TRANSPARENT PRESSURE SENSING FILM COMPOSITION

摘要

A transparent pressure sensing film composition is provided having a matrix polymer; and, a plurality of conductive particles; wherein the matrix polymer comprises 25 to 100 wt％ of an alkyl cellulose; and, wherein an electrical resistivity of the transparent pressure sensing film is variable in response to an applied pressure having a z-component directed along the thickness of the transparent pressure sensing film such that the electrical resistivity is reduced in response to the z-component of the applied pressure.
