Prosthetics currently lack the sensation of “touch.” To enable a more natural feeling prosthetic hand interface, researchers are the first to incorporate stretchable tactile sensors using liquid metal and machine learning. This hierarchical multi-finger tactile sensation integration could provide a higher level of intelligence for artificial hands by improving control, providing haptic feedback and reconnecting amputees to a previously severed sense of touch.

Load-reducing backpack powers electronics by harvesting energy from walking
Researchers have developed a prototype backpack that makes loads feel about 20% lighter and harvests energy from human movement to power small electronics.
