An extremely thin battery that charges when submerged in a saline solution has been created by scientists at the Nanyang Technological University in Singapore. This flexible battery is made of biocompatible materials and is as thin as a human cornea. Scientists plan on using it to power smart contact lenses in the future. Smart contact lenses can be worn directly on the eye by users and are currently being used to keep track of users’ health, treat vision problems and manage diseases such as diabetes. Their future applications include augmented reality and recording whatever the user sees and hears and transferring it to cloud storage. The newly innovated batteries are a safe source of power for smart contact lenses as compared to traditional batteries that contain metal.
