There is a great deal of interest in the Casimir force due its connection with quantum fluctuations, dark energy and nanotechnology applications. Measurements in plate geometry are limited to a distance of 0.5 microns due to parallelism. This can be overcome by the use of a multilayer system which is parallel to a high degree and allows plate separations of less than 10 nm to be explored. The Casimir force would be measured by switching the electrical conductivity of one Caismir plate from a metal to an insulator and measuring the change in d-spacing of a soft insulating layer.
