The course aims to introduce students to issues of design, implementation and use of electronic instrumentation for biomedical applications. It develops in two parts. The first introduces the student to the basic techniques for the measurement electronics and the principles and measures for the implementation, employees in the industry, both in electro medical instruments, and in other sectors. For this purpose covers the main transducers, its electrical networks of conditioning and interfacing between micro-controllers and data acquisition systems A / D. The second part aims to explain the principles of operation and design of biomedical instrumentation for wider distribution, particularly with regard to electronical instrument, as well as the specific problems posed interfacing with a living organism and the use in a particular environment such as that formed from a health facility
