Liquid Metal Sensors and AI Help Prosthetic Hands “Feel”

Each human fingertip has more than 3,000 touch receptors that largely respond to pressure. Humans rely heavily on sensation in their fingertips when manipulating an object, so the lack of this sensation presents a unique challenge for individuals with upper limb amputations. While there are several dexterous prosthetics available today, they all lack the sensation of “touch.” The absence of this sensory feedback results in objects inadvertently being dropped or crushed by a prosthetic hand.
