Silicon polymer and battery used for the research

If you see a group of scientists playing with a blob of Silly Putty, they might not be goofing off, they may be working on a technological breakthrough. That turned out to be the case with researchers at the University of California, Riverside Bourns College of Engineering , who have developed a way to use an ingredient in Silly Putty to improve lithium-ion battery life between charges by three times the industry standard.  Read More

An international team of researchers has developed a supercapacitor composed of graphene and carbon nanotubes that is claimed flexible enough to be woven into clothing and potentially powerful enough to offer a real alternative to batteries for use in portable devices. Capable of being charged and discharged in excess of 10,000 cycles, the new supercapacitor also promises to be significantly lighter, faster to charge, and more robust than current battery technology.  Read More

The new chips could make thermal imagers standard issue for soldiers and police officers

Technological advances aren't just about making new devices. Many times it's more a matter of taking an existing device and improving on it. A case in point is Raytheon’s work on a new thermal imaging chip that the company says will find so many applications due to it being so small and cheap, that it may make the humble flashlight obsolete.  Read More

'Juanita Knits the Planet' found its way onto the hair not for its compelling narrative ar...

Advances in technology have given rise to an abundance of ways to share our stories. There's messaging services for the short and sharp, blogging platforms for the long-winded and, as it happens, single strands of human hair for microscopic comic strips. Created for the Exceptional Hardware Software Meeting (EHSM) in Germany next month, "Juanita Knits the Planet" is the world's smallest comic strip, detailing a day in the life of Juanita, a ten micron-tall girl-turned-robot.  Read More

A mock-up of the virtual keyboard system in use

We've been hearing about virtual keyboards for several years now, and they usually take the form of a keyboard template that's projected onto a flat surface. A team at Sweden's Mälardalen University, however, is developing something a little different. It's a system that combines a pair of bracelets with a wearable device such as Google Glass, to create a virtual keyboard that only its user can see.  Read More

The metal coil lighter provides enough heat to light a candle, paper or cigarette without ...

The latest iPhone multi-tool case to find its way to the world of crowd funding, the Hangout Case, offers three pocket-essential functions: protecting your iPhone, popping a bottle, and lighting a cigarette or fire. It also has a tripod screw mount.  Read More

The Mobile Authentication via Retina Scanner (MARS) prototype is compact and portable (Pho...

Retinal scans have a lot going for them as a form of identification. You can’t forget your retinas, they're unique, they’re a lot harder to steal than passwords, and Captain Kirk uses them. The problem is, the technology needed to run a reliable retinal scan is often bulky, expensive, and hard to use. Scientists at the Dresden-based Fraunhofer Institute for Photonic Microsystems (IPMS) have shrunk down retinal scanning technology in the hopes of making retinal scans a more widespread identification technology.  Read More

A group of engineers at Stanford have developed an iPad-sized, highly power-efficient way of simulating a million neurons and billions of synapses for as low as US$400. The advancement could both help our understanding of the brain and help develop a new generation of bionic limbs that are controlled by the patient's brain in real time with no effort at all.  Read More

Rice University postdoctoral researcher Yang Yang holds an energy storage unit with the be...

Researchers at Rice University have created an ultra-thin, high-performance flexible battery that is lithium-free, only a hundredth of an inch thick, and also doubles as a supercapacitor. The technology could find use in mobile and wearable electronics such as smartphones and fitness bands.  Read More

KAIST's DCRS prototype turns a LED television on at a 5-meter distance (Photo: KAIST)

Researchers at the Korea Advanced Institute of Science and Technology (KAIST), have developed a wireless charging system that can charge around 40 smart phones at a time, from a distance of 5 meters (16 ft). While we've examined numerous wireless charging systems, even one that transmits power to up to 9 m (30 ft), KAIST's prototype can power multiple devices within its range. It can deliver enough electrical juice, the scientists claim, to power many larger devices like fans, TVs and computers, simultaneously.  Read More
