Scientists of Newcastle University and other UK-based universities are developing a new prosthetic hand, which will have a number of revolutionary features. For example, such as a natural sense of feedback and a realistic sense of touch. At the moment, even the most modern prostheses are not giving the user full freedom of hand movement. If a user does not look at his prosthetic hand, then he does not know its exact position and even the fingers are clenched or not. Therefore, the use of an artificial hand is uncomfortable and unnatural, and prosthesis movement is slow and clumsy.


Sensitive prosthetic hand can transmit information to the brain

Scientists are working now to develop prosthetic hand with some advanced possibilities. Dr. Kianoush Nazarpour, lecturer of Biomedical Engineering at the School of Electrical and Electronic Engineering at Newcastle University, said, that amputee will be able to feel the prosthesis as a real hand. Therefore, this innovative prosthesis will help user to feel an object, even with their eyes closed. Today, Nazarpour’s team is developing a system that accurately record pressure and temperature of the object in prosthetic hand, and retransmit the signals to the human brain. Scientists are developing a mechanism of correct translating the “electronics language” into a language of the brain. Thus, the user can to be completely immersed into the activities of his artificial limb.

A completely functional prototype could take another five to seven years to come to realization.
