Soft actuators for adaptive microlenses suffer from high input voltage, lower focal length change, slow response time. In this study, we fabricate lens using synergistically plasticized polyvinylchloride (PVC) gel and we compress the smooth gel between to sets of annular electrodes to make biconvex microlens. Synergistically plasticized polyvinylchloride (PVC) gel can deform shape under electric field along the optical path. Each surface of dual-curvature microlens can be independently adjusted to focus or scatter light to capture real or virtual images, yield variable focal lengths (+31.8 to -11.3 mm), and deform to various shape to improve aberrations. In addition to simple fabrication, our microlens operates silently, fast (0.4s under 400V) and consume low power (0.52mW), making them superior to existing microlenses. |
