Project Description

The SINDynamik project aimed to develop a new measurement system proto-type to enable the electrical measurement of cardiac dynamics at individual body points (e.g. wrist, arm, or chest point) through the non-invasive, simultaneous determination of the real-time dynamics of central venous pressure (CVP), electrocardiogram signal (ECG) and arterial blood pressure.

Among the partners listed above, the task of our institute was sensor optimization and modeling for the measurement with highly sensitive sensors on the patients' skin for the detection of pathological conditions of the heart (SEMOPAZU). The two main tasks here were, on the one hand, the development and construction of a laboratory setup and the parallel establishment of a simulation environment in the Comsol Multiphysics software and, on the other hand, the creation of a basic understanding of the mechanical and electrical signal components in the real recorded patient data.

In the course of the project, a multi-layer sensor system with multifunctional sensor technology was also developed and manufactured in the institute's cleanroom. The sensor system is realized in thin-film technology on flexible polymer substrates. It can be completely supplied with energy via the "near-field communication" (NFC) functionality of a mobile phone and read out dynamic data on cardiac dynamics wirelessly at a high data rate.

After completion of the project, there will be further opportunities for additional sensor functionality and embedding in contactless patient monitoring for the medical patient care of the future.
