Electrochemical gas sensors are vital for health and safety, but commercial aqueous-based devices have limited lifetimes in extreme conditions; therefore, non-volatile ionic liquid electrolytes can be used as more robust alternatives. In this thesis, the influence of humidity and ionic liquid structure on the electrochemical responses of oxygen, ammonia and sulfur dioxide were studied. The results provide new knowledge on ionic liquid-based sensors for robust, low-cost and miniaturized gas sensing in real environments.
