This is the Audi of the future, and it looks like a computer mouse

Posted by in categories: computing, electronics, transportation

“I believe the children are our future,” philosopher Whitney Houston once opined. Well, if she was talking about car design, she wasn’t wrong.

OK, not ‘children’ exactly. But certainly students. Audi has today unveiled the results of its ‘Design Universe’ think-tank, in which young designers at four top universities have explored how the Audi of tomorrow might look.

Take the car above, as an example. It’s called the Audi Quantum, and was designed by a pair of students at the Scuola Politecnica di Design in Milan. Looks suitably futuristic, no? There are retina scanners that, um, scan the driver’s retina and configure the interior settings before he or she climbs in.

This new touchscreen material could see the end of daily smartphone charging

Posted by in categories: electronics, energy, materials, mobile phones

Scientists in the UK have invented a new type of touchscreen material that requires very little power to illuminate, offering up a cheap alternative to today’s smartphone and tablet screens, with vivid colours and high visibility in direct sunlight.

The team is already in talks with some of the world’s largest consumer electronics corporations to see if their new material can replace current LCD touchscreens in the next couple of years, which could spell the end for daily smartphone charging. “We can create an entire new market,” one of the researchers, Peiman Hosseini, told The Telegraph. “You have to charge smartwatches every night, which is slowing adoption. But if you had a smartwatch or smart glass that didn’t need much power, you could recharge it just once a week.”

Developed by Bodie Technologies, a University of Oxford spin-off company, the new display is reportedly made from a type of phase-change material called germanium-antimony-tellurium, or GST. The researchers are being understandably cagey about exactly how it’s made as they shop the technology around, but it’s based on a paper they published last year describing how a rigid or flexible display can be formed from microscopic ‘stacks’ of GST and electrode layers.

New ‘self-healing’ gel makes electronics more flexible

Posted by in categories: electronics, energy, materials

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a first-of-its-kind self-healing gel that repairs and connects electronic circuits, creating opportunities to advance the development of flexible electronics, biosensors and batteries as energy storage devices.

Although technology is moving toward lighter, flexible, foldable and rollable electronics, the existing circuits that power them are not built to flex freely and repeatedly self-repair cracks or breaks that can happen from normal wear and tear.

Until now, self-healing materials have relied on application of external stimuli such as light or heat to activate repair. The UT Austin “supergel” material has high conductivity (the degree to which a material conducts electricity) and strong mechanical and electrical self-healing properties.

No lens? No problem for FlatCam

Posted by in categories: computing, electronics, information science

How thin can a camera be? Very, say Rice University researchers who have developed patented prototypes of their technological breakthrough.

FlatCam, invented by the Rice labs of electrical and computer engineers Richard Baraniuk and Ashok Veeraraghavan, is little more than a thin with a mask that replaces lenses in a traditional camera.

Making it practical are the sophisticated computer algorithms that process what the sensor detects and converts the sensor measurements into images and videos.

World’s first cyber-plants fuse electronics with roses

Posted by in categories: electronics, materials

For the first time, scientists have created analogue and digital electronic circuits inside living plants, using the vascular system of living roses to build – or rather ‘grow’ – the central components of electronic circuits.

Researchers at Linköping University in Sweden merged numerous electrical components inside the roses, including wires, digital logic, and even display-based elements, thanks to a special polymer that’s capable of acting like a wire while still transporting organic material such as water and nutrients through the rose’s stem.

By successfully incorporating electronics into the living systems of plants, it’s hoped we’ll be able to find out much more about the chemical processes and pathways that make them function – and we could even learn to control and manipulate them.

Quantum entanglement achieved at room temperature in semiconductor wafers

Posted by in categories: computing, electronics, particle physics, quantum physics

Entanglement is one of the strangest phenomena predicted by quantum mechanics, the theory that underlies most of modern physics. It says that two particles can be so inextricably connected that the state of one particle can instantly influence the state of the other, no matter how far apart they are.

Just one century ago, was at the center of intense theoretical debate, leaving scientists like Albert Einstein baffled. Today, however, entanglement is accepted as a fact of nature and is actively being explored as a resource for future technologies including quantum computers, quantum communication networks, and high-precision quantum sensors.

Entanglement is also one of nature’s most elusive phenomena. Producing entanglement between particles requires that they start out in a highly ordered state, which is disfavored by thermodynamics, the process that governs the interactions between heat and other forms of energy. This poses a particularly formidable challenge when trying to realize entanglement at the macroscopic scale, among huge numbers of particles.

Moore Foundation Gives Stanford $13.5 Million To Build “Accelerator on a Chip”

Posted by in categories: biotech/medical, computing, electronics, mobile phones, particle physics, security

Today’s particle accelerators are massive machines, but physicists have been working on shrinking them down to tabletop scales for years. The Gordon and Betty Moore Foundation just awarded a $13.5 million grant to Stanford University to develop a working “accelerator on a chip” the size of a shoebox over the next five years.

The international collaboration will build on prior experiments by physicists at SLAC/Stanford and Germany’s Friedrich-Alexander University in Erlangen-Nuremberg. If successful, the prototype could usher in a new generation of compact particle accelerators that could fit on a laboratory bench, with potential applications in medical therapies, x-ray imaging, and even security scanner technologies.

The idea is to “do for particle accelerators what the microchip industry did for computers,” SLAC National Accelerator Laboratory physicist Joel England told Gizmodo. Computers used to fill entire rooms back when they relied on bulky vacuum tube technology. The invention of the transistor and subsequent development of the microchip made it possible to shrink computers down to laptop and cell phone scales. England envisions a day when we might be able to build a handheld particle accelerator, although “there’d be radiation issues, so you probably wouldn’t want to hold one in your hand.”

‘Power Over Wi-Fi’ named one of the year’s game-changing technologies

Posted by in categories: electronics, energy, internet

University of Washington engineers have developed a novel technology that uses a Wi-Fi router—a source of ubiquitous but untapped energy in indoor environments—to power devices.

The Power Over Wi-Fi (PoWiFi) system is one of the most innovative and game-changing technologies of the year, according to Popular Science, which included it in the magazine’s annual “Best of What’s New” awards announced Wednesday.

The technology attracted attention earlier this year when researchers published an online paper showing how they harvested energy from Wi-Fi signals to power a simple temperature sensor, a low-resolution grayscale camera and a charger for a Jawbone activity tracking bracelet.
