A system for performing measurements on a biological subject, the system including: at least one substrate including a plurality of plate microstructures configured to breach a stratum corneum of the subject; at least one sensor operatively connected to at least one microstructure, the at least one sensor being configured to measure response signals from the at least one microstructure; and, one or more electronic processing devices configured to: determine measured response signals; and, at least one of: provide an output based on measured response signals; perform an analysis at least in part using the measured response signals; and, store data at least partially indicative of the measured response signals.

Disclosed is a step counting method comprising the steps of, firstly, acquiring an electric signal on an electrode that is in contact or coupled with a human skin, the signal is caused by the human body capacitance variation during foot-lifting and foot-landing; secondly, processing the electric signal by a signal processing circuit that is electrically connected with the electrode and outputting a signal stream that records the foot-lifting and foot-landing information to a central control unit; and thirdly, analyzing the received signal stream by the central control unit that is electrically connected with the signal processing circuit to calculate the step number. The proposed step counting method accomplished by monitoring the electric signal on the electrode caused by the human body capacitance variation can improve the step counting accuracy.
