Biomimetic materials that use natural wisdom to solve practical problems are developing rapidly. The trend for systematic biomimicry is towards in-situ characterization of natural creatures with high spatial resolutions. Furthermore, rapid reconstruction of digital twin models with the same complex features as the prototype is indispensable. However, it faces bottlenecks and limits in fast characterization and fabrication, precise parameter optimization, geometric deviations control, and quality prediction. To solve these challenges, here, we demonstrate a state-of-the-art method taking advantage of micro-computed tomography and three-dimensional printing for the fast characterization of the pitcher plant Nepenthes x ventrata and fabrication of its biomimetic model to obtain a superior drainage controller with multiscale structures with precise surface morphology optimization and geometric deviation control. The film-rupture-based drainage dynamic and mechanisms are characterized by x-ray and high-speed videography, which determines the crucial structures for unique directional drainage. Then the optimized artificial pitchers are further developed into sustained drainage devices with novel applications, such as detection, reaction, and smoke control.

通过系统仿生学控制排水的三维多尺度水罐的快速原型和快速构建

利用自然智慧解决实际问题的仿生材料正在迅速发展。系统仿生学的趋势是原位具有高空间分辨率的自然生物特征。此外，快速重建与原型具有相同复杂特征的数字孪生模型也是必不可少的。然而，它在快速表征和制造、精确参数优化、几何偏差控制和质量预测方面面临瓶颈和限制。为了解决这些挑战，我们在这里展示了一种最先进的方法，利用微型计算机断层扫描和三维打印来快速表征猪笼草猪笼草X文特拉塔并制作其仿生模型，以获得具有多尺度结构的优越排水控制器，具有精确的表面形貌优化和几何偏差控制。基于薄膜破裂的排水动力学和机制通过 X 射线和高速摄像进行表征，这确定了独特定向排水的关键结构。然后，优化后的人工投手进一步开发成具有检测、反应、烟雾控制等新颖应用的持续排水装置。
