Course Information


The course “Engineering Aspects of Medical Technology” focuses on the engineering side of medical technology.

Motivated by the diagnostically relevant need to acquire patients’ data, the students will learn how important physiological quantities can be measured and how materials properties can be utilized to measure those. Comparison between pioneering work and modern devices are meant to emphasize the underlying physical detection principle and its improvements. By working through a standard for biomaterials testing, the students will gain an impression how to read standards for selected aspects of the special requirements for medical devices.

Topics of this course include:

  • The origin and relevance of physiological measurands
  • Sensing principles for movement, change of volume, flow, conductivity, absorption, force, pressure and more
  • Electronic properties of materials and the body, like resistance, capacitance, inductivity (impedance)
  • Detection schemes for non-linear response in the time domain
  • Optical absorption of oxygen saturated and depleted blood
  • Thermometry through bolometers and pyrometers
  • Examples for microfluidic devices and corresponding schemes for mixing and control of flow
  • Interface properties of medically relevant applications are covered by examples of skin mounted electrodes and biocompatibility aspects of implants

The course consists of a weekly 45 min lecture, which is meant to motivate for the detailed treatment of a certain effect or technique by putting it into an applied context. The weekly 90 min exercises are designed to learn the skills which are necessary to solve the previously outlined sub-problem.

Learning outcome Knowledge

After completion of this course origin, relevance and acquisition of physiological measurands can be explained. The participants will be familiar with the special requirements for medical devices.


The students will learn how physiological quantities can be transduced into an electrically measurable property. Methods for utilizing nonlinearities and time varying signals will be applied.


The participant will be able to apply amplification mechanisms, noise suppression and frequency domain analyses. Sensor types and detecting priciples can be compared with each other.
