Extended Data Fig. 3: µ-CT imaging of internal volume changes in MUSAS with varying angles of lamella orientation and row numbers, adhering to soft substrates with distinct stiffness and roughness.
From: Mechanical underwater adhesive devices for soft substrates
a, Setup of µ-CT imaging (scale bar: left, 1 cm; right, 5 mm). b, Representative image of suction marks left by MUSAS after adhesion to pig stomach tissue, demonstrating non-homogeneous substrate morphing. c,d, Relative vacuum ratio (c) and relative compression ratio (d) of different MUSAS designs adhering to representative soft substrates with distinct stiffness and roughness (n = 3 substrates, error bars represent mean ± s.d.; colour bars represent surface height). e, Representative µ-CT imaging of MUSAS with varying lamella orientation angles and row numbers, adhering to soft substrates with distinct stiffness and roughness. The red box represents the non-vacuum area AInitial or AAdhesion (scale bar: 5 mm).
