Besides their scienti c signi cance, such materials have a high innovation potential and can be found, e.g., in smart fabrics [2-4], heat-shrinkable tubes for electronics or lms for packaging [5], self-deployable sun sails in spacecrafts [6], self-disassembling mobile phones [7], intelligent medical devices [8], and implants for minimally invasive surgery [9-11]. These are only examples and cover only a small region of potential applications. Actively moving polymers may even reshape the design of products [12]. In this chapter, different classes of actively moving materials are introduced with an emphasis on shape-memory polymers. The fundamental principles of the different functions are explained and examples for speci c materials are given.
