Performance Analysis of Gyroscope for BCG/SCG Measurement

• Typ der Arbeit: Forschungsprojekt
• Status der Arbeit: abgeschlossen
• Betreuer: Ulf Kulau

For the measurement of SCG and BCG signals usually accelerometer are used. However, many works also use sensors for angular velocity, e.g. gyroscopes.

In future SCG and BCG research, gyroscopes can be very useful. While work exists using gyroscopes to measure SCG and BCG, it is not clear what properties the sensors must have for such a measurement.

For this reason, this paper will fundamentally investigate which gyroscopes are suitable for measuring SCG/BCG. Finally, a concept for the selection of suitable sensors will be derived from the relevant parameters.

Picture shows the principle of SCG/BCG measurement by using accelerometers and gyroscopes (source: Performance analysis of gyroscope and accelerometer sensors for seismocardiography-based wearable pre-ejection period estimation)

Tasks

• Paper study - to take up the information from previous research and gather useful data, ranges, and other useful set of parameters.
• Selection of potential suitable devices - selection of gyroscope sensor based on the project requirement mentioned in section scope of work.
• Implementation prototype including di↵ sensing etc.
• Evaluation - Suitability of gyroscope sensor for BCG/SCG measurement, ways to evaluate sensitivity in general (resting with enough damping material - to analyse noise). Additionally we would look up for latency in data transmission through interface i.e. I2C/SPI, also while using internal filters. Also for final evaluation of system two different types of sensors will be selected, would check which sensor result in fruitful data.
• Summary of investigation and comparison between different gyroscope sensor devices.
