摘要： Highly twisted, coiled polymer actuators (TCPAs) are made by twisting polymer monofilaments in a first direction, plying the monofilaments in a second, opposite direction to form a yarn, then coiling the yarn. The resulting coil is annealed to form a functional TCPA. The disclosed manufacturing method is based on the false-twisting principle, and produce twisted filaments and twist-stable yarns continuously and rapidly. The twisted monofilaments can be associated with wires for heating and sensing. Because the yarns are twist-stable, they can be processed on standard textile machines to form contracting artificial muscles.

摘要： Polymer and nanotube-based actuators that include a thermochromic coating is disclosed. The actuators include a thermochromic material applied to a surface of the core fiber or the conductive element. Upon heating the actuator, the thermochromic coating undergoes a color transition to indicate a pre-determined temperature correlated to a rated critical temperature, important temperature of the actuator components, or a level of actuation.

摘要： Cooling by a twist-untwist process, by a stretch-release process for twisted, coiled, or supercoiled yarns or fibers, and methods and systems thereof. High mechanocaloric cooling results from release of inserted twist or from stretch release for twisted, coiled, or supercoiled fibers, including natural rubber fibers, NiTi wires, and polyethylene fishing line. Twist utilization can increase cooling and cooling efficiencies. A cooler using twist insertion and release can be shorter and smaller in volume than a cooler that requires a large elastomeric elongation. The cooler system can be utilized in mechanochromic textiles and remotely readable tensile and torsional sensors.

摘要： Reversible shape memory polymer bilayer actuators comprised of an active polyPOSS (PP) layer and a passive KAPTON layer. The PP is a unique polymeric composition which maintains its mechanical properties and coefficient of thermal expansion at elevated temperatures while adhering to the KAPTON layer. The actuator is durable to extreme conditions such as elevated temperatures and corrosive environments and maintains motion accuracy at the μm-scale.
