Sensors in Medicine
- The condition for enrollment in a given course is that the student has successfully completed or at least obtained a credit and has not exhausted all exam dates of the course:
- Electronic Circuits (F7PBBEO)
- Department of Biomedical Technology
This subject provides information about basic electronic devices - sensors, describes their operation principle, basic circuit configuration and application. The stress is aid mainly on clarifying of basic principles and practical utilization. Integral part of this course is basic information about sensors of non-electric quantities and their read-out circuits eg. strain related sensors (force, pressure, torque, vibration, displacement, acceleration etc.) magnetic field sensors, temperature sensors, chemical sensors, optical sensors and biosensors. The stress is aid on miniaturization, integration
Credit conditions: To obtain the credit, one absence is allowed, other absences are excused only by confirmation from the doctor and the student must replace the measurement. The student must be properly prepared for the exercise, which includes written preparation, including tables in the work diary. The output of each measurement is the processed values, which must be commented and discussed. These results must be presented to the teacher at the end of the lesson. The student is obliged to submit one excellent elaborated protocol according to the new model.
Requirements for the exam: The exam will take the form of a test, from the material that was discussed in lectures and seminars. The test will be written and will include questions with offered answers, of which only one is always correct.
Entry requirements of the course:
Successful completion of the course Theoretical Electrical Engineering
Output knowledge, skills, abilities and competences:
Students will get acquainted with the basic functions, principles of operation, construction, signal evaluation, replacement models, materials of basic types of sensors so that they are ready for their application in medical devices.
