For a long time, researchers have been trying to work on giving a natural sense of muscles to prosthetic limbs. According to a research by Rice University, the University of Pisa and Italian Institute of Technology, haptic feedback could help in providing patients the ability to discern the size and feel objects without looking at them. "Humans have an innate sense of how the parts of their bodies are positioned, even if they can't see them. This'muscle sense' is what allows people to type on a keyboard, hold a cup, throw a ball, use a brake pedal and do countless other daily tasks," said Marcia O'Malley, professor of mechanical engineering at Rice said in the press release issued Tuesday.
