Diabetes, which affects almost 30 million Americans is the leading cause of kidney failure, lower-limb amputations, and adult-onset blindness. More than 20% of health care spending is for people with diagnosed diabetes. Diabetes technology is a term created in 1999 referring to the interface between the biological sciences and the physical sciences. The term describes engineered technologies applied primarily to monitor and treat diabetes. Currently eight of the most productive engineered technologies that are being applied to diabetes include: 1) blood glucose monitoring; 2) subcutaneous continuous glucose monitoring; 3) wearable and implantable sensors; 4) insulin pumps; 5) closed loop systems (artificial pancreas); 6) telemedicine / mobile health; 7) big data and precision medicine; and 8) cybersecurity of connected devices. This presentation will summarize current advances in these eight technologies and present a major unmet need for each of them. Barriers to achieving maximal benefits from all these technologies can be overcome by creative engineers, to meet the needs of patients with diabetes.
