Comparison of transepidermal water loss (TEWL) measurements with two novel sensors based on different sensing principles

In this paper we compare results of TEWL measurements carried out with two different instruments recently developed in our institutes. One sensor is based on a dew point hygrometer, while the other one uses a conductance type humidity sensor. In both cases the closed chamber measuring method is used...

Description
Summary:In this paper we compare results of TEWL measurements carried out with two different instruments recently developed in our institutes. One sensor is based on a dew point hygrometer, while the other one uses a conductance type humidity sensor. In both cases the closed chamber measuring method is used. Furthermore, we have applied the same principle of calibration to both instruments.
