Abstract
We propose that large, reversible shape changes in solids, of between 10%-4 00%, can be induced optically by photoisomerizing monodomain nematic elasto mers. Empirical and molecular analysis of shape change and its relation to thermal effects is given along with a simple model of the dynamics of respo nse. Our experiments demonstrate these effects for the first time and theor y is compared qualitatively with our results.
