Abstract
A strain gauge device for detecting force applied to a planar structure, the device including a capacitor having two spaced conductive surfaces, and a dielectric material between the conductive surfaces with a dielectric constant that varies in relation to strain force normal to the surfaces. In one embodiment, the dielectric material is realized in the form of a pair of facing linear molecule monolayers attached endwise to the respective conductive layers and oriented at an oblique angle to the layers.
