This coin-sized smart insulin patch could monitor glucose for diabetes managementA team of researchers and bioengineers from UCLA, the University of North Carolina School of Medicine and the Massachusetts Institute of Technology announced in February that they had developed a smart insulin-delivery patch with the potential to also monitor and manage glucose levels in people with diabetes.
The adhesive patch monitors blood sugar and has doses of insulin pre-loaded in tiny microneedles on the patch to deliver medicine quickly when glucose levels reach a certain level. The insulin delivery slows down once it detects glucose levels are back in a normal range. It is the size of a quarter and can be easily manufactured for once-a-day use.
