(a) An out-of-plane force exerted on an elastic substrate covered by a membrane. (b) Deformation profile of the membrane-covered elastic substrate in the absence of surface stress. The thickness of the substrate is 15 μm and the liquid tension γl is 50 mN/m. The equivalent thickness λ of the membrane varies from 1 μm to 104 μm.
