| Outline of Final Research Achievements |
The aim of this study is to establish a technology to form complicated three-dimensional structures by self-folding of stimuli-responsive swelling/shrinking hydrogel microfibers. Using microfluidic devices, hydrogel microfibers where stimuli-responsive materials were spatially patterned were fabricated. By stimulating those microfibers by changing temperature or pH, we successfully demonstrated spring-shaped soft actuators that largely expands and contracts, tubular micropumps that can deliver liquid inside, and artificial muscle actuators composed of bundled microfibers.
