Sliding friction between the skin and a touched surface is highly complex, but lies at the heart of our ability to discriminate surface texture through touch. Prior research has elucidated neural ...

The high surface-to-volume ratio of micro- and nano-mechanical contacts greatly enhances the undesired effects of wear and frictional energy dissipation. Hence, considerations of friction reduction ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...
