Abstract
Transparent nanocomposites may be used as force sensing materials, either as a transparent piezo-resistive material for resistive force sensing or a transparent dielectric material for capacitive force sensing. The common aspect of these nanocomposites is to engineer the refractive index of the binder to the index of the fillers so that when incorporated into a force sensor the nanocomposite films are optically transparent.
