Introduction to Artificial Blood: Rheological Characterization of Blood-Mimicking Materials

Accurate blood-flow models are essential for many cardiovascular research applications. Optical tracing techniques such as Particle Image Velocimetry (PIV), however, often rely on simplified single-phase glycerin/water substitutes, which can limit how accurately the flow behavior of blood is represented.

In this webinar, we introduce a multiphase blood substitute developed for PIV measurements. The system uses hydrogel microparticles made of poly-sodium acrylate-co-acrylamide (P(SA-Am)) to mimic key aspects of artificial erythrocytes and enable more representative flow experiments.

The presentation focuses on the fabrication and rheological and tribological characterization of these artificial blood components, providing insights into how material properties can be tailored for use in experimental blood-flow models.

The work is part of a cooperation project with the Institute of Machine Design and Tribology and the Institute of Multiphase Processes at Leibniz University Hannover.

Join us to explore how rheological characterization can support the development of more realistic blood-mimicking materials for biomedical research.
