We investigate the electrostatic contribution to the lipid membrane mechanical parameters: tension, bending
rigidity, spontaneous curvature, and flexocoefficient, using an approach where stress in the membrane is explicitly
balanced. Our model includes an applied electrostatic potential as well as a charge distribution in the membrane.
We apply our theory to membranes having surface charges and electric dipoles at the surface.
