ABSTRACT

People with diabetes face a life‑long optimization problem: to maintain strict glycemic control without increasing their risk for hypoglycemia. Since the discovery of insulin in 1921, the external regulation of diabetes became an interdisciplinary endeavor, which included a significant bioengineering component. Over the past 50 years the diabetes technology field progressed remarkably through continuous subcutaneous insulin infusion, mathematical models and computer simulation of the glucose system, real-time continuous glucose sensors, and control algorithms driving closed-loop control systems known as the “artificial pancreas” (AP). I will discuss how these bioengineering developments have accelerated AP research and will focus in particular on three key ingredients: the first computer simulator accepted by FDA as a substitute to animal trials in the design of diabetes optimization strategies, the smart glucose sensor concept, and the model predictive control strategies. Following a number of in-clinic trials, the quest for wearable ambulatory AP systems is now under way, with prototypes tested in outpatient and home studies during the past four years. Outpatient results are exciting and show that AP – still not a cure – is arguably the most promising bioengineering treatment of diabetes to date.
