As one whose connection to the sciences is through an engineering education, I’ve read about the idea of artificial pancreases for years, but nobody seems to be actually making them. A gadget that you could shoot full of insulin once a week and then would watch blood sugar for you and release insulin in accordance, would be regarded as the next best thing to getting a new pancreas. Isn’t a major problem with this that the insulin will not “keep” in a reservoir at body temperatures? So that it has to remain an externally attached appliance?
