Movie S8.

This video includes a gallium-based LCE composite, rather than EGaIn. The composite can be frozen to solidify the gallium microparticles, which rigidifies the composite. The composite can be heated above the transition temperature of gallium but below the transition temperature of the LCE matrix to allow the composite to stretch. By heading above the transition temperature of the LCE, the composite can actuate. Gallium particles can be selectively melted by Joule-heating to produce unique shape-morphing like bending and buckling shown in the example in the video.
