KORVEKSiS: Compensated Location Vectors for the Characterization of Seismocardiographic Signals using Integrated Sensor Technology

(Kompensierte Ortsvektoren zur Charakterisierung seismokardiografischer Signale mittels integrierter Sensorik)

Project Period: 01.07.2025 - 30.06.2028

KORVEKSiS addresses the overarching research question of how seismocardiographic signals (SCG) can be uniquely characterized with resource-limited sensor technology to offer cost-effective, portable alternatives to classical imaging methods. These alternatives aim to support diagnostics and monitoring in medical care, prevention, and health promotion.

The current project involves fusing 3D accelerometers with 3D gyroscopes to derive compensated location vectors whose orientations can be configured. This fusion allows for location-based interpretation of SCG signals based on the sensor's position.

KORVEKSiS takes into account previously neglected measurement uncertainties such as artifacts, latencies, jitter, and drift. By compensating for these factors, the derived vectors provide a more stable and standardized basis for associating characteristic cardiac physiological signals within translational models. These methods are designed with future implementation on wearable, resource-constrained systems in mind.

The work plan includes the development and evaluation of a miniaturized sensor platform integrating fused accelerometer and gyroscope technology. To address the lack of standards, a test infrastructure will be created using validated components to enable synchronized data acquisition from SCG and reference systems. Baseline data will be collected through human experiments, forming a foundational dataset for the project.

From this dataset, compensated SCG location vectors will be derived and analyzed using data from echocardiography, electrocardiography, and phonocardiography. Simultaneously, translational models will be developed, and characterization will be integrated into constrained sensing systems.

In summary, the project will deliver a robust portfolio of methods that will serve as the scientific basis for further research into cost-effective wearable technologies. These systems aim to enhance outpatient diagnostics, continuous monitoring, and personalized health promotion strategies.
