The EU-funded PHOTOTUNE project newly highlighted its potential for medical applications as well as the next generation of robotics. The science of photonics continues to impact including telecommunications and information processing. The PHOTOTUNE project’s experts published Advanced Materials journal study. The study declared the formation of an artificial iris which can react to light much as a human eye does. The recent study called the photo-alignment technology combines with the light-sensitive liquid crystal elastomers to create the iris. The ability to function more autonomously than previous efforts makes the invention stand out and it does not depend on external light detection systems. The Associate Professor and head of the research group said, “‘An autonomous iris that can independently adjust its shape and the size of its aperture in response to the amount of incoming light is a new innovation in the field of light deformable materials”.
The iris is nothing but the tissue in the eye which controls the amount of light that lease into the eye over adjustments of the eye’s pupil size while ensuring the retina receives the right amount of light. As Associate Professor Priimägi said, “The artificial iris looks a little bit like a contact lens and its center opens and closes according to the amount of light that hits it”. The process is attached by the camera technology whereas the cameras depend on the process that uses light detection systems to adjust the amount of incoming light. The modern technology is used to treat the iris defects but the experts stated that most of the work is lies ahead before it is ready to be rolled out. An Associate Professor Priimägi said, “Our next goal is to make the iris function also in aqueous environments”. Further, Professor Priimägi added, “Another important goal will be to increase the sensitivity of the device in order to make it react to smaller changes in the amount of incoming light. These developments will be the next steps towards possible biomedical applications”.
