This invention describes a system for continuously monitoring medical data, specifically glucose levels. It uses a small sensor placed under the skin that wirelessly communicates with a thin, flexible electronic patch worn on the skin directly above it. The patch sticks to the skin and contains the necessary electronics to receive data from the implanted sensor, specifically built on an insulating foil substrate with a thickness between 10 and 250 microns.
Why it matters: Filed in 2019, this concept predates significant advancements in flexible electronics manufacturing and miniaturization. These developments have made the production of thin, self-adhering patches with specific substrate thicknesses more feasible and cost-effective, potentially improving reliability for long-term wear.
