Fabrication and evaluation of the sweat measurement system for palmar hyperhydrosis

Abstract

Sweating have a central function in body temperature control. But the abnormal secretion of sweat causes the sweat stain to document and the equipment break and decreases the incentive to work. Although there are various approach such as surgery and medication, these treatment method have problems such as side effect, invasiveness and the compensated sudation. We focus on the psychological therapy without side effect and invasiveness and set as an ultimate goal to fabricate the biofeedback treatment system. In this study, the humidity sensor was attached to a hand via self-produced jig and temporal change of humidity was measured. In the results, the humidity increase with time and the gradient of humidity change was different by subjects. This result suggests that the humidity would be available as a sweat indicator.
