Strengthening of the Italian Research Infrastructure for Metrology and Open Access Data in support to the Agrifood
ENEA3 – Smart Spectoscopical Sensors and IoT
(Reference person: Luca Fiorani)
The OU Smart spectroscopical sensors and IoT applies spectroscopical techniques, in general, and laser photoacoustic spectroscopy (LPAS), in particular, to the quality control of the agri-food chain. Although a wide range of cutting-edge methods are in the armoury of the OU – LIBS (Laser induced breakdown spectroscopy), FTIR (Fourier-transform infrared spectrosocopy), Raman spectroscopy, Spectro fluorometry, Remote sensing – its flagship is laser photoacoustic spectroscopy (LPAS). In a typical LPAS system, a laser beam is modulated at an audio frequency and injected into a resonant cell where it hits the investigated sample that absorbs the incident radiation. Consequently, the part of the sample irradiated by the beam experiences a rise in temperature and volume, thus producing a pressure wave. In general, the sound detection subsystem is made of a microphone connected with a lock-in amplifier synchronized with the modulator. The output signal is proportional to the sample absorption and typical experiments are conducted in the “fingerprint region”. Main advantages are rapidity, sensitivity, specificity, simplicity, repeatability, in situ measurement, uncomplicated sampling, ease of use, and cost-effectiveness. Current systems are robust and small, allowing to develop portable systems in industrial settings a portable system.
The OU will make available its smart sensors and devices to the end-user community, along with a spectroscopical database and a virtual Lab.
