“It’s like you have a hand again,” says Joe Hamilton, as U-M researchers amplify faint, latent signals from arm nerves to enable real-time, finger-level control of a robotic hand.

A revolution in motorized prosthetics has potential to improve quality and motion for people living with limb loss.

U-M surgeons and engineers are enabling amputees to control prosthetics using their own biological motor signals. Could regaining a sense of touch be next?
