Researchers create lithium-air battery that could be 10x more powerful than lithium-ion

Posted by in categories: chemistry, electronics, mobile phones, solar power, sustainability, transportation

A new lithium-air battery created by researchers at the University of Cambridge points the way to the ultimate battery packs of the future, its makers say. With a very high energy density, more than 90 percent efficiency and the capability for more than 2,000 recharge cycles, the new test battery could prove an important stepping stone in the development of this essential technology.

If you’re getting tired of announcements about breakthroughs in battery technology, that’s understandable: as they’re so essential to modern life, many teams of scientists are busy working on the problem around the clock, but it’s an incredibly complex area of chemistry. Any new battery has to improve on what we already have, be safe to use in consumer gadgets, and be commercially viable enough to be affordable for manufacturers.

Those are difficult targets to hit, and that’s why many ‘miracle’ batteries have since fallen by the wayside – once the initial lab work is done, proving concepts and scaling up production is very difficult to get right. The potential rewards are huge though, not just for smartphones but for electric cars and solar power, where batteries are essential for storing energy to use when the sun isn’t shining.

New artificial skin can detect pressure and heat simultaneously

Posted by in categories: computing, cyborgs, materials, mobile phones, robotics/AI

A team of researchers with Ulsan National Institute of Science and Technology and Dong-A University, both in South Korea, has developed an artificial skin that can detect both pressure and heat with a high degree of sensitivity, at the same time. In their paper published in the journal Science Advances, the team describes how they created the skin, what they found in testing it and the other types of things it can sense.

Many scientists around the world are working to develop , both to benefit robots and human beings who have lost skin sensation or limbs. Such efforts have led to a wide variety of artificial skin types, but until now, none of them have been able to sense both pressure and heat to a high degree, at the same time.

The new artificial skin is a sandwich of materials; at the top there is a meant to mimic the human fingerprint (it can sense texture), beneath that sit sensors sandwiched between . The sensors are domed shaped and compress to different degrees when the skin is exposed to different amount of pressure. The compression also causes a small electrical charge to move through the skin, as does heat or sound, which is also transmitted to sensors—the more pressure, heat or sound exerted, the more charge there is—using a computer to measure the charge allows for measuring the degree of sensation “felt.” The ability to sense sound, the team notes, was a bit of a surprise—additional testing showed that the artificial skin was actually better at picking up sound than an iPhone microphone.

Mind Control Device Alters Emotions on Demand

Posted by in categories: electronics, finance, mobile phones, neuroscience

Think of all the possibilities!


braincontrolMind control has been a topic of many great suspense and science fiction movies until recent. Now, an emotion altering device that will work in conjunction with a smart phone app is now being developed by Thync, and is slated for release to the public in 2015.

Thync announced on Oct. 8 that it’s raised $13 million from financial contributors to develop technology combining neuroscience and consumer electronics.

Are these artificial limbs better than the real thing?

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

These people have got a leg — or an arm — up on the future.

Thanks to the latest advancements in medical science, amputees are becoming part robot, with awe-inspiring artificial limbs that would make Luke Skywalker jealous.

These new limbs come armed with microprocessors and electrodes that sense muscle movement. Others can be controlled by a smartphone app. People missing limbs often tried to hide their prosthetics, but these New Yorkers are showing them off with pride.

Acer is launching an electric all-terrain vehicle

Posted by in categories: electronics, mobile phones, transportation

Acer might be better-known for its range of laptops, tablets, phones, and similar consumer electronics, but it has quietly lifted the lid on a brand-new product line — an electric, all-terrain vehicle (eATV).

The Taiwanese tech titan unveiled the eATV “X Terran” (presumably that’s not meant to be ‘Terrain’) prototype at the eCarTech conference in Munich last week, but the company didn’t reveal too many details. We have, however, now obtained some photos of the vehicle.

See how InVisage’s HDR sensor will improve smartphone filmmaking

Posted by in categories: media & arts, mobile phones, transportation

InVisage filmed in challenging, bright sunlight conditions to test the dynamic range, and shot fast moving subjects (RC race cars) to show off the global shutter. The resulting footage (below) is surprisingly cinematic, considering that the sensor is smartphone sized. (It’s also a bit soft, which the company chalked up to the sensor being an early prototype.) The tech looks intriguing, though the level of hype in the press release and making-of film is a bit over-the-top. Still, if it can be refined further — perhaps by a sensor company like Sony — it could result in strikingly better smartphone and camera images in the not-too-distant future.

Scientists Connect Brain to a Basic Tablet—Paralyzed Patient Googles With Ease

Posted by in categories: biotech/medical, mobile phones, neuroscience

That was the year she learned to control a Nexus tablet with her brain waves, and literally took her life quality from 1980s DOS to modern era Android OS.

A brunette lady in her early 50s, patient T6 suffers from amyotrophic lateral sclerosis (also known as Lou Gehrig’s disease), which causes progressive motor neuron damage. Mostly paralyzed from the neck down, T6 retains her sharp wit, love for red lipstick and miraculous green thumb. What she didn’t have, until recently, was the ability to communicate with the outside world.
