FIG. 7.

(a) Microscopic photograph of force-deflection measurement of PDMS micropillar using FemtoTools force sensor. (b) The pillar deflections as a function of the force applied to the 20% dye-PDMS composite micropillars. Scatter symbols represent experimental data for the colored pillars measured using FemtoTools force sensor. Solid lines are the FEA simulations in Comsol Multiphysics™ software with the value of material parameter c1 adjusted to match the measured force-deflection data (scatter plot). The inset shows a rendered image of micropillar modeled in Comsol™. The color bar indicates the displacement in x direction from 0 μm (green) to 25 μm (red).
