Scientists Innovate Ultra-Thin, Tear-Charged Battery for Smart Contact Lenses

Inspired by 'Mission Impossible,' the new battery aims to make smart contact lenses a practical reality with unique charging methods.

The battery measures only 0.2mm, fitting comfortably within standard contact lens thickness.
It can be charged using a biocompatible saline solution or even the wearer's tears.
Current battery output is low, but research is ongoing to enhance its capacity and voltage.
Potential applications include glucose monitoring for diabetic patients.
Cost-effective production is a priority for future commercialization.
