Abstract
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.
