Course Description

Gas Sensors


Sensor Technologies


prof. dr. Uroš Cvelbar


The objective of the course is to deliver to the students the existing knowledge of advanced gas sensors.

Students will be acquainted with modern gas sensors with special emphasis on catalytic and semi-conductor gas sensors. They will learn about the gas sensor use for detection of specific gaseous molecules, advanced signal acquisition and processing techniques, new technologies for their manufacturing, determination of selectivity and use of new materials for gas sensing.

Students will develop the ability to solve independent research and development tasks in the field of advanced gas sensors, including design, building, testing, and performance evaluation.


Identification of gas sensor application and detection of different gases. Basics of gas sensor operation in respect to different gas sensor type including catalytic, electrochemical, infrared and semi-conductor sensors.

New techniques in signal processing on catalytic and semi-conductor gas sensors: potentiometric, amperometric, resistive and resonant.

New methods and mathematical tools for signal processing from gas sensor and their analysis.

New technologies for building catalytic and semi-conductor gas sensors, design of electrodes and materials for their manufacturing.

Advanced systems for detection of gaseous molecules, multi-array sensor systems and determination of selectivity, use of nanomaterials and quantum dots.
