Extended Data Fig. 2: Fabrication and mechanical characterization of the SES.
From: Freezing droplet ejection by spring-like elastic pillars

a, Schematic illustration of the fabrication process of the SES. We fabricate the SES using the cast-molding method based on the 3D-printed masters. d and h, the diameter and height of the micropattern; w, the center-to-center spacing between the micro patterns; \({h}_{{\rm{p}}}\), the height of the pillar; \({R}_{{\rm{b}}}\), the radius of the smooth base. b, Compression tests of SES made of PDMS with different base/cross-linker ratios by weight. The compressive modulus (Kc) equals the stress value when the strain reaches 1.
