Researchers have developed the first magnet-controlled prosthetic hand, enabling amputees to perform precise everyday tasks.
The team mapped movements to control a robotic hand , using magnets and an algorithm that converts muscle contractions into specific commands.
The prosthetic hand operates without wires or electrical connections, relying solely on magnets and muscles to control finger movements. This allows users to perform everyday tasks like opening jars, using screwdrivers, and picking up coins. “There are 20 muscles in the forearm and many of them control the hand movements. Many people who have lost a hand keep on feeling it as if it is still in place and the residual muscles move in response to the commands from the brain,” said Cipriani.The study team mapped the movements to direct the robotic hand’s fingers and converted them into signals. The magnets have an inherent magnetic field that is easily localized in space.
“To make the connection between the residual arm where the magnets were implanted and the robotic hand easier, we made a carbon fibre prosthetic socket containing the electronic system capable of localising the movement of the magnets” said Cipriani.
