Learning outcomes
The course has the aim to provide to the student with fundamental knowledge of correct design and use of the measurement systems, with particular attention to the area of the biomedical instrumentation and measurement procedures for human health.
For the sector of the biomedical engineering, this course will provide the knowledge for the design and correct use the measurement devices for mechanical, thermal and flu dynamical fields, with specific attention to the biomedical instrumentation and human health sector. The course will have a frontal lessons and laboratory/seminars.
The student will develop the skill to analyze the fundamental measurement systems and main transducers The didactic activity will also include the laboratory sessions/seminars and the preparation of a project aiming to analyze and present a standard biomedical system.

Development of the examination
All of the students have to discuss an experimental project concerning one of the course subjects. This project can be developed individually or in groups of max. 3 students. The examination consists in an oral discussion and the presentation of the experimental project and in an oral discussion of the subjects discussed during the course.

Presentation of the final mark expressed in thirtieths, evaluating the answers on the basis of accuracy, completeness, deepening, exposure method and the experimental project according to diligence and deepening level.

The student, during the thesis discussion and the oral exam, has to prove to know the program arguments. To pass the exam successfully, the student has to demonstrate to have a global knowledge of the teaching contents, exposed correctly with the usage of suitable technical terminology, with the formal and graphic engineering instruments, that is schemes, block diagrams, analytical formulations, exc… With regard to the experimental project, the student has to prove to have accurately carried out the consigned task and to have a deep knowledge on that argument, on the laboratory instrumentation and to be able to use the multimedial presentation instrument, useful for the future career. The best mark will be obtained proving a deep knowledge of the teaching contents, exposed with perfect mastery of the technical language.

The exam consists of three questions and the discussion of the experimental project, the mark will be expressed in thirties. The final mark is the mean value of the marks of each question and it represents an overall rating of the exam. Full mark with honours will be granted to the students who will demonstrate a great mastery of the subjects.
