We observed that the range of force-dependent contact angles obtained numerically for the EGaIn microdroplets θ num = 139-144 • in air (Fig. ) and θ num = 161-177 • in ethanol (Fig. ) are in agreement with those measured optically for millimetric-sized droplets (Fig. ). EGaIn is highly non-wetting when submerged in ethanol, and this explains why r is consistently smaller in ethanol (Fig. ) than in air (Fig. ). The different wetting properties in air and in ethanol also result in qualitatively different response of r to an increasing indentation depth δ and applied force F .
