Scientists and researchers from Nanyang Technical University, Singapore (NTU Singapore) have embarked on a mission to create a pair of smart contacts powered by human tears. The prototypical augmented reality (AR) contact lenses will offer real-time, heads-up display (HUD) information to users.
Powered with the tears of their wearers, the devices will incorporate slim, flexible battery technologies “as thin as a human cornea,” according to research.
Saline sources will power the device and generate electricity for storage in the flexible battery system, the university research paper ‘A tear-based battery charged by biofuel for smart contact lenses’ explained. Along with external chargers, the saline-powered charging system will allow users to extend the battery life for around four hours each 12-hour cycle.
South Korea’s Flexible Battery Technology
The developments come as South Korea aims to conquer the flexible battery market with novel research and development (R&D) pursuits.
For example, South Korean startup LiBEST teamed up with robotics firm Mand.ro, leading to a flexible battery system. The joint venture debuted an Exo-Sensor and Exo-Skeleton Gloves for haptic-based control systems. Using the new battery system, LiBEST could create prosthetic arms with ultra-small motors and gears to control the device. International researchers also helped to improve the battery’s durability for metaverse device use.
