Abstract

The forces that arise from the presence of liquids play an important role in many systems. To investigate capillary force we have developed a measurement platform that combines the force-gradient sensitivity of atomic force microscope (AFM) with the force measuring capability of a micro-electromechanical force sensor. The hybrid AFM-MEMS scheme provides both direct and indirect information of the discontinuous as well as continuous forces associated with the water water cluster The experimental technique is described along with results showing the advantage of this approach and two simultaneously sensed signals are mutually complimentary for the guarantee of the capillary forces.
