FLUID STATUS MONITORING

A system for monitoring a fluid status of a biological subject, the system including at least one substrate including a plurality of microstructures including electrodes configured to breach a stratum corneum of the subject, a signal generator configured to apply an electrical stimulatory signal between electrodes on different microstructures, at least one signal sensor configured to measure electrical response signals between electrodes on different microstructures and one or more electronic processing devices that are configured to determine changes in bioimpedance using the measured electrical response signals and analyse the changes in bioimpedance to determine at least one indicator at least partially indicative of the fluid status of the subject.
