SmartHand brings movement AND touch to amputees

By




Scientists have successfully wired a state-of-the-art artificial hand to existing nerve endings in the stump of a severed arm. Its creators say the device, called “SmartHand,” resembles a real hand in function, sensitivity and appearance. In order to develop such an intelligent artificial prosthetic hand with all the basic features displayed by a real one, the SmartHand team integrated recent advances in nanobioscience, cognitive neuroscience and information technologies.
The artificial SmartHand, built by a team of top European Union and Israeli scientists, features four electric motors and 40 sensors that are activated when the SmartHand touches an object, not only replicating the movement of a human hand, but also providing the wearer with a sensation of feeling and touch.
Robin af Ekenstam of Sweden, the project's first human subject, has not only been able to complete extremely complicated tasks like eating and writing, he reports he is also able to "feel" his fingers once again.
"I am using muscles which I haven't used for years. I grab something hard, and then I can feel it in the fingertips, which is strange, as I don't have them anymore. It's amazing," Ekenstam told a television interviewer. Thankfully the SmartHand will belong to Ekenstam as long as he wishes. While the prototype looks very "bionic" now, in the future SmartHand scientists plan to equip it with artificial skin that will give the brain even more tactile feedback. The researchers will also study amputees equipped with the SmartHand to understand how to improve the device over time.
Although the SmartHand project focused on hands, the researchers say they could also have built bionic legs to be wired to the brain. The team first chose to build a hand, however, because of its unique challenges. "The fingers in the hand are the most complex appendages we have," Prof. Shacham-Diamand observes. "The brain needs to synchronize the movement of each digit in a very complicated way."
The SmartHand project is a collaboration between Tel Aviv University (Israel), ARTS Lab, Scuola Superiore Sant'Anna (Italy), Aalborg University (Denmark), Tyndall Institute (Ireland), Össur (Iceland) and SciTech Link HB (Sweden).

Silent headset lets users quietly commune with computers

By
Advances in voice recognition technology have seen it become a more viable form of computer interface, but it's not necessarily a quieter one. To prevent the click-clacking of keyboards being replaced by noisy man-machine conversations, MIT researchers are developing a new system called AlterEgo that allows people to talk to computers without speaking and listen to them without using their ears. At first glance, the AlterEgo headpiece looks like the product of a design student who didn't pay attention in class. Instead of the familiar combination of an earpiece and microphone, the device is a cumbersome white plastic curve like the jawbone of some strange animal that hangs off the wearer's ear and arcs over to touch the chin. It might look strange, but it's based on some fairly sophisticated technology. Inside the Alterego are electrodes that scan the jaw and face from neuromuscular signals produced when the wearer thinks about verbalizing words without...

Water purification: Running fuel cells on bacteria to purify water

By
Researchers in Norway have succeeded in getting bacteria to power a fuel cell. The "fuel" used is wastewater, and the products of the process are purified water droplets and electricity. This is an environmentally-friendly process for the purification of water derived from industrial processes and suchlike. It also generates small amounts of electricity -- in practice enough to drive a small fan, a sensor or a light-emitting diode. In the future, the researchers hope to scale up this energy generation to enable the same energy to be used to power the water purification process , which commonly consists of many stages, often involving mechanical and energy-demanding decontamination steps at its outset. Nature's own generator The biological fuel cell is powered by entirely natural processes -- with the help of living microorganisms. "In simple terms, this type of fuel cell works because the bacteria consume the waste materials found in the water," explains SINTEF...

Harry Potter and the Cursed Child

By
Small Intro About Harry Potter and the Cursed Child Based on an original new story by J.K. Rowling, Jack Thorne and John Tiffany, Harry Potter and the Cursed Child is a new play by Jack Thorne. It is the eighth story in the Harry Potter series and the first official Harry Potter story to be presented on stage. It was always difficult being Harry Potter and it isn’t much easier now that he is an overworked employee of the Ministry of Magic, a husband and father of three school-age children. While Harry grapples with the past that refuses to stay where it belongs, his youngest son Albus must struggle with the weight of a family legacy he never wanted. As past and present fuse ominously, both father and son learn the uncomfortable truth: sometimes, darkness comes from unexpected places. Harry Potter and the Cursed Child is one play presented in two Parts, which are intended to be seen in order on the same day (matinee and evening) or on two consecutive evenings. ...
