Abstract

A U-shaped fiber optic sensor for measuring refractive index is applied to the monitoring of human skin condition. Since the fiber has its cladding removed at the U-shaped sensing tip, the output includes some information about the condition of the skin to which the sensor is applied. In this paper, the relation between the sensor output and the electric resistance of the skin is investigated. Besides this subject, the applicability of the sensor is investigated for humidity measurement utilizing water evaporation time or dew-point temperature.
