Abstract

The monitoring of target physical parameters in sterilizers includes temperature and air pressure monitoring. The aim of air pressure monitoring is to ensure that the dry and pure saturated water steam is working properly for sterilization. In our previous study，we have accomplished real-time， dynamic temperature monitoring of the whole process of sterilization using fiber Bragg gratings （FBG）. In this work，we aim to obtain an integrated monitoring system of physical parameters based on FBGs for sterilizers. The proposed method is based on a polyimide-coated FBG to monitor gas quality during sterilization. Firstly， we evaluate both temperature stability and sensitivity of the polyimide-coated FBG. Then， the response to water vapor density is examined during the exhaust and drying periods of the qualified sterilizer. Finally，a system is proposed for the monitoring of gas quality through a polyimide-coated FBG and for the monitoring of temperature by a FBG encapsulated in capillary stainless-steel tubes. The polyimide-coated FBG showed excellent temperature stability during sterilization with a sensitivity of 0.014 3 nm/°C. The response of the sensor to water vapor density can be represented by the piecewise lines，and their individual sensitivities were 8.994 2×10

）. The proposed sensing structure working within pre-vacuum and sterilizing periods can effectively evaluate the drying and pure characteristics of water steam during sterilization. This study provides a new method for the monitoring of physical parameters of the sterilizer，which has many advantages such as safety，convenience， low cost and no electromagnetic interferences.
