Transepidermal water loss sensor based on fast dew point hygrometer

A new idea of moisture content in human skin measurement with use of fast dew point hygrometer sensor is presented in the report. The hygrometer construction based on integration in the single semiconductor sensor structure with the impedance detector, the thermoresistor and the heater is described in the paper. Both the experimental results of the dew point hygrometer tests as well as initial empirical results from the measurements of TransEpidermal Water Loss (TEWL) are shown.
