Characterization of strain transfer from silicone to gel surface demonstrates minimal loss. Consistent strain transfer was observed for commercially available silicone membranes (HT-6240) in both macroscale and microscale tests. While small but statistically significant losses were observed for macroscale strain of custom-made membranes (Sylgard 182), microscale calibration shows complete strain transfer in both the axial and transverse directions. (*p < 0.05 for one-sided t- test against hypothesized 100% strain transfer depicted as dashed line)
