Researchers, led by Lee Seok Woo, a scientist and associate professor at Nanyang Technological University’s School of Electrical and electronic Engineering in Singapore, have developed a smart contact lens with an embedded ultra-thin battery that can be powered by your tears.

That’s right, it can be powered by a “biocompatible saline solution,” instead of a traditional lithium-ion cell found in smartphones and smartwatches. This battery can still be recharged using wires, but a glucose coating around the lens reacts when submerged in a saline solution, producing a charge. The innovation doesn’t stop there, as the smart contact lens can also be charged while still in your eye, due to our tears containing glucose. In other words, the more tears produced, the more your smart contact lens battery will be recharged.
