The Tampere University of Technology (TUT) in Finland has developed an artificial iris that can react to incoming light in exactly the same way as the human eye. Manufactured from an intelligent, light-controlled polymer (a liquid crystal elastomer) material, the iris expands when exposed to light and shrinks when the environment becomes darker. All modern camera lenses have light detection built-in, but unlike those, this iris requires no power source or external light detection system. Aside from its future potential with camera design, scientists are confident that eventually this technology will be able to be used as an optical implant. “An…
