An Optical Temperature Sensor in light of Silicone and Plastic Optical Fibers for Biomedical Applications

An ease and easy to acknowledge optical temperature sensor is proposed. The sensor is created on the fiber end by expelling, close to the fiber tip, the cladding of a multimode plastic optical fiber (POF) with a cleaning procedure, to store, by plunge covering, a silicone layer around the fiber tip. We have tentatively tried the sensor by measuring, at various wavelengths, the temperature of a water shower. The best sensor's exhibitions were acquired at a wavelength of 625 nm. The novel polymer optical fiber sensor shows a decent straight reaction in the temperature extend from 24°C to 46°C. This temperature extend is intriguing for hyperthermia in tumor treatment.
