Requirements (Subjects that are assumed to be known)
Introduction to bioengineering Electronic technology in biomedicine Measuring instrumentation
The student that successfully finishes this course should understand the biomedical application, specify the user and technical specifications, and provide a complete protocol for the design of a medical instrument. Besides, after the completion of this course the student should be able to implement a functioning medical instrument using state-of-the-art electronics and sensor technologies. Special attention will be paid to safety and regulatory aspects applied to biomedical instrumentation.

Learning activities and methodology
Teaching methodology will be mainly based on lectures, seminars and practical sessions. Lectures will be used by the teachers to present the main concepts of the course. Seminars will be mainly dedicated to interactive discussion with the students and to stress and clarify the most interessing and difficult points. Deliverable exercises and presentations will be done during the sessions. Grading will be based on continuous evaluation (including a partial exam, practical sessions, and student participation in class and Aula Global) and a final exam covering the whole subject. Help sessions and tutorial classes will be held prior to the final exam. Attendance to lectures, short-exams or submission of possible homework is not compulsory. However, failure to attend any exam or submit the exercises before the deadline will result in a mark of 0 in the corresponding continuous evaluation block. The practical sessions will consist on laboratory work and visits to research or clinical centers. A laboratory report will be required for each of them. The attendance to practical sessions is mandatory. Failure to hand in the laboratory reports on time or unjustified lack of attendance will result in 0 marking for that continuous evaluation block.
Assessment System
