SENSORS AND ACTUATORS
The general objective of the course is to acquire an understanding of the modern sensors/microsensors and actuators. Learning outcomes (according to the Dublin descriptors):
#1 Knowledge and understanding: The course is aimed to acquire the methodologies for knowledge, understanding and analysis of sensors and actuators devices.
#2 Applying knowledge and understanding: Those skills will be stimulated and improved though both theoretical and applicative lectures.
#3 Making judgements: The course should provide the capability to understand and to analyse sensing and actuating devices.
#4 Communication skills: Students will improve technical language by classroom and laboratory theoretical lessons.
#5 Learning skills: Analysis of complex problems will let the student improving its comprehension skills by describing each complex problem using a scientific methodology.
