I emailed decn and asked them that very question when I first saw a TV ad for continuous glucose monitoring patches several months ago. They replied no, they were not working on a patch, nor were they planning to. They said decn is too small of a company, the investment and time required were well beyond their resources and abilities. They also said they believed it will take years, if not decades, to perfect the technology, which seemed a little strange as I was watching an ad for a product that is already on the market.
