SVILUPPO DI NUOVE TECNOLOGIE E-SENSING PER APPLICAZIONI IN AMBITO OSPEDALIERO

In the past decade, the techniques of "electronic sensing" technology or "e-sensing" have undergone major developments in terms of technical and commercial. The "e-sensing" is the ability to reproduce senses and recognition systems of the human by sensors. Research hasdeveloped technological equipment, also called electronic noses "e-nose" that can detect and recognize substances present in a gaseous mixture complex . An electronic nose is made from three different components: the first is the detection system of the gas, the system of processing the signals coming from the sensors and the system identification / recognition of the substances constituting the mixture. The aim of this work is to verify the efficiency of an "e-nose" recently developed in our laboratory. The "e-sensing" technology includes commercial sensors of low cost and has been designed for easy use even by non-expert and therefore able to reduce management costs. The device produced was then tested for biomedical applications, and specifically for the monitoring of specific biomarkers in the exhaled volatile human associated with certain diseases (eg. NH3 for diseases nefrologiche). This allows to achieve effective early diagnosis of the disease by reducing the time of treatment and, at the same time, reducing the invasiveness of diagnostic treatments.
