Neuroprosthetics

Neuroprosthetics are special medical devices that can be used to replace lost or damaged body parts. They are connected to the brain and nerves, so they can help people move the body part they replaced. For example, a neuroprosthetic arm can help someone move their arm to pick things up or give a fist bump! Neuroprosthetics use tiny electrical signals that come from the brain to make things happen.
