Abstract
A method of generating a coiled actuator fiber that includes twisting a fiber to generate a twisted fiber; wrapping the twisted fiber around a core yarn or fiber to generate a coil in the twisted fiber, which generates a coiled twisted fiber; setting the coiled twisted fiber by heat or chemical treatment; and removing at least a portion of the core yarn or fiber to generate a coiled actuator fiber.
Claims20
A method of generating a coiled actuator fiber comprising:
- twisting a fiber to generate a twisted fiber;
- wrapping the twisted fiber around a core yarn or fiber to generate a coil in the twisted fiber, which generates a coiled twisted fiber;
- setting the coiled twisted fiber by heat or chemical treatment;
- and
- removing at least a portion of the core yarn or fiber to generate a coiled actuator fiber.

A method of generating a coiled actuator fiber comprising:
- twisting a fiber to generate a twisted fiber;
- coiling the twisted fiber to generate a coiled fiber;
- and
- setting the coiled fiber by heat or chemical treatment to generate a coiled actuator fiber,
- wherein the coiled actuator fiber comprises a thermal expansion coefficient having a magnitude of 2 mm/m/° C. or more, and
- wherein the coiled actuator fiber defines space between neighboring coils of the coiled actuator fiber such that thermal actuation of the coiled fiber actuator brings the neighboring coils into contact with each other above 10° C.
3 more elements
A method of generating a coiled actuator fiber comprising:
- generating a coiled actuator fiber having coils that define physical space between the coils when:
- a. the coiled actuator fiber is at 27.0° C. and
- b. is unloaded, and
- setting the coiled fiber actuator by at least one of either:
- a. heat or
- b. chemical treatment,
- while the coiled actuator fiber is under physical constraint that prevents actuation of the coiled actuator fiber during the setting.
