Study the application of accelerometers in a Pacemaker.

Design of a measurement system using optical transducers to measure concentration

Seminar 1 Students present a selected scientific article, and critically analyse the work.

Seminar 2 Students present a selected transducer and describes its advantages and disadvantages.

Final seminar: To summarize the course, examination and course evaluation

The aim of the course is to:

• develop deeper understanding about the common medical transducers
• present different methods for measuring temperature, pressure, force, flow and other important parameters in determining the circulation-, breathing- and excretory functions.
• study how different measurement techniques are used to determine the vital parameters of diagnostic importance.
• provide an engineering approach to develop a physiological measurement system

General admissions requirements incl documented proficiency in English and academic studies of 7,5 credits (previously 5 credits/points) within Electrical Engineering, Physics, Medical Technology or eqv.

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

If the course is discontinued, students may request to be examined during the following two academic years.

Obligatory activities: Labs (2 p), Seminar and project presentation.
