Abstract

A linear measurement of the water content of the s tratum corneum is presented, using a microwave probe operating at 1 GHz. The probe consists of a simple razor cut across a shorted microstrip termination. The fringing fields generated across the resulting open circuit decay exponentailly beyond the probe. When the skin is pressed against the probe, only the outermost layer of the stratum corneum is placed in the fields. Variations in the water content of this outer layer affect its dielectric constant and consequently its interaction with the microwave circuit. The water content of the stratum corneum of the finger, hand, and oot are presented. A calibration curve is also included.
