Abstract
The artery vessel simulator mimics the pulse using a membrane pump to drive water flow through the PDMS phantom intermittently to simulate the blood flows in the artery vessel. The DIC method performs the evaluation, where the images used for DIC calculation are captured by a single-camera stereo-imaging system, which can eliminate the time synchronization issue. The fluorescent medicine FITC is used to generate the random patterns on the surface of a PDMS phantom, where the PDMS phantom is part of the artery vessel simulator. The DIC method determines the displacement and strain field introduced by the interaction between water and the PDMS phantom to know the mechanical behavior of the simulator. In this study, two different imaging modes are implemented to see the time various mechanical behavior of water-PDMS phantom interaction and the simulator’s stability. Some challenges for using FITC to the PDMS would be highlighted at the end of this paper.
