Master thesis: Development of a torque measurement device

Master thesis: Development of a torque measurement device for ensuring quality of Fetal Scalp Electrodes.


Fetal Scalp Electrodes (FSEs) are commonly used during labor to monitor the ECG of the fetus (FECG). The FSE is applied to the scalp of the fetus with the help of a torque limiting drive tube, which is a plastic tube that ensures accurate and safe application of the FSE. There is a need to accurately measure the torsional stiffness of these drive tubes during production to ensure that the risk of overtorquing the FSE and potentially harming the fetus is minimized.

The thesis will investigate how to best measure the torsional stiffness of the FSE drive tube, propose an automated measurement system and develop a prototype.

The thesis will contain:

  • Analysis of materials and properties of FSE
  • Investigation of regulatory requirements for medical device traceability and quality control
  • Specifying the device requirements together with stakeholders
  • Design and development of an automated electromechanical system for quality control of FSE

Applicants: Two master students within Electronics Engineering, Mechanical Engineering or Mechatronics.
