Nature always has a lot of inspiration in the development of artificial materials. In this nature, we can see some microorganisms or plants and animals with a helix structure, which have a unique characteristic of chirality and play an important role in them. Such a helix structure can be realized by using a stimuli-responsive hydrogel having flexibility and biocompatibility and capable of reversible expansion and contraction due to external stimuli such as electricity, temperature, and pH. In this presentation, we describe the fabrication of helixs with a width of about 80 micrometers using soft thermoresponsive hydrogels and rigid polymers, and their 3D shape transformation according to their geometric parameters. The 3D shape design using hydrogel shows the possibility of soft robotics along with the development of soft materials. |
