptic sensory tablet

Many smartphone or tablet users will already be familiar with receiving vibration feedback when typing on a virtual keyboard, but, though better than nothing, it's not particularly convincing. There have been attempts to make sensory feedback from touchscreens more realistic using electrostatic force, for example, or even creating the sensation of physical buttons by pushing liquid into prearranged tactile pixels, but Fujitsu is claiming to break new ground with its prototype haptic sensory tablet.  Read More

Lulzbot TAZ 3 printers line the cluster room four-deep and three-high

Aleph Objects, maker of the LulzBot line of 3D printers, recently made the switch to a new facility in Colorado, big enough to meet its expanding production needs and designed to add more injection-molded and laser-cut parts to the printers. I toured the massive cluster of 135 operating 3D printers, asked about AO’s upcoming plans for not only new printers but other hardware, learned how customers and community drive innovation, and met a fascinating LulzBot client who’s using the Open Source/Libre technology to jumpstart his vision of the future. If you’ve ever wanted to see 135 3D printers in action simultaneously, look no farther.  Read More

The Atmos system delivers discrete signals to up to 128 simultaneous and lossless audio st...

The name Dolby Laboratories has long been associated with innovative and world-leading sound reproduction. Its latest creation, Atmos, has come at the perfect time to augment the unprecedented immersive experience of big screen 3D stereoscopic images. Since it was first installed in the Dolby Theatre in Hollywood for the release of Pixar’s Brave in 2012, Atmos technology has been embraced by leading film makers and rolled out in hundreds of cinemas out around the globe, launching movie soundtracks into the world of 3D. Gizmag recently attended a demonstration of the Dolby Atmos system to hear what all the fuss is about and speak to the experts about the impact the new technology is having on the way movies are made.  Read More

Lickestra is a musical performance that uses ice cream as the instrument

Playing with your food is generally frowned upon, but very little is said about playing music with your food. Artists Emilie Baltz and Carla Diana are exploring exactly that concept. Their work Lickestra is a musical performance in which ice cream is used as the instrument.  Read More
