In this framework, the CNR-INO role is dedicated to develop gas sensor technologies based on different transduction mechanism: optical and electrical.
The optical technology is based on the photoacoustic technique, in which the pressure variations induced in the gas from the absorption of the excitation-laser are detected through the oscillation of a thin silicon sheet (cantilever). The cantilever oscillation is further measured by means of an optical interferometer. This technology allows selective and real-time detection of harmful trace gases in air, such as for example CO2.
Chemiresistors (semiconductor sensors that use their own electrical resistance during exposure to a gaseous species) were instead used to track the patient’s health status by analyzing the odor of organic liquids. These sensors are not selective and are particularly effective in applications where the target is not a single molecule but a complex set of molecules (odor). Different odors are discriminated in an array of different chemiresistors, whose collective response is handled by a pattern recognition software.
