Abstract
Several instrumental developments to examine the rheol. of ultrathin confined liqs. are described. These include capacitance sensing of the film thickness, concurrent measurement of normal and shear forces by piezoelec. methods, application of periodic forces in the normal direction to det. dynamic oscillatory shear moduli, and quantification of app. misalignment. The method to sep. app. from sample contributions is stressed.
