Liquid metal sensors and AI could help prosthetic hands to 'feel'


Each fingertip has more than 3,000 touch receptors, which largely respond to pressure. Humans rely heavily on sensation in their fingertips when manipulating an object. The lack of this sensation presents a unique challenge for individuals with upper limb amputations. While there are several high-tech, 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.
