This new battery charges 10 times faster than the one in your smartphone

Posted by in categories: energy, mobile phones

Chinese technology company Huawei has announced that its latest prototype battery fills up with power 10 times quicker than the ones in current smartphones. Huawei has been showing off the technology at the 56th Battery Symposium in Japan this week, where a 3,000mAh pack reached a 48 percent charge in just 5 minutes.

The lithium-ion batteries inside smartphones, tablets, and other similar gadgets have two main sections: an anode and a cathode. Electrons move from one section to the other while our devices are in use, and then back in the opposite direction as they are recharged.

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.”

Breakthrough! Glasgow scientists discover a cheap way to produce the wonder material graphene

Posted by in categories: biotech/medical, cyborgs, materials, mobile phones

It has been hailed as a wonder material set to revolutionise everyday life, but graphene has always been considered too expensive for mass production – until now.

Scientists at Glasgow University have made a breakthrough discovery, allowing graphene to be produced one hundred times more cheaply than before, opening it up to an array of new applications.

First isolated in 2004, the miracle material can be used in almost anything from bendable mobile phone screens to prosthetic skin able to provide sensation.

Samsung is making a flip phone that looks like it’s from 2004

Posted by in category: mobile phones

With a glass and metal design reminiscent of the Galaxy S6, it could prove pretty popular.

It’s actually quite difficult to buy a phone these days that isn’t a buttonless smartphone — leaving people who prefer a physical keyboard (they still exist, as the Blackberry Priv shows) without many options.

The market for this phone might be fairly niche, but if it satisfies users’ nostalgia and actually works it could be a success.

Graphene Could Give Us Sleek Night Vision Sensors

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

Because of its unique chemical and physical properties, graphene has helped scientists design new gadgets from tiny computer chips to salt water filters. Now a team of researchers from MIT has found a new use for the 2D wonder material: in infrared sensors that could replace bulky night-vision goggles, or even add night vision capabilities to high-tech windshields or smartphone cameras. The study was published last week in Nano Letters.

Night vision technology picks up on infrared wavelengths, energy usually emitted in the form of heat that humans can’t see with the naked eye. Researchers have known for years that because of how it conducts electricity, graphene is an excellent infrared detector, and they wanted to see if they could create something less bulky than current night-vision goggles. These goggles rely on cryogenic cooling to reduce the amount of excess heat that might muddle the image. To create the sensor, the researchers integrated graphene with tiny silicon-based devices called MEMS. Then, they suspended this chip over an air pocket so that it picks up on incoming heat and eliminates the need for the cooling mechanisms found in other infrared-sensing devices. That signal is then transmitted to another part of the device that creates a visible image. When the researchers tested their sensor, they found that it clearly and successfully picked up the image of a human hand.

Asus says it’s building an augmented reality headset to release in 2016

Posted by in categories: augmented reality, mobile phones, virtual reality

Taiwanese PC manufacturer Asus says it’s building an augmented reality device and aims to release it next year. According to a report from CNET, Asus CEO Jerry Shen confirmed the plans during an earnings call on Wednesday, arguing that augmented reality or AR will be more useful than virtual reality. “You can make a real setting meld together with yourself and the AR portion,” said Shen. “Internally, we are talking about how to prepare.”

Unlike VR, augmented reality doesn’t show you a completely fabricated view, but instead overlays digital elements onto the real world. The current frontrunner in this nascent field is Microsoft’s HoloLens, which the company has shown off in a range of impressive demos. However, the HoloLens is hampered by a number of problems, including bulkiness, constrained viewing angles, and a high price tag, with Microsoft releasing a $3,000 HoloLens developer kit in the first quarter of 2016. (By comparison, Samsung’s Gear VR, a virtual reality headset powered by the company’s smartphones, became available for preorder this week for just $99.) Asus has previously hinted that it might build its own version of the HoloLens, but as a company best known for its budget laptops, tablets, and smartphones, we wouldn’t expect it to match Microsoft’s price.

Despite the lack of unknowns surrounding Asus’s announcement, it’s still interesting to see a company align itself with augmented, rather than virtual, reality. The Verge’s Adi Robertson has argued that the complete immersion of VR makes it difficult for multitasking, and that augmented reality, by comparison, is more practical. Asus apparently agrees. “We think AR will be very important for people’s lives,” said Shen according to CNET. “It should be next year when we come out with a product.”

Researchers have designed a battery that’s 90 percent more efficient than lithium-ion

Posted by in categories: electronics, energy, mobile phones

Smartphones, laptops, and all manner of electronics have advanced by leaps in bounds over the past few decades, but an essential component of most of them — the battery, or more precisely the lithium-ion battery — hasn’t. The technological remnant of the mid-’90s has a tendency to degrade and isn’t particularly efficient, which is why scores of researchers have spent years pursuing alternatives. Until now, though, practical limitations — i.e., physical dimensions and mass manufacturing constraints — have permanently relegated many to laboratories. But a new design, a refinement of so-called lithium-air design by scientists at the University of Cambridge, looks to be one of the most feasible yet.

Lithium-air (Li-air) batteries have been around for a while — chemist K. M. Abraham is credited with developing the first rechargeable variant in 1995 — but they’ve never been considered very practical. That’s because they use carbon as an electron conductor instead of the metal-oxide found in conventional Li-ion batteries, and generate electricity from the reaction of oxygen molecules and lithium molecules, a process which leads to the production of electrically resistant lithium peroxide. As the lithium peroxide builds up, the power-producing reaction diminishes until it eventually ceases completely.
