Healable soft robotic systems have been developed by constructing flexible membranes out of Diels?Alder (DA) polymer networks. In these components, relatively large amounts of damage, on the centimeter scale, can be healed, provided that the temperature is increased to 80?90 ?C. This article presents a new DA polymer network that can heal at room temperature through a smart design of the network that increases the molecular mobility in the material. This new material is used to develop the first healable soft robotic prototype that can autonomously recover from severe, realistic damage. The soft pneumatic hand can recover from various types of injuries, including being cut completely in half, without the need for a temperature increase. After healing, the performance of the soft robotic prototype is recovered.

软气动机器人中的室温自我修复：Diels-Alder聚合物网络中的自主自我修复

通过利用Diels？Alder（DA）聚合物网络构建柔性膜，已经开发出了可修复的软机器人系统。在这些组件中，只要温度升高到80-90°C，就可以修复相对较大的厘米级损坏。本文介绍了一种新的DA聚合物网络，该网络可以通过网络的智能设计在室温下进行修复，从而增加材料中的分子迁移率。这种新材料用于开发第一个可修复的软机器人原型，该原型可以从严重的，实际的损坏中自动恢复。柔软的气动手可以从各种伤害中恢复，包括完全切成两半而无需提高温度。修复后，恢复了软机器人原型的性能。
