Sažetak
Compared to dye-doped elastomer actuators, the dense and regularly ordered environment in single crystals provides a platform for faster energy transfer with less energy dissipation, which directly translates into more efficient coupling between the light and mechanical energy. The general goals behind the utility of single crystals for mechanical actuation are rapid, reversible and fatigueless mechanical deformations. Fast and ultrafast mechanical responses are expected, comparable in magnitude with natural processes in human muscle fibers. Moreover, the light-driven single crystalline actuators, relative to their thermal or electrically stimulated analogues, have additional advantages: they can operate in contact-free mode under both wet and dry conditions, and they do not require large temperature or electric gradients, which turns them into attractive candidates for mechanically responsive elements in microfluidic devices. Except for microfluidic valves and gates, such technomimetic and biomimetic single crystals could be employed for light energy harvesting, as mechanically tunable optical elements, for mechanical actuation in artificial muscles, as switchable reflector elements for projective displays and for tunable contact printing.
