    摘要： A reflective strain gauge includes an holographically-formed polymer dispersed liquid crystal (H-PDLC) film comprising layers of liquid crystal (LC) droplets in a matrix polymer, the H-PDLC film having a reflection or transmission grating capable of reflecting or transmitting light of a selected wavelength, and means for adhering the film to a surface of a workpiece for monitoring the strain at said surface. A change in the nature of the reflected light is an indication of strain. Also included is a polarizing material having an holographically-formed polymer dispersed liquid crystal (H-PDLC) film comprising layers of liquid crystal (LC) droplets in a matrix polymer, the H-PDLC film having a reflection grating capable of reflecting light of a selected wavelength, wherein the reflection grating of the H-PDLC film is oriented, such that the refractive index parallel to said axis of orientation (ne) is greater than the refractive index perpendicular to said axis (no).

    摘要： A wiring harness and a touch sensor incorporating same are disclosed. The touch sensor includes a sensing electrode disposed in a touch sensitive area. The touch sensor further includes a plurality of auxiliary electrodes disposed on a self-supporting dielectric substrate in a border area. The auxiliary electrodes transmit a touch signal to electronics configured to use the touch signal to determine the touch location.
