Even the simplest touch to skin sets off neural messaging so complex that scientists are only beginning to mimic it through engineering. At the Johns Hopkins Applied Physics Laboratory, researchers are exploring an approach that uses what’s known as e-dermis: pressure-reactive layered material. When attached to prosthetic hands, like the one holding this e-dermis patch, the material helps turn contact with another surface into a sensation the brain interprets as touch.
