Developing soft actuators has emerged as one of the most promising areas in robotics, with a growing demand for tunable lenses driven by rapid advancements intelligent mobile devices and cameras. Traditional mechanical lens systems are characterized their heaviness, complexity, rigidity. To address these limitations, this research introduces novel approach: dual‐chamber liquid actuated an electrohydrodynamic (EHD) pump. The study involves fabrication planar EHD pump, experimental investigation into impact electrode gap, width, electrode‐pair gap on pump's pressure. Following optimization is constructed, comprising two chambers, rigid transparent plate, prestretched elastic membranes, which connected to pump via tubes. Additionally, mathematical model developed predict focal length lens. Both theoretical analyses conducted explore effects prestretch ratio membranes radius chambers variation. predictions length–voltage curves align closely findings, providing validation proposed model.
