Bilayer model. a Schematics of the geometry of the bilayer model, with an external layer with elasticity \(E_0\) and thickness \(d_0\) and a bulk substrate with elasticity \(E_b\), indented with a sphere of radius R. b Elasticity spectrum (blue dots) calculated from numerical data for a bilayer with \(E_0\) = 9.8kPa, \(d_0\) = 300nm and \(E_b\) = 8.4kPa indicated by the black dotted lines. The solid red line represents the exponential fit that returns the values \(E_0\) = 9.77kPa, \(d_0\) = 302nm and \(E_b\) = 8.39kPa
