软质材料可以根据湿度可逆地改变形状，在软机器人和生物医学等各个领域都有应用。然而，这种湿度响应材料的结构可变形或机械自修复版本的设计仍然具有挑战性，它可以任意改变形状并重新配置其3D结构。在这里，通过从共价-非共价网络中汲取灵感，开发了一种精心设计的生物聚酯，其特点是简单的吸湿驱动机制，在低环境温度下可直接制造(
Soft materials that can reversibly transform shape in response to moisture have applications in diverse areas such as soft robotics and biomedicine. However, the design of a structurally transformable or mechanically self-healing version of such a humidity-responsive material, which can arbitrarily change shape and reconfigure its 3D structures remains challenging, Here, by drawing inspiration from a covalent-noncovalent network, an elaborately designed biopolyester is developed that features a simple hygroscopic actuation mechanism, straightforward manufacturability at low ambient temperature (
