The fabrication of hollow and multicomponent micro‐objects with complex inner structures using state‐of‐the‐art subtractive, formative, and additive manufacturing technologies is challenging. Controlled shape transformation offers a very elegant solution to this challenge. While shape transformations on macroscale can be achieved using either manual or automatic manipulation, shape transformations on microscale can better be realized using shape‐changing polymers such as hydrogels, shape‐memory polymers, liquid crystalline elastomers, and others. This review discusses the properties of different classes of shape‐changing materials, the principle of shape transformation, possibilities to achieve complex shape transformation, as well as applications of shape‐changing materials in microfabrication and other fields.

使用形状转换软材料进行微细加工

使用最新的减法，成形和增材制造技术制造具有复杂内部结构的中空和多组分微物体具有挑战性。受控的形状转换为应对这一挑战提供了非常优雅的解决方案。虽然可以使用手动或自动操作来实现宏观上的形状转换，但使用可变形聚合物（例如水凝胶，形状记忆聚合物，液晶弹性体等）可以更好地实现微观上的形状转换。这篇综述讨论了不同种类的形状改变材料的特性，形状变换的原理，实现复杂形状变换的可能性以及形状改变材料在微细加工和其他领域中的应用。
