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

ALARMclock is an alarm clock capable of displaying a lot more information than just the ti...

ALARMclock might look like a simple wooden alarm clock, but its meek exterior hides its true raison d'etre, which is to energize each morning by shocking users awake with facts and figures highlighting the harsh realities of life.  Read More

The DacMagic XS USB headphone amp from Cambridge Audio

It doesn't seem too long ago that a quality headphones amplifier was the size of a chunky paperback novel, and would occupy so much space in a laptop bag that it would probably get left behind more often than not. Now the UK's Cambridge Audio has managed to squeeze a high-end digital-to-analog (DAC) converter and headphone amp into a device that's smaller than a matchbox.  Read More

The MT840UHD MultiTaction Cell Display from MultiTouch Ltd

Only a few weeks after attendees at the annual developer conference of Finland's MultiTouch Ltd got a first look at the company's latest MultiTaction monster, it's gone up for pre-order. Currently a working prototype, the new 84-inch unit is claimed to be the world's first fully integrated, 4K resolution interactive display.  Read More

A new optical disc uses QR codes etched in tungsten to achieve extreme levels of heat resi...

A researcher at the University of Twente in the Netherlands has developed a new optical memory disc out of tungsten and silicon nitride that he says could store data safely for extremely long periods of time – up to a billion years.  Read More

A newly developed silicon supercapacitor could allow for the seamless integration of energ...

A team of researchers at the Vanderbilt University in Nashville, Tennessee has designed a supercapacitor made primarily of silicon that has shown much improved power density over its commercially available alternatives. The advance could allow for interesting integration of battery technology in everyday electronics, from solar cells to smartphones.  Read More

A new design for a semi-transparent plastic solar cell may be an important step toward the...

Researchers at the non-profit Institute of Photonic Sciences (ICFO) have created a new design for an organic solar cell that retains good efficiency while being flexible, thin, and almost completely transparent. Put together, these characteristics may make the cells an ideal candidate for building-integrated photovoltaics.  Read More

Aluminum studs on top of a PV panel could boost the efficiency of any solar cell design (I...

A team of researchers at Imperial College London has found that attaching an array of cylindrical aluminum studs on top of a solar cell can dramatically improve the amount of light trapped inside its absorbing layer, leading to electrical current gains as high as 22 percent.  Read More

The TAZ 2 sees the addition of an LCD screen and SD card slot to enable the printing of ob...

Aleph Objects, Inc., maker of the TAZ 3D printer through its LulzBot brand, has released the latest addition to its line of Libre Hardware printers. While bearing a strong resemblance to its predecessor that Gizmag reviewed earlier this month, the TAZ 2 boasts some improvements designed to solidify the printer’s structure and give it standalone functionality.  Read More

Innovation is all about putting on the proverbial thinking cap. Now engineers are vying to produce an actual thinking cap – at least one that can measure the most rudimentary signals of thought. The US Department of Defense is pushing for the development of cheap, wearable systems that can detect the brain waves of people and display the data on smartphones or tablets.  Read More
