Scientists in Singapore have found a way to develop a battery that could possibly break new ground on the road to smart contact lenses.
In recent years, electronically augmented contact lenses were developed to monitor glaucoma, deliver eye medication or project augmented-reality imagery onto the vision of the wearer.
“The most common battery 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 Dr. Yun Jeonghun, co-author of a paper on the. “Meanwhile, another mode of powering lenses, induction charging, requires a [metal] coil to be in the lens to transmit power, much like a wireless charging pad for a smartphone.”
