Abstract：
One of the key problems in active materials is the control of shape through actuation. A fascinating example of such control is the elephant trunk, a long, muscular, and extremely dexterous organ with multiple vital functions. The elephant trunk is an object of fascination for biologists, physicists, and children alike. Its versatility relies on the intricate interplay of multiple unique physical mechanisms and biological design principles. Here, we explore these principles using the theory of active filaments and build, theoretically, computationally, and experimentally, a minimal model that explains and accomplishes some of the spectacular features of the elephant trunk.

活性材料中的关键问题之一是通过致动控制形状。这种控制的一个有趣的例子是象鼻，一个长,肌肉，和具有多种重要功能的极其灵巧的器官。象鼻是生物学家着迷的对象，物理学家,和孩子一样。它的多功能性依赖于多种独特的物理机制和生物设计原理的复杂相互作用。这里,我们使用活性细丝的理论来探索这些原理，理论上,计算上，通过实验，一个最小的模型，解释和实现一些壮观的大象鼻子的特点。
