Job description

The Electronic Systems (ES) group within the Department of Electrical Engineering of Eindhoven University of Technology (TU/e) seeks to hire an outstanding PhD candidate within the field of remote vital signs monitoring.

Project description

Commoditization of digital cameras in visibile, nIR and thermal infra-red spectral ranges has led to the discovery of a relatively large variety of techniques to measure physiological parameters in an entirely contactless manner, using these cameras. Within the UMOSA project we will explore two contactless techniques, namely speckle vibrometry and remote thermography because each has a unique measurement principle, and consequently, they provide a relatively broad range of complementary physiological parameters.

In this PhD project, you will investigate how speckle vibrometry (SV) can be used for sleep monitoring. SV is a technique in which a laser illuminates a spot on an object (e.g. the chest of a human). Images recorded with a camera and a defocused lens show a speckle pattern which is extremely sensitive for minute vibrations of the object. The technique can measure a cardio-ballistic signal from the chest or back, even when it is covered by several layers of textile. You will explore the feasibility of SV with the aim of measuring pulse transit times (PTT), combining the cardiac signal off the chest (from SV) and the PPG waveform measured with remote PPG on the face. PTT is of interest for polysomnography since it may be used as a measure for inspiratory effort in obstructive sleep apnea patients. A recent study has demonstrated that on the wrist and chest covered with textile can measure PTT with quite high precision in compliant subjects. Whether this holds true for sleep patients is an important question which you should answer in this project.

Departments and collaborators

The Electronic Systems group consists of seven full professors, ten assistant professors, several postdocs, about 40 PDEng and PhD candidates and support staff. The ES group is world-renowned for its design automation and embedded systems research. It is our ambition to provide a scientific basis for design trajectories of electronic systems, ranging from digital circuits to cyber-physical systems. The trajectories are constructive and lead to high quality, cost-effective systems with predictable properties (functionality, timing, reliability, power dissipation, and cost). Design trajectories for applications that have strict real-time requirements and stringent power constraints are an explicit focus point of the group. Within this area, G. de Haan and S. Stuijk have developed various novel remote vital signs monitoring algorithms and their embedded implementations.

The UMOSA project team is designed to combine extensive knowledge in the key fields. The project team includes partners from Philips and the Kempenhaeghe sleep hospital. As part of this project, the PhD candidate will work closely with these partners to ensure that the developed techniques are suitable for use in clinical practice.

Job requirements

We are looking for candidates that match the following profile:

  • A master's degree in Electrical Engineering or related disciplines with excellent grades.
