Scientists develop smart tactile bionic prostheses to restore the touch of the disabled
Release date: 2014-10-10 According to foreign media reports, the new prosthesis can restore the touch of the disabled. Researchers have revealed that two patients have worn prostheses that are directly connected to their bones and nervous system. They can recognize that the skin touches the object, and can do everything from eucalyptus wood to driving. A patient who lost his right hand due to an industrial accident four years ago sensed the object again with the tactile function of the bionic hand. Igor Spetic, wearing a blindfold, was able to realize that the researchers used a cotton ball to gently brush the hair of their bionic back. He said that he could immediately feel that it was a cotton ball. A seven-mm "electrode wristband" wraps around the main nerves of the arm to transmit the tactile nerves through the contact stimulus. When the wristband is attached to Spetic's right arm nerve, he can sense the tactile information on the back and fingers of the artificial hand, from coarse sandpaper to smooth metal. The system is currently in the laboratory development phase, and Spetic has installed the prosthesis for two and a half years. The second patient has also used the prosthesis for 18 months. Similar tactile functions have been reported previously in bionic hands, but in some cases the tactile function will diminish in a few weeks. Since the two patients in the study are currently functioning properly, the researchers hope that the method will be promoted, and it is optimistic that the system will be implemented in five years. At present, Spetic can use bionic hands to do everything in daily life and work, and it is not affected by the environment.
