Course Catalog 2011-2012
ASE-3036 Microsensors, 5 cr
Suitable for postgraduate studies
Will not be lectured year 2011-2012
Passed exercises, laboratory works, seminar presentation, report and examination.
Completion parts must belong to the same implementation
After having passed the study module the student will understand the physical operating principles of micro sensors. He/she can classify the micro sensors and present them in a consistent way as energy converters. He knows several manufacturing methods of micro sensors and processes. The student is able to give examples of different micro sensor structures and is able to understand and analyse measurement connections and amplifiers that have been used with them. The student can model and simulate the function of simple micro sensors. He understands the limitations of the modelling. The student can list different micro sensors and of their application areas. The student understands the terms which are related to the encapsulation of micro sensors.

Evaluation criteria for the course
The grade of the course is determined by examination. If the student knows the core material well, there is a possibility to pass the course with grade 3. The supplementing knowledge must be also known in order to reach a grade of 4 or 5. If in the core material there are minor shortcomings, the student will have an opportunity for the grade 1 or 2 depending on the amount of the shortcomings. Activity in exercises gives the opportunity for the additional points in the examination. If there are considerable shortcomings in the knowledge of the core material, the student will not pass the course.
Numerical evaluation scale (1-5) will be used on the course
