Implanted sensor could give amputees better control of robotic hands

This study tests a new device called MIRA, which is implanted under the skin to pick up electrical signals from muscles in the arm. These signals are then used to control a robotic prosthetic hand. The trial involves 5 adults with a below-elbow amputation who will use the device for up to one year. The main goal is to check safety, but researchers will also see if the implant gives better control than standard skin electrodes.
