Patent ID: 8235897

Claim:
A device for non-invasively measuring glucose level in a subject comprising: a unitary external unit having a first portion and an opposing second portion configured to receive a part of the subject's body therebetween; (a) a first ultrasonic piezo element positioned on the first portion and a second ultrasonic piezo element positioned on the opposing second portion of said external unit, a first membrane covering the first ultrasonic piezo element and a second membrane covering the second ultrasonic piezo element for measuring glucose levels utilizing ultrasonics; (b) the first membrane and the second membrane constituting respective first and second capacitor plates with an auto-oscillating means connected thereto for measuring glucose levels utilizing electromagnetics; and (c) a heater and a thermal sensor both positioned on the first portion and spaced from the first ultrasonic piezo element for measuring glucose level by thermal characteristics.
