Scientists at Nanyang Technological University in Singapore are developing an augmented reality (AR) contact lens that can display virtual information in the real world. The most interesting thing is that this high-tech contact lens is Powered by electricity generated from human tears.
The team has developed a flexible battery as thin as the human cornea, an ultra-thin battery capable of storing electricity when exposed to a saline solution, which is a type of tear. According to the researchers, this solution can extend the battery life of the contact lens by 4 hours for every 12 hours of wearing, which can also be charged by an external battery.
The battery itself is made from biocompatible materials and was developed without the use of any wires or “toxic substances,” making it more comfortable than some other smart contact lenses. “The most common charging system for smart contact lenses requires the addition of metal electrodes to the lens, which if exposed to naked people Right now, that does the damage. Another way to power the lens is inductive charging, which involves incorporating a coil into the lens to transmit power, much like a wireless charging pad for a smartphone. Our tear-based battery eliminates both Two potential problems that may arise from this approach also open up room for further innovation and development of smart contact lenses.”
According to the university, the team has filed for a patent through Nanyang Technological University Innovation Center (NTUitive) and intends to commercialize the smart contact lens sometime in the future.
