Bioengineered scaffold could restore sense of touch to prosthetic limbs

Existing robotic prostheses have limited motor control, provide no sensory feedback and can be uncomfortable to wear. In an effort to make a prosthesis that moves like a normal hand, researchers at the University of Michigan have bioengineered a scaffold that is placed over severed nerve endings like a sleeve and could improve the function of prosthetic hands and possibly restore the sense of touch for injured patients.
