title = "Bioinspired micromechanical interlocking structures for enhanced adherence between soft elastomeric layers",
abstract = "Bioinspired by the role of stratum spinosum's microinterlocks in enabling firm interlayer adherence of human skin, we fabricated a highly dense 2D array of spherical microstructures with an undercut up to ~20 degrees to create microinterlocks in polydimethylsiloxane (PDMS) layers. A single bend cantilever fracture test demonstrated a 3-5 fold increase in adhesion strength compared to the plain layers and 30-35 % compared to the hemispherical counterparts without undercuts. These bioinspired microstructures could open up new potential applications in augmenting adherence between soft layers of engineered tissues and in 3D bioprinting.",
