Dielectric elastomers (DEs) actuated
via
the space charge mechanism are characterized by low driving electric fields (2−10 V/μm) and geometry-dependent actuation modes. Liquid crystalline dielectric elastomers (LC-DEs) leverage shape changes induced by thermo-responsive order-disorder transitions to alter their actuation mode with temperature. However
such systems are currently limited to thermal responsiveness and exhibit only two actuation modes-a constraint that stands in stark contrast to the flexibility and diverse actuation capabilities of natural muscles. To overcome this limitation
we present an azobenzene-based liquid crystalline dielectric elastomer (A-LC-DE) capable of multimodal actuation
enabled by its dual thermo- and photo-responsive shape-changing properties. The incorporation of azobenzene moieties allows for mesogen alignment
via
light attenuation during photo-inhibited network formation. Thi
s facilitates programmable thermo-responsive shape changes by varying the irradiation conditions during synthesis
thereby enabling two distinct dielectric actuation modes upon heating and cooling. Furthermore
the
trans
-
cis
photoisomerization of azobenzene endows the A-LC-DE with dynamic
light-responsive shape-changing behavior. This capability allows for the creation of diverse and reconfigurable actuation modes through spatially localized irradiation. As a result
our A-LC-DE exhibits multimodal electrical actuation that can be selectively guided by external thermal and optical stimuli
promising enhanced adaptability for future soft robotic systems.
