Switzerland develops a bionic "smart hand" that senses the texture of objects

Release date: 2014-03-27


Although the international market has long been a variety of prosthetic limbs, these prostheses cannot sense the weight and texture of objects like the upper limbs or lower limbs of normal humans. After the Massachusetts Institute of Technology, researchers at the University of Technology in Lausanne, Switzerland, recently developed a A new bionic smart hand that senses object weight, finish and various other sensory indicators. After years of research, Swiss scientists have measured the subtle changes in the bioelectric current produced by the tendon of a human hand after touching the object, converting it into data and storing it in a chip, and then mounting the chip on a bionic hand. When the person who lost the hand installed this novel smart hand, when he touched the object with this hand, the sensor sensed the shape and texture of the object and then transmitted it to the chip through the electrode and converted it into bio-current, finally through the arm. The nerve plexus is transmitted directly to the central nervous system of the brain and produces a sense that allows people to correctly perceive important information such as the weight and texture of the object. Once the biomimetic smart hand can be marketed through clinical trials and expert appraisals, it will bring good news to people around the world who have lost their hands due to work-related injuries, wars or car accidents.
