Physical model of PDMS invasive growth. a Schematic of the physical model. The distance probe traveled is d; F is the force detected by the sensor; L is the PDMS length, and R is the PDMS radius. b Image of the physical model setup. Force sensor attached to 1-mm-diameter probe (left) and PDMS on the right as indicated in a. c Shape of the steel probe tip. Probe is 1 mm diameter. d PDMS penetration. PDMS (40:1; Young’s modulus ~ 100 kPa) cylinder (1.75 cm length and radius) with 1 mm probe displacement of 1.6 μm/s. Upper image, prior to rupture of PDMS; lower image, probe exit from PDMS
