Singapore scientists developed a flexible battery as thin as a human cornea which stores electricity when immersed in saline solution and could one day power smart contact lenses (CLs).
The battery’s development was led by Associate Professor Lee Seok Woo from the School of Electrical and Electronic Engineering at Nanyang Technological University (NTU).
Smart CLs can display visible information on the wearer’s corneas to access augmented reality, scientists explained. Current uses include vision correction, monitoring the wearer's health and flagging and treating people with chronic health conditions such as diabetes and glaucoma. In the future, smart CLs could be developed to record and transmit everything a wearer sees and hears to cloud-based data storage.
