Metallized paper makes for flexible, foldable supercapacitors

If batteries are the marathon runners of the energy storage world, then supercapacitors are sprinters: great for short bursts of power but not so great long-term. Now engineers from Georgia Tech and Korea University have developed a new supercapacitor that's designed to store more energy for longer – and it's made out of ordinary paper, meaning it's flexible enough to power wearable electronics...

Rotational smartwatch keyboard channels the rotary phone

Smartwatches may not have found the immediate success that manufacturers were hoping for, and that might be due in part to the smaller screen making some functions, like entering text, more fiddly than they'd be on a phone. Now a team from Stony Brook University has developed a rotational keyboard that allows users to pick letters from a ring around the screen, like an old rotary phone...

"Ion highway" electrodes drive development of batteries that charge in seconds

Supercapacitors can charge and release energy much faster than batteries, but they can't store as much. Now a team at Drexel University has used the two-dimensional material MXene to develop a new type of electrode, combining the capacitance of a regular battery with the speed of a supercapacitor, which could lead to devices that recharge in a matter of seconds...

Flexible, self-healing wearable device harvests energy from body heat

Wearable electronic devices are starting to save some battery power by harvesting an energy source that's right underneath them: human body heat. But while flexible devices are more comfortable to wear, they aren't quite as effective at soaking up that heat as rigid ones. Now a team from North Carolina State University has developed a system using liquid metal components, making it flexible, efficient and even self-healing...

NASA plans probe of mysterious ice giants in the outer Solar System

Uranus hasn't had a visitor since 1986 and Neptune's been neglected since 1989, but NASA has begun to outline its plans to return to the ice giant planets on the fringes of our Solar System. In preparation, the agency conducted a study to determine the scientific focus of these potential missions, the kinds of instruments needed and the logistics of how the spacecraft would get there...

Fern-leaf inspires electrode for high density solar energy storage

Solar cells are constantly getting better at collecting energy from sunlight, but their ability to store it isn't improving quite as fast. Made from graphene and with a fern-inspired fractal structure, engineers at RMIT University have developed a new prototype electrode that could enable solar harvesting and storage systems that are thin, flexible and have high capacity...

Thin, built-in batteries to free up valuable space on CubeSats

Real estate is a valuable commodity aboard a CubeSat, a compact satellite about the size of a shoebox, so the smaller each component can be made, the better. To that end, scientists at NASA's Kennedy Space Center and the University of Miami are developing a thin, solid-state battery, which could not only save space for more important instruments aboard satellites, but also provide power on other planets, in cars or within the walls of a home...

Can retro arcade games make a wrist-worn comeback?

Between smartphones, tablets, and handheld gaming systems like the 3DS and the upcoming Nintendo Switch, killing time on bus rides has never been easier. But soon you might be able to fill those hours with some classic Atari arcade games as well – provided you don't mind playing them one-handed on a tiny smartwatch screen. ..

Asus’s ZenFone AR can both Daydream and Tango

Augmented reality (AR) has the potential for some really cool experiences, as we've seen with Microsoft's vaporware-ish Hololens and the (just-barely-AR) Pokémon Go, but it hasn't yet hit the mainstream. Tango, Google's AR platform for mobile devices, might help that along, and now Asus has unveiled the ZenFone AR, which works with Tango as well as Google's Daydream VR headset...

Waterproof clip-on brings NFC payments to regular watches

Both Apple and Samsung have their own NFC-based payment systems, activated by tapping a phone or smartwatch to a card reader or terminal. Now, Sydney startup Inamo has developed the Curl, a wearable, waterproof device containing a prepaid NFC chip that can bring tap-and-go payments to any regular watch, fitness tracker or piece of jewelry...

Nightingale Sleep encourages slumber under a white noise "sound blanket"

Pitch black darkness and silence may help some people drift off at night, but others fall asleep better with music, TV or a fan on in the room. For the latter group, a white noise machine or app can be a handy bedside companion, but Cambridge Sound Management claims it has a better option with the Nightingale, a new Internet of Things-enabled system that uses two speakers in a room to create a "sound blanket" that is designed to blend into the background and block disruptive sounds...

Sweden’s Uniti short-range city EV successfully navigates crowdfunding route

Lessening range anxiety is a priority for many electric vehicle manufacturers, but others are steering into the skid with small EVs designed for short-range city driving, like the Renault Twizy and the Microlino. Joining them is the Swedish startup Uniti, which has just hit its crowdfunding goal to develop a prototype of its own little electric city car by the end of 2017...

Intel fashions stress-sensing glasses and a belt-based projector

Between fitness trackers, jackets with built-in Wi-Fi, and watches packed with enough gadgets to make James Bond jealous, fashion and technology can be strange bedfellows. At a runway show for Paris Fashion Week, designer Hussein Chalayan has teamed up with Intel to create a high-tech outfit straight out of an 80s sci-fi movie, complete with glasses that sense stress and a belt that projects live images of that data onto a wall...
