Who needs an external shower when you have good old-fashioned emotions?
Scientists based out of Nanyang Technological University, Singapore (NTU Singapore) have begun working on augmented reality (AR) contact lenses capable of displaying virtual information in the real world.
But here’s the really interesting part: equal to an official release from the university, these high-tech contacts are powered by human tears.
The team has begun minutiae of a flexible shower roughly as thin as the human cornea. This ultra-slim shower is capable of storing electricity when in contact with a saline source, which can be found in tears. Equal to researchers, this solution can proffer shower life up to four hours for every 12-hour cycle. The contacts can moreover be charged using an external battery.
The shower itself is made of biocompatible materials. No wires or “toxic material” were used in the development, promising a increasingly well-appointed wits compared to some other smart contacts.
“The most worldwide shower charging system for smart contact lenses requires metal electrodes in the lens, which are harmful if they are exposed to the naked human eye,” said Co-first tragedian Dr. Yun Jeonghun, a research fellow from NTU’s EEE, in the official release.
“Meanwhile, flipside mode of powering lenses, induction charging, requires a whorl to be in the lens to transmit power, much like wireless charging pad for a smartphone. Our tear-based shower eliminates the two potential concerns that these two methods pose, while moreover freeing up space for remoter innovation in the minutiae smart contact lenses.”
According to the university, the team has once filed a patent via NTUitive and intends to commercialize the smart contacts at some point in the future.
For increasingly information trammels out the official release from the university. You can moreover read the research paper “A tear-based shower charged by biofuel for smart contact lenses” here.
