Scientists from Singapore have created batteries for smart contact lenses that are powered by tears as in the film "Mission Impossible"

Researchers at the renowned Nanyang Technological University in Singapore have developed ultra-thin batteries for smart contact lenses that are powered by tears.

Here's What We Know

The smart contact lenses featured in the film Mission Impossible have become a reality thanks to a new invention. Li Sok Wu, a scientist at Nanyang Technological University, told CNBC that a scene from the film Mission Impossible made him think about smart contact lenses.

The batteries, which are only 0.2 mm thick, can be charged by a tear, providing enough energy to power an augmented reality device. This technology could also be used to monitor sugar levels in diabetics.

The battery can be charged using a wired or chemical method. The latter method involves a chemical reaction between the glucose that covers the battery and sodium and chloride ions in a saline solution.

After eight hours of charging, the lens wearer will receive 80% of the capacity for the smart lenses, which is enough for several hours of use.

Although it is not yet known when these smart contact lenses will be available on the market, researchers are actively working to improve the technology.

They are expected to become available for a reasonable price.
