Design of products for pleasant or luxurious feeling is important within the consumer products industry, yet this is mostly still a trial-and-error activity. Friction reduction through texture is often the approach, yet the interface is complex due to multiphysical phenomena such as capillary bridges formed by sweat, deformation and contact as well as the textures ranging from macroscale to nanosc...
