Abstract

The present disclosure generally relates to a multilayer extendable actuator. The actuator comprises: a first stiffening elastomeric layer; a second stiffening elastomeric layer; a set of middle layers disposed between the stiffening elastomeric layers, the middle layers comprising an elastic elastomeric layer that is more elastic than the stiffening elastomeric layers; and a set of grooves through one or more of the elastomeric layers, the grooves arranged such that a cross-section of the elastomeric layers comprises a wave profile around the grooves, wherein the actuator is extendable such that the elastomeric layers along the wave profile become alternatingly arranged along the extended actuator.
