Chameleon-inspired stretchable e-skin changes color when touched

(Phys.org)—Researchers at Stanford University have fabricated a stretchable, color-changing, pressure-sensitive material–basically the closest thing yet to an artificial chameleon skin. Touching the new electronic skin (e-skin) with varying amounts of pressure causes it to change colors, as the pressure indirectly alters the chemical structure, and subsequently the optical properties, of the "electrochromic" material. The e-skin could have applications in interactive wearable devices, artificial prosthetics, and smart robots.
