Problems solved by technology

Among them, the electric driving method mainly uses two kinds of driving materials, ionic electroactive polymer and non-ionic electroactive polymer. The ionic electroactive material needs to be packaged before driving, which reduces its flexibility and is not conducive to deformation; Active polymers often require high driving voltage, which greatly limits their application range

The thermal driving method relies on the driving force generated by the thermal deformation of the driving material, so the response is slow
