A group of IMT Atlantique researchers has developed a way to integrate a flexible battery into a contact lens.
Electronic contact lenses have been in development for more than a decade in several laboratories around the world. And, having electronic.
Components integrated into a contact lens can provide a series of medical capabilities, such as measuring intraocular pressure, analyzing tears to determine glucose levels and helping people with visual impairments.
While the science of making smart contact lenses has progressed significantly in recent times, there is still a great challenge on how to power these devices so that they can make relevant procedures and also do so for long periods of time.
“This first initiative is part of a larger and more ambitious project that aims to create a new generation of oculometers linked to the appearance of augmented reality helmets that have given rise to new uses”
Aware of this situation, a group of researchers from IMT Atlantique, a French university of Engineering working with the LCS company, manufacturer of contact lenses based in Caen, has developed a way to integrate a flexible battery in a contact lens.
The micro-battery is capable of providing enough energy to light a light-emitting diode (LED) for a few hours, which will probably become the first time that there is so much energy available within a contact lens.
Previously, researchers generally relied on wireless power transmission, which is extremely limited in terms of the amount of useful energy it can offer.
This first initiative is part of a larger and more ambitious project that aims to create a new generation of oculometers linked to the appearance of augmented reality helmets that have given rise to new uses, such as human-machine interfaces or cognitive load analysis.
This opens up great markets, while at the same time imposing new restrictions on precision and integration, “said Professor Jean-Louis de Bougrenet de la Tocnaye, of IMT Atlantique.
