This study presents a novel fabrication process for patient-specific bifurcated arterial phantoms integrated with electroactive polymer actuators enabling active control of internal geometries. Device fabrication is achieved via direct ink writing of PDMS within a support bath, resulting in the desired high-resolution 3D structure. Particle image velocimetry techniques are subsequently employed to characterize the flow within the phantom. Actuating the phantom simulates the impact of stenosis and dilation on the arterial flow characteristics.
