オジギソウの膨圧運動の再現を目指した流体ソフトアクチュエータ

－第２報：刺激信号を伝える流体回路－

抄録

We propose a fluid soft actuator that imitates the structure of the mimosa pudica. The mimosa pudica releases Ca2+ into cells when stimulated from the outside. The leaves can be closed by using Ca2+ as a trigger to change the amount of fluid inside the cell. In addition, the leaves can be opened again by restoring the amount of fluid over time. We propose the fluidic circuit that transmits stimulation signals, based on the signal transmission function of the mimosa pudica. Also, we propose the structure of the actuator that closes in response to a stimulation signal and returns to the open state over time. Finally, we examine the validity of the proposed method by experiments.
