Artificial skin experiment: (a) experimental setup for the watch-type sweat rate sensor characterization; (b) time-dependent relative capacitance in the five different sweat rate conditions during three measurement cycles; (c) capacitance rising rate depending on the sweat rate ranging from 3.76 g/m2h to 137.68 g/m2h; (d) capacitance rising rate depending on the sweat rate, in the three different air velocity conditions in the ranges of 0~0.5 m/s, 0.5~1.0 m/s, and 1.0~1.5 m/s.
