Internship | Comparing a newly developed wearable optic device to current optic
About this position
Using hybrid printed electronics technique, Holst Centre has developed a wearable optical sensor by integrating silicon photodiodes with multiple light sources and readout electronics into a lightweight and flexible patch. By recording optical signals from the skin using light sources with different wavelengths, our patch simultaneously measures signals from different skin depths. This provides advantages to overcome significant challenges in the field. Our current R&D is focused on photoplethysmography (PPG) by recording optical signals from the illumination of the human tissue. Morphological features from the PPG signal can be translated into cardiovascular parameters of interest such as heart rate, heart rate variability, respiratory rate and oxygen saturation (SpO2).
What will be your role?
Working in an interdisciplinary team of engineers and scientist (electrical engineering, material science, biomedical photonics) you will measure and analyse PPG signals using Holst Centre’s wearable optical sensor patch and existing software platforms. The challenges reside in:
- Obtaining reliable PPG signals and extracting morphological features from them;
- Linking them to existing physical conditions of individuals, in particular with an interest in cardiovascular diseases (CVDs).
- Gain a basic understanding of biomedical optics and of propagation of the light in the human tissue;
- Provide a literature review on commercial, FDA approved and clinical/gold standard research tools detailed within academic papers for comparison of optical devices;
- Determine methodologies used for assessment/comparison of PPG signals within literature;
- Acquire PPG signals with Holst Centre’s wearable optical patch and compare devices within specific methodologies;
- Communicate via presentations and report writing findings.
What we expect from you
As a team member your tasks will be:
- Knowledge acquisition through literature survey, discussion with other team members, and internal seminars/colloquiums;
- Data acquisition through measurements;
- Analysis and presentation of experimental data;
- Documentation of results in a technical report or scientific publication;
- Presentation of results in internal seminars/colloquiums.
