Abstract
A system for performing fluid level measurements on a biological subject, the system including at least one substrate including a plurality of microstructures configured to breach a stratum corneum of the subject, at least some microstructures including an electrode, a signal generator operatively connected to at least one microstructure to apply an electrical stimulatory signal to the at least one microstructure and at least one sensor operatively connected to at least one microstructure, the at least one sensor being configured to measure electrical response signals from at least one microstructure. The system also includes one or more electronic processing devices that determine measured response signals, the response signals being at least partially indicative of a bioimpedance and perform an analysis at least in part using the measured response signals to determine at least one indicator at least partially indicative of fluid levels in the subject.
