Responsive polymer-based materials can adapt to their surrounding environment by expanding and shrinking. This swelling and shrinking (mechanotransduction) can result in a number of functions. For example, the response can be used to lift masses, move objects, and can be used for sensing certain species in a system. Furthermore, responsive polymers can also yield materials capable of self-healing any damage affecting their mechanical properties. In this chapter we detail many examples of how mechanical responses can be triggered by external electric and/or magnetic fields, hygroscopicity, pH, temperature, and many other stimuli. We highlight how the specific responses can be used for artificial muscles, self-healing materials, and sensors, with particular focus on detailing the polymer response yielding desired effects.
基于响应性聚合物的材料可以通过膨胀和收缩来适应其周围环境。这种膨胀和收缩（机械转导）可以产生多种功能。例如，这种响应可用于提升重物、移动物体，还可用于检测系统中的某些物质。此外，响应性聚合物还能产生能够自我修复任何影响其机械性能的损伤的材料。在本章中，我们详细介绍了许多通过外部电场和/或磁场、吸湿性、pH值、温度以及许多其他刺激来触发机械响应的例子。我们重点介绍了如何将特定响应用于人造肌肉、自我修复材料和传感器，特别着重于详细说明产生所需效果的聚合物响应。
