Temperature is one of the most important physical quantities. Temperature measurements are used in every field of life, especially electronics, electrical engineering, energy-related fields, including energy source and storage devices. The goal of this dissertation is to design and optimize the microsphere-based fiber-optic sensors construction for measurement of the sensor surrounding medium temperature, including selection of the optical microsphere optimal geometrical parameters and selection of the parameters of the ZnO (zinc oxide) coatings deposited by Atomic Layer Deposition (ALD) method. A comprehensive state of the art about the significance of temperature measurements and measurement methods was performed as well. In the dissertation, the fabrication and the characterization of the designed sensors are described. Experimental results of the measurements validating a proper operation of the sensors are presented. Applications of the microsphere-based fiber-optic sensors, firstly as a device for in situ monitoring of the temperature of the supercapacitors and secondly for investigation of the optical and thermal properties of the few-layer black phosphorus coating was proposed.
