On the use of liquid bridges as accelerometers

Abstract

The shape of the interface of a drop of liquid held by surface tension forces between two solid disks,a liquid bridge, depends on the geometry of the supporting disks, the volume of liquid and the external forces acting on the drop. Therefore, once the geometry of the supporting disks and the volume of liquid are fixed, and assuming that the value of the surface tension is known, a way to measure such external forces could be by measuring the deformation of the liquid bridge interface.
