Description
Researchers from the Microelectronic Lab at the University of Glasgow, in collaboration with Wöhlk Contactlinsen GmbH and Aarhus University, have developed a new, safe, and non-invasive platform for monitoring brain activity and other vital signs – modified electronic contact lenses. These contact lenses are composed of a flexible polyimide material and have a small, donut-shaped antenna integrated into the design, which is used for power and data transfer. This technology is based on inductively coupling power transfer (ICPT) and operates at a frequency of 2.4-2.5 GHz, as approved by the FDA. The team also tested the heat generation during the power delivery process, which was found to be safe. This device could revolutionize the monitoring of vital signs without the need for invasive injections and could even be used for more than just vision correction. These non invasive contact lenses provide a potential for wireless health monitoring. They can be especially useful for monitoring progression of Alzheimer’s, Parkinson’s and Diabetes. They may also provide a protective measure against glaucoma.
