Abstract :
A new method for measuring dynamic shear force called fiber wobbling method has been developed. This method enables us to clarify nanotribological properties of a confined lubricant at a high shear rate. The method shows that the viscosity of the lubricant confined at the gap of less than 10 nm is higher than that of the bulk lubricant.
