Extended Data Fig. 7: Confocal images of hexagon-walled pillar-array structure at two cross sections (A and B) during loading and unloading underwater pressure.
From: Frictionless multiphasic interface for near-ideal aero-elastic pressure sensing
The green region of fluorescence signal represents water, the red signal is the reflection from the water-air interface or the water-electrode interface, and the black region is air. This series of images shows water-air interface movement during water wetting process in the hexagon-walled pillar-array structure.
