That's how the Glucotrack claims to work. From their site:
GlucoTrack uses ultrasonic, electromagnetic and thermal technologies to non-invasively measure glucose levels in the blood. GlucoTrack is intended for use by Type 2 and pre-diabetics.
GlucoTrack combines the following technologies:
Ultrasound (speed of sound change within the tissue);
Electromagnetic (conductivity of the tissue);
Thermal (heat capacity of the tissue).
It's not approved by the FDA, but it appears to be selling in Australia, New Zealand, Spain, China, Korea, Italy and some others.
