Electronic Contact Lenses Can Now Integrate Micro-Battery to Power Them

Researchers at IMT Atlantique, a French engineering university, working with folks from LCS, a contact lens manufacturer based in Caen, have now developed a way to integrate a flexible battery into a contact lens. The micro-battery is able to provide enough power to illuminate a light-emitting diode (LED) for a few hours, which is probably the first time that so much power was available inside a contact lens. Previously, researchers generally relied on wireless energy transmission, which is extremely limited at how much useful power it can deliver.

“This first project is part of a larger and very ambitious project aimed at creating a new generation of oculometers linked to the emergence of augmented reality helmets that have given rise to new uses (man-machine interfaces, cognitive load analysis, etc.). This opens up huge markets, while at the same time imposing new constraints on precision and integration.” in a published statemens said IMT Atlantique professor Jean-Louis de Bougrenet de la Tocnaye

The researchers aren’t necessarily looking at medical uses for their technology, but that’s certainly on the menu as other engineers will be able to take advantage of this to power health-based contacts.
