Figure 6. Characterizations of the c-PCL. (A) Strain-stress curves of c-PCLs with different pore sizes; (B) Tactile sensitivity and (C) sensing range under normal loads for c-PCLs with different pore sizes; (D) Compressive and (E) shear stress-strain curves of the c-PCL and the schematic illustration of the testing conditions. c-PCL: Porous compressible layer.
