Determination of biological conditions using impedance measurements
First Claim
1. A method for the non-invasive determination of the concentration of a substance (glucose) in blood of a subject, the method comprising the steps of:
- (a) placing an electrical conducting probe against a skin surface of the subject, wherein the probe comprises a plurality of electrodes, each electrode comprising a spike, the spikes being laterally spaced apart from each other and being of sufficient length to penetrate the stratum corneum;
(b) passing an electrical current through the electrodes to obtain a value of impedance for the skin; and
(c) converting the impedance to said concentration.

Abstract
Apparatus and methods for the diagnostics of biological conditions using impedance measurements are provided wherein an electrical conducting probe can be placed against a skin surface of the subject, wherein the probe is made up of a plurality of electrodes in the form of spikes, the spikes being laterally spaced apart from each other and being of sufficient length to penetrate the stratum corneum, passing an electrical current through the electrodes to obtain a value of impedance for the skin, and converting the impedance to a concentration of a substance such as glucose in blood of a subject.
