木材是一种典型的生物材料，适应机械要求。纤维素原纤维的微结构决定了木质材料的机械性能，以及它们基于水的吸收和解吸的致动性能。在这里，有人认为，纤维素纤维的取向对应于一个模拟代码，确定木材作为一种活性材料对湿度的响应。木材活动的收获，以及生物灵感的例子，给出。
Wood is a prototypical biological material, which adapts to mechanical requirements. The microarchitecture of cellulose fibrils determines the mechanical properties of woody materials, as well as their actuation properties, based on absorption and desorption of water. Herein it is argued that cellulose fiber orientation corresponds to an analog code that determines the response of wood to humidity as an active material. Examples for the harvesting of wood activity, as well as bioinspiration, are given.
