Abstract :
A nanofibrous hydrogel actuator that generates bending and stretching motion in response to pH was achieved. The gel was composed of electrospun nanofiber synthesized by copolymerizing pH responsive acrylic acid and hydrophobic butyl methacrylate. In order to control the motion of the gel actuator, we introduced an anisotropic structure into the gel by controlling the flow rate of electrospining. As a result, the gel actuator showed pendulum-like motions by fixing on the edge of the gel.
