Modeling and simulation of a polymer optical fiber humidity sensor for the skin microenvironment

Abstract

A polymer optical fiber (POF) humidity sensor to monitor the humidity of a skin microenvironment of wounds without removing the wound dressing is modelled by ray tracing based on Monte Carlo simulation. To produce the sensor, a sensitive zone is made by removing the cladding from a segment of POF and mesoporous SiO2 nanoparticles are deposited layer-bylayer. In this paper, there is a report that applied the ray tracing model to simulate POF humidity sensor characteristics and compared the experimental results that have been reported earlier. This sensor which is based on plastic optical fiber
