Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to an intelligent hydrogel device and a control device thereof. Background technique [0002] Smart gel materials sensitive to electric fields can swell, shrink or bend under the stimulation of electric fields, converting electrical energy into mechanical energy. Electric field-sensitive hydrogels are generally composed of polyelectrolytes, and their responsiveness is due to the directional movement of free ions in solution under a DC electric field, resulting in uneven ion concentrations inside and outside the gel, resulting in osmotic pressure changes that cause gel deformation. When this hydrogel is placed in an electrolyte solution, under the stimulation of an electric field, the volume or switch of the gel will change, realizing the conversion from electrical energy to mechanical energy. The field of bionic materials has broad application prospects. [0003] However...

Problems solved by technology

[0003] However, the existing gels always have the problem of unsatisfactory electrical conductivity and dynamic properties, which makes the existing gels less sensitive to the electric field, which limits the scope of controlling the stress deformation of the gel.
