The invention belongs to the field of hydrogel actuators, and provides an application of a chitosan-gelatin composite hydrogel actuator intelligent valve. With anisotropic chitosan aerogel as the backbone and gelatin hydrogel as the muscle, synergistically acting within the actuator framework, a heterogeneous hydrogel actuator with excellent mechanical properties and multi-solvent responsiveness was constructed. The hydrogel actuator is used as a smart microfluidic valve, which can identify specific fluid flow and can adjust the flow. This invention provides a simple and green method for building responsive hydrogels, heralding its application in smart Prospects for applications in actuators, soft robotics, microfluidics, and intelligent human-machine interfaces. |
