Self-deformable varifocal lens
Overview:
In this paper, we propose a compliant, highly transparent, and electroactive polymers based selfdeformable microlens for smart optical devices. Especially, a non-ionic PVC gel among electroactive polymers was selected to develop self-deformable microlens to avoid the solvent leakage because its actuation mechanism is not based on solvent-drag deformation but on creep deformation in an electric field, unlike ionic gel electrolytes. To make the convex shape on an actuation area of the proposed module, we put a rigid annular electrode on the electroactive PVC gel and apply pressure input by the rigid annular electrode. Later, we measure the focal length variations of the proposed varifocal lens with various thicknesses of electroactive gels.Publication:
