Abstract

A method for non-invasive blood glucose monitoring with a wearable device may include illuminating, with an electromagnetic source module of a wearable device, an area of skin of a user. The method may include measuring a scattered electromagnetic energy reflected from the area of skin with an electromagnetic receiver module of the wearable device. The method may include calculating, with a processor coupled to the electromagnetic receiver module, a blood glucose level in response to the measurement of the scattered electromagnetic energy reflected from the area of skin. The method may include communicating the blood glucose level to an information handling system. The electromagnetic source module may include a photodiode or a microwave module. The information handling system may include an application configured for a smart phone, tablet, or computer. The information handling system may include a memory configured for storing a historical record including multiple blood glucose levels.
