DEVICE FOR NON-INVASIVELY MEASURING GLUCOSE
First Claim
1. A unitary device for non-invasively measuring glucose level in a subject comprising:
- (a) ultrasonic piezo elements positioned on opposing portions of said device and surrounding a part of the subject'"'"'s body to which said device is attachable;
(b) capacitor plates positioned on opposing portions of said device and surrounding said part of the subject'"'"'s body to which said external means is attachable, and auto-oscillating means connected to said capacitor plates; and
(c) a heater and a sensor positioned in close juxtaposition to said part of the subject'"'"'s body to which said device is attachable.

Abstract
In order to increase the accuracy of non-invasive glucose measurement, the device uses a combination of three non-invasive methods: ultrasonic, electromagnetic and thermal. The non-invasive glucose monitor comprises a Main Unit, which drives three different sensor channels (one per technology), located on an external unit configured as an ear clip attached to the subject'"'"'s ear lobe. To effect the ultrasonic channel, ultrasonic piezo elements are positioned on opposing portions of the ear clip and thus opposite sides of the ear lobe. For implementation of the electromagnetic channel, capacitor plates are positioned on opposing portions of the ear clip and the ear lobe serves as the dielectric. The thermal channel includes a heater and a sensor positioned on the ear clip in close juxtaposition to the ear lobe.
