Scanning electron micrograph of mushroom-shaped adhesive microstructure (MSAMS). Inset shows an individual MSAMS in contact with smooth glass substrate. SH, shaft; CL, contact lip; NN, narrowed neck.
Results obtained in adhesion and friction experiments with MSAMS and a smooth control made from the same material. (a) Pull-off forces measured at different retraction velocities and different ambient pressures on smooth glass substrates.16 (b) Evolution of adhesion strength of oil-wetted MSAMS on smooth (upper plot) and rough (lower plot) substrates. Straight lines represent the dry adhesion level.17 (c) Friction forces of MSAMS and smooth control as a function of lateral displacement measured on smooth glass substrates with a preload of 40 mN.18
