specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 ~ Figure 3 To illustrate this embodiment, a forward and reverse superplastic bulge forming method with variable friction conditions in this embodiment is accomplished in the following way: a. pre-stretching two dielectric elastomer films 1; b. 2 Fold in half, press out the crease, then restore, and then take the respective centers of the two films 2 as the center of the circle, and cut out a circular hole 2-2 with a radius of 5 cm; c, the two pre-stretched dielectric elastomer films 1 respectively attached to the inner surfaces 2-1 of the two films 2, under the action of the restoring force of the dielectric elastomer film 1, the films 2 stand up at right angles along the creases, and each dielectric elastomer film 1 A 1 / 4 spherical film 1-3 is formed at the round hole 2-2 of each film 2; d, coating the first electrode on the inner and outer surfaces of the 1 / 4 spherical film 1-3 of the two dielectric elastomer films 1...

specific Embodiment approach 2

[0008] Specific embodiment two: the difference between this embodiment and specific embodiment one is: in this embodiment, in step a, two dielectric elastomer films 1 are stretched transversely and longitudinally at the same time. The elongation ratio was 6.5. The requirements for voltage are greatly reduced, the flexibility is good, and the biocompatibility is excellent.

specific Embodiment approach 3

[0009] Embodiment 3: The difference between this embodiment and Embodiment 1 is that in this embodiment, in step a, the thickness of the two dielectric elastomer films 1 is 0.1mm-1mm. Better flexibility, lower driving voltage required, and better biocompatibility.
