Abstract
New wearable systems for noninvasive glucose sensing include an ultrasound generator, an ultrasound detector and a feedback unit. Methods for noninvasive glucose sensing using a wearable device include measuring a thickness (geometrical and/or optical) of a target tissue or a time of flight of ultrasound or optical pulses in the target tissue and determining a glucose value from the thickness of the target tissue or the time of flight in the target tissue in accordance with a target tissue thickness (geometrical and/or optical) or time of flight versus glucose calibration curve.
