软气动执行器的开发基于由具有嵌入式片材或纤维结构的弹性体组成的复合材料（例如，纸或织物）是柔性的但不可延展的。在气动充气时，这些致动器基于其复合结构可获得的运动而各向异性地移动。它们价格低廉，制造简单，重量轻，易于驱动。这类结构是通用的：相同的设计原理导致致动器以广泛的运动（弯曲，伸展，收缩，扭曲等）响应加压。当用于将各向异性引入到弹性体中时，纸可以容易地按照折纸的原理折叠成3D结构;这些折叠的结构增加了弹性体致动器的刚度和各向异性，同时重量轻。这些软致动器可以以中等性能操纵物体;例如，它们可以提升高达其重量120倍的负载。它们还可以与其他组件（例如电气组件）组合以增加其功能。
The development of soft pneumatic actuators based on composites consisting of elastomers with embedded sheet or fiber structures (e.g., paper or fabric) that are flexible but not extensible is described. On pneumatic inflation, these actuators move anisotropically, based on the motions accessible by their composite structures. They are inexpensive, simple to fabricate, light in weight, and easy to actuate. This class of structure is versatile: the same principles of design lead to actuators that respond to pressurization with a wide range of motions (bending, extension, contraction, twisting, and others). Paper, when used to introduce anisotropy into elastomers, can be readily folded into 3D structures following the principles of origami; these folded structures increase the stiffness and anisotropy of the elastomeric actuators, while being light in weight. These soft actuators can manipulate objects with moderate performance; for example, they can lift loads up to 120 times their weight. They can also be combined with other components, for example, electrical components, to increase their functionality.
