A prosthetic that restores the sense of where your hand is

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

Researchers have developed a next-generation bionic hand that allows amputees to regain their proprioception. The results of the study, which have been published in Science Robotics, are the culmination of ten years of robotics research.

The next-generation bionic hand, developed by researchers from EPFL, the Sant’Anna School of Advanced Studies in Pisa and the A. Gemelli University Polyclinic in Rome, enables amputees to regain a very subtle, close-to-natural sense of touch. The scientists managed to reproduce the feeling of proprioception, which is our brain’s capacity to instantly and accurately sense the position of our limbs during and after movement – even in the dark or with our eyes closed.

The new device allows to reach out for an object on a table and to ascertain an item’s consistency, shape, position and size without having to look at it. The prosthesis has been successfully tested on several patients and works by stimulating the nerves in the ’s stump. The nerves can then provide to the patients in real time – almost like they do in a natural hand.

This Spider Has Been Dead For 110 Million Years, But Its Eyes Still Shine in The Dark

Posted by in category: cyborgs

Soft, squishy, ancient spiders are hard to investigate — they don’t fossilise as easily as bones or exoskeletons. So you can imagine how excited researchers were to find 10 brand new spider fossils in a relatively unexplored area called the Jinju Formation.

The Jinju Formation is a geological area of South Korea from the Mesozoic era, between 252 and 66 million years ago. This new spate of fossils, which researchers from the Korea Polar Research Institute and the University of Kansas found in shale, has increased the number of known spiders in the Jinju Formation from just one to a whopping 11.

But two of these spider finds were even more exciting than the rest – their eyes still reflected light 110 million years after they died.

Carbon Nanotube Ribbons Could Give Superman a Run for His Money

Posted by in categories: cyborgs, economics, nanotechnology

stretchy nanotubesLighter than air! Stronger than steel! More flexible than rubber! No, it’s not an upcoming superhero flick: It’s the latest marvelous formulation of carbon nanotubes–at least as reported by the creators of the new super-material. Researchers working on artificial muscles say they’ve created nanotech ribbons that make our human muscles look puny by comparison. The ribbons, which are made of long, entangled 11-nanometer-thick nanotubes, can stretch to more than three times their normal width but are stiffer and stronger than steel… They can expand and contract thousands of times and withstand temperatures ranging from −190 to over 1,600 °C. What’s more, they are almost as light as air, and are transparent, conductive, and flexible [Technology Review].

The material is made from bundles of vertically aligned nanotubes that respond directly to electricity. Lengthwise, the muscle can expand and contract with tremendous speed; from side-to-side, it’s super-stiff. Its possibilities may only be limited by the imaginations of engineers. [The material’s composition] “is akin to having diamond-like behavior in one direction, and rubber-like behavior in the others” [Wired], says material scientist John Madden, who wasn’t involved in the research.

When voltage is applied to the material, the nanotubes become charged and push each other away, causing the material to expand at a rate of 37,000 percent per second, tripling its width. That’s 10 times as far and 1000 times as fast as natural muscle can move, and the material does so while generating 30 times as much force as a natural muscle [IEEE Spectrum]. The researchers put together a video to illustrate the concept, and will publish their work in Science tomorrow.

Doctors Wired a Prosthetic Hand Directly Into a Woman’s Nerves

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

In a world first, doctors in Sweden say they’ve wired a prosthetic hand directly into a woman’s nerves, allowing her to move its fingers with her mind and even feel tactile sensations.

The hand is an enormous step up from existing prostheses, which often rely on electrodes placed on the outside of the skin — and it could herald a future in which robotic devices interface seamlessly with our bodies.

Superhuman Skin Senses Sound Waves and Magnetic Fields

Posted by in categories: biotech/medical, cyborgs, nanotechnology, wearables

Researchers have developed a new kind of sensor designed to let artificial skin sense pressure, vibrations, and even magnetic fields. Developed by engineers, chemists, and biologists at the University of Connecticut and University of Toronto, the technology could help burn victims and amputees “feel” again through their prosthetic skin.

“The type of artificial skin we developed can be called an electronic skin or e-skin,” Islam Mosa, a postdoctoral fellow at UConn, told Digital Trends. “It is a new group of smart wearable electronics that are flexible, stretchable, shapable, and possess unique sensing capabilities that mimic human skin.”

To create the sensor for the artificial skin, Mosa and his team wrapped a silicone tube with a copper wire and filled the tube with an iron oxide nanoparticle fluid. As the nanoparticles move around the tube, they create an electrical current, which is picked up by the copper wire. When the tube experiences pressure, the current changes.
