Scientists have developed an ultra-thin battery for smart contact lenses that can be charged with tears

Scientist Lee Seok Woo of the School of Electrical and Electronic Engineering at Nanyang Technological University said a scene from the movie «Mission Impossible» inspired his latest invention — batteries for smart contact lenses. In the fourth movie in the series, an agent wears contact lenses that can recognize faces and monitor eyes. Lee wanted to make this lens a reality.
