      Prosthetic Hand Restores Amputee's Sense of Touch

      Implanted electrodes make this haptic hand feel like the real deal

      Igor Spetic lost his right hand in an industrial accident. Then he started working with Dustin J. Tyler, a researcher in human-machine interaction, to help develop an experimental haptic prosthetic that lets Spetic feel sensations in his missing hand.

      To make the prosthetic work, Tyler tapped into Spetic’s nervous system. Implanted electrodes in the right forearm make contact with three nerves at 20 locations. Stimulating different nerve fibers produces realistic sensations: When one spot is stimulated, he feels a touch on his right palm; another spot produces sensation in his thumb. Thin-film force sensors in the device’s index and middle fingers and it’s thumb can trigger the corresponding nerve stimulation.

      Right now, the haptic system is rudimentary and can be used only in the lab, but the researchers hope that, eventually, they’ll be able to engineer a prosthesis that is just as capable as the hand that was lost.

      With 360-degree video, IEEE Spectrum puts you aboard drones that are flying high above the Tanzanian landscape: You’ll ride along as drones soar above farms, towns, and the blue expanse of Lake Victoria. You’ll also meet the local entrepreneurs who are creating a new industry, finding applications for their drones in land surveying and delivery. And you’ll get a close-up view from a bamboo grove as a drone pilot named Bornlove builds a flying machine from bamboo and other materials.

      You can follow the action in a 360-degree video in three ways: 1) Watch on your computer, using your mouse to click and drag on the video; 2) watch on your phone, moving the phone around to change your view; or 3) watch on a VR headset for the full immersive experience.

      With 360 video, IEEE Spectrum takes you behind the scenes with one of the world’s first drone-delivery companies. Zipline, based in California, is using drones to deliver blood to hospitals throughout Rwanda. At an operations center in Muhanga, you’ll watch as Zipline technicians assemble the modular drones, fill their cargo holds, and launch them via catapult. You’ll see a package float down from the sky above a rural hospital, and you’ll get a closeup look at Zipline’s ingenious method for capturing returning drones.

      You can follow the action in a 360-degree video in three ways: 1) Watch on your computer, using your mouse to click and drag on the video; 2) watch on your phone, moving the phone around to change your view; or 3) watch on a VR headset for the full immersive experience.

      Do your travel plans include New York City? Are you a techie? If the answer to those questions is yes, let IEEE Spectrum be your guide! We've put together a list of some of our favorite places to visit, including important locations in the history of electrotechnology (New York was once the center of the electrical and electronic world) and places where fun and interesting things are happening today. See where Nikola Tesla lived, check out cutting-edge artists working with technology, or take the kids to see an Atlas and Titan rocket.

      All the locations are accessible via the subway, and many are free to visit. If you do visit, take a selfie and post a link in the comments below.
