Articulated Prosthesis

Short answer: Articulated prosthetic hands have multiple jointed fingers to mimic a natural hand. Many are myoelectric: electrodes on the skin pick up electrical signals from muscles in the residual limb, and motors turn them into grips, pinches or pointing.

Video transcript: Articulated Prosthesis: Myoelectric Hands Read Electrical Signals From the User's Muscles

Did you know? Articulated prosthetic hands are advanced devices designed to replicate the functionality and appearance of a natural hand. These prosthetics feature multiple movable joints and fingers, enabling precise and natural-looking movements. Many articulated prosthetic hands are myoelectric, meaning they use electrical signals from the user's muscles to control movements. Sensors detect these signals and translate them into actions like gripping, pinching, or pointing. NOW YOU KNOW!
