A chest based photoplethysmography device

At imec, Biomedical Applications & Systems

Oxygen saturation is an important clinical measure in several respiratory diseases. Oxygen saturation is typically measured using photoplethysmography at the finger. The aim of the product is to develop a chest-based oxygen saturation device, using existing hardware as a basis.

 

Project Description

Oxygen saturation is an important clinical measure in several respiratory diseases like chronic obstructive pulmonary disease (COPD), asthma and sleep apnea. The wellbeing of the patients is related to the oxygen saturation level in the blood.  Oxygen saturation is often measured during a spot check using photoplethysmography at the finger. Here, we aim to develop a chest-based oxygen saturation device that will allow for longer-term monitoring in a mobile environment. The sensor will be combined with additional sensors like ECG to provide detailed disease insights.

 

The project will comprise of different phases, starting with selection and testing of PPG modules. Next, experiments should be designed and data should be collected from human subjects. An algorithm needs to be developed to convert raw sensor data to oxygen saturation levels. Finally the methods and algorithms need to be tested and validated.

 

During the project intermediate presentations to the team are expected. Depending on the results a report or paper should be written.
