During this presentation, I will demonstrate the propagation of embolism within a more complex biomimetic network that emulates diverse leaf venation patterns. By adjusting the sizes of constrictions and coordinating the network, we can faithfully replicate the primary characteristics of embolism development observed in natural leaves. These features include intermittency, trajectory patterns and hierarchical structures, which we can replicate through both experimental and numerical methods. To conclude, we will explore the significance of our approach in terms of materials and structure in real plants.
