Abstract
We present a polymer optical fibre sensor to sense skin moisture and droplet formation when sweating occurs. The sensor used evanescent field attenuation, by exploiting a moisture sensitive cladding with moisture indicator (fluorescein) contained within a porous cladding (HEMA). The sensor was designed to be comfortable to wear and unobtrusive, hygienic, with sterilised interchangeable sensing elements. It had maximum sensitivity between 98% and 100% humidity, and response time of 24 seconds.
