Sensors and transducers
(objectives)
The aim of the course is to describe the principles of operation of the main ultrasonic sensors and transducers. They will be provided to students the basic knowledge of the acousto-electronic, in order to give the tools for the analysis and simulation of transduction systems. Particular emphasis will be given to the capacitive micromachined transducers on silicon, which represent the state of the art of the microsensors integrated technology. They will be also examined the piezoelectric sensors and transducers, with particular attention to biomedical sensors that involve the use of ultrasound. The exercises include the design and the realization of a complete acoustic system for gestural detecting in the space (touchless interface for PC).
