‘Electronic skin’ allows user to experience a sense of touch and pain; ‘After many years, I felt my hand, as if a hollow shell got filled with life again,’ amputee volunteer says
Amputees often experience the sensation of a “phantom limb”—a feeling that a missing body part is still there.
That sensory illusion is closer to becoming a reality thanks to a team of engineers at Johns Hopkins University that has created an electronic skin. When layered on top of prosthetic hands, this e-dermis brings back a real sense of touch through the fingertips.
“After many years, I felt my hand, as if a hollow shell got filled with life again,” says the amputee who served as the team’s principal volunteer. (The research protocol used in the study does not allow identification of the amputee volunteers.)
Made of fabric and rubber laced with sensors to mimic nerve endings, e-dermis recreates a sense of touch as well as pain by sensing stimuli and relaying the impulses back to the peripheral nerves.
“We’ve made a sensor that goes over the fingertips of a prosthetic hand and acts like your own skin would,” says Luke Osborn, a graduate student in biomedical engineering. “It’s inspired by what is happening in human biology, with receptors for both touch and pain.
