Miniaturization of image sensors and increase of their resolution creates a demand for new miniature optical
components providing classical functions in optics, like auto-focus (AF) and optical image stabilization (OIS).
Several routes have been explored in order to realize AF and OIS functions in miniaturized components, for
example electro-wetting liquid lenses, MEMS components and liquid crystal (LC) lenses. Our recent attempt to
provide OIS with LC lenses showed the possibility to shift an image but limitations appeared. The sectorization
of the electrodes generates aberrations due to the discontinuities of the electric field at the junction between two
sectors. To overcome these limitations, we propose a new structure featuring a resistive electrode. This structure
consists in substrates with thin electrodes joined with a ring-shaped resistive electrode (10kΩ/sq.) made of
PEDOT-PSS and etched by oxygen plasma. A high resistivity layer (10MΩ/sq.) is then coated on the optical
aperture and the cell is assembled like a classical LC modal lens. With this electrode structure, we succeeded
to linearize the electric potential between the electrodes and reduce aberrations of the resulting wavefronts.
First we simulated the lens by finite elements method to study the impact of the ring-shaped resistive electrode
and to calibrate the physical parameters of each components (metallic electrodes, ring-shaped electrode, high
resistivity layer, LC...). Then, we realized lenses and we characterized them in terms of focus, deviation angle
