| Abstract | Electrothermal actuators (ETAs) have been the focus of continuous R&D in targeting soft actuator applications. This article explores both the fabrication and design characteristics of a poly(dimethylsiloxane) (PDMS) elastomer—carbon nanotube buckypaper layered composite in the dual cantilever bending arrangement. Actuation characterization tests demonstrate the relationship between actuator geometries, boundary conditions, and heating rate to the maximum bending deflection. SEM observations on the cross sections of the ETAs fabricated with different conductive layers display the variations in thickness, and the effects of localized heating zones are discussed. By comparing different fabrication methods, improvements to the actuation features through ETA design modification were reported, and the possibility to greatly increase the actuation was displayed. The potential of ETAs as surface morphing actuators is demonstrated in concept through fabrication of a single sheet array consisting of multiple ETAs with the ETA segments individually and simultaneously activating to create hill-like features. |
