Soft pneumatic actuators based on composites consisting of elastomers
with embedded sheet or fiber structures that are flexible but not
extensible combine soft lithography, for fabrication, with the
principles of origami, for structural design. These actuators respond to
pressurization with a wide range of motions, such as bending,
extension, contraction, and twisting. (Credit: Ramses V. Martinez et
