COMPOSITE TRANSPARENT PRESSURE SENSING FILM

摘要

A composite transparent pressure sensing film is provided having a matrix polymer wherein the matrix polymer is a combination of 25 to 75 wt％of an alkyl cellulose and 75 to 25 wt％of a polysiloxane; and, a plurality of hybrid particles, wherein each hybrid particle in the plurality of hybrid particles, comprises a plurality of primary particles bonded together with an inorganic binder; wherein the plurality of hybrid particles are disposed in the matrix polymer; wherein an electrical resistivity of the composite transparent pressure sensing film is variable in response to an applied pressure having a z-component directed along the thickness of the composite transparent pressure sensing film such that the electrical resistivity is reduced in response to the z-component of the applied pressure.
