    Learning Activities and Methodology:

    - Theory: lectures 1.5 ECTS.
    o Static and dynamic sensor characteristics and theoretical concepts for designing conditing circuits related to the sensor type and application
    o Examples on lectures of using theoretical concepts and practical use of commercial sensors, for
    being able to select a specific sensor technology depending on the requirements of
    the industrial applications (solving new problems as part of lifelong learning recognition)
    o Communication skills are enhanced through reading of materials and written reports in
    English and Spanish.
    - Practical exercises in lectures. 2 ECTS
    o Problems are developed for being able to understand commercial sensor datasheets and circuits; students solve them individually or in groups of 2-3 students
    o Practical examples on extracting information from calibration curves
    o Identification of sensor technologies by analyzing manufacturer data sheets and
    installed instrumentation systems
    o To extract conclusions, they must also analyze, and interpret data and the following
    methodology is used
    o teacher provides individual questionnaires related to lab sessions and theoretical
    concepts which are fill in by each student,
    o there is a discussion and general correction in class;
    o afterwards they form groups of 2-3 students and prepare a report to be used in the
    session lab,
    - Lab sessions. 2,5 ECTS
    - Students must design and execute lab experiments with teacher support, such as:
    o characterizing temperature and strain sensors,
    o strain instrumentation system evaluation
    o design on some conditing circuits for temperature and strain measurements
    - Being able to use lab instrumentation: oscilloscopes, power sources, voltmeters
    - Being able to put to work and instrumentation system from discrete components (sensors, IC amplifiers...) and evaluate their correct performance
    - To extract conclusions, they must also analyze, and interpret data, comparing their
    results with manufacturer data sheets; and the following methodology is used
    o every student group (made up of 2-3 students) prepare a report on expected results
    on lab sessions and theoretical concepts to be developed in the lab
    o after measuring on the lab, they must analyze and interpret measured data and
    prepare a final report
    - Students are required to use commercial software and provide solutions to real-world
    problems.
    - They develop collaborative work, capacity to apply theoretical concepts, and capacity to
    make an experiment in time, meeting desired needs.

    Assessment System:

    The evaluation allows knowing the degree of satisfaction of the knowledge goal, thus all
    work of the students will be evaluated by using continuous evaluation of their activities
    by using exercises, exams, lab projects, and other activities.
    The following scoring will be used:
    a) Exercises, reports and related short exam: 8%.
    * 1 report by each system or circuit to be developed at the lab sessions (2 reports)
    * Evaluation of the report. Each questionnaire is evaluated separately, including solution
    adopted, and design. The evaluation should be discussed in public at practical lectures.
    * At least there will be an individual exam related to the concepts of the report in classroom.
    Afterwards they should elaborate a new memory with corrected results before the lab
    session in groups of 2-3 students.
    b) Short exams or test on-line or in the classroom: 12%.

    *To assess theory concepts, problem solving abilities and knowledge of contemporary
    issues affected by unknown commercial sensors.
    c) Academic activities with the teacher. Lab experiments: 20%.
    * Activities must be delivered on time. A theoretical report with expected results must be
    carried to the lab session
    * Evaluation of tools usage and circuits and link performance
    * Evaluation of the collaborative work of the members distinguishing roles.
    A final report with data and measurements interpretation should be delivered by the
    group.
    * Evaluation of the final report (or lab project memory). Project memory organization and
    written correctness should be evaluated.
    Responsibility of the result is shared by all members.
    As an alternative to the continuous evaluation, a final exam with a total value of 60% of
    10 will be made to the students not following continuous evaluation.
    d) Final exam with questions and problems: 60%. At least a score of 3.5 out of 10 should be obtained.
    * To assess theory concepts, problem solving abilities and knowledge of contemporary
    issues affected by novel technologies.
