Example Embodiment
[0033] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0034] Such as figure 1 As shown, the reversible adhesive device based on a dielectric elastomer in this embodiment includes a first fixed layer 5, an adhesion layer 4, a rigid body 3, a driving layer 2 and a second fixed layer 1, from bottom to top. A fixed layer 5 and a second fixed layer 1 are collectively referred to as a fixed layer.
[0035] Both the first fixed layer 5 and the second fixed layer 1 are provided with through holes as positioning holes to match the deformation of the adhesion layer 4 and the drive layer 2 caused by the rigid body 3; the upper and lower surfaces of the drive layer are coated with electrodes; the rigid body 3 It is a rigid steel ball with a diameter of 8mm.
[0036] The adhesive layer 4 uses acrylic pressure-sensitive adhesive. The driving layer 2 uses a dielectric elastomer with high elasticity. After the adhesion layer 4 a...
