IOS has been focusing on the development of optical chemical sensors and biosensors. Although uncommonly used, these kinds of sensors have certain advantages compared to other types of sensors, since they do not require a reference cell to set, can be miniaturized, do not interfere with the electric and magnetic fields, and can also be connected to optical fibres, which enable long distance transmission of signals. They have low energy consumption. Optical sensors allow their installation in the garment or can be part of personal equipment for personal protection and/or control.

By monitoring the physical, chemical and biochemical properties of a certain parameter, these sensors ensure better quality of life by enabling precise medical diagnoses, effective industrial processes, safe food and a clean environment. They also aid the overall socioeconomic development.

We develop a receptor part of the optical chemical sensor, which serves as an identification phase for sensing specific parameter (in water or air), as well as the transducer part, which both allow us the preparation of the final sensor system prototype. Our goal is to find solutions and to prepare sensor systems for real applications.
