Abstract

Official abstract text for this publication.

Actuators (artificial muscles) comprising twist-spun nanofiber yarn or twist-inserted polymer fibers generate torsional and/or tensile actuation when powered electrically, photonically, chemically, thermally, by absorption, or by other means. These artificial muscles utilize non-coiled or coiled yarns and can be either neat or comprising a guest. Devices comprising these artificial muscles are also described.

First claim

Opening claim text (preview).

What is claimed is: 1. A non-electrochemical actuator comprising: (a) a first actuating twist-spun nanofiber yarn segment that comprises nanofibers and an actuating yarn guest that is operable for undergoing substantial change in volume by a change process selected from the group consisting of heating, exposing to radiation, exposing to a chemical or chemical mixture, and any combination thereof, wherein said first actuating twist-spun nanofiber yarn is either non-coiled or coiled…
