Thanks to CTOnews.com netizen Xiao Xing _ 14 for the clue delivery! CTOnews.com, August 28 (Xinhua) scientists at Nanyang University of Technology in Singapore are developing augmented reality (AR) contact lenses that can display virtual information in the real world. Most interestingly, these high-tech contact lenses are powered by human tears.

The team has developed a flexible battery as thin as the human cornea. This ultra-thin battery can store electricity when exposed to a saline solution, and tears are a saline solution. CTOnews.com noted that the solution can extend the battery life of contact lenses by four hours for every 12 hours worn, and the contact lenses can also be recharged by an external battery.

The battery itself is made of biocompatible materials and does not use any wires or "toxic substances" during development, so it is 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 lenses, which can cause harm if exposed to naked people," Dr. Yin Zhengxun, a researcher and co-lead author of the School of Electrical and Electronic Engineering (EEE) at Nanyang technological University, said in an official press release. Another way to power the lens is inductive charging, which requires adding a coil to the lens to transmit power, just like the wireless charging board of a smartphone. Our tear-based battery eliminates two potential problems that may arise from these two methods, while making room for further innovation and development of smart contact lenses. "

According to the university, the team has applied for a patent through the Innovation Center of Nanyang technological University (NTUitive) and plans to commercialize smart contact lenses at some point in the future.
