Skin hydration measurement system

Abstract

A hydration level tracking system and method measures microwave energy accepted by skin in a desired target area of a user or patient in order to determine, in real time and in vivo, representative hydration levels. A measurement unit comprises a transmitter operatively connected to an antenna to deliver energy towards appropriate layer. The measurement unit determines an accepted energy power value of the skin associated with the desired target area. This measurement energy power value is compared with a calibration value, and the difference is used to determine a representative hydration level value. The determined hydration value may further be acclimatized using additional sensed values compensating for biological and ambient factors relevant to the patient. The final determined hydration level value can be displayed for reading and/or transmitted and stored for recording for further reference.
