Abstract
A touch-sensitive assembly and method of making includes a first electrically conductive layer disposed on a first substrate and a second electrically conductive layer disposed on a second substrate. A piezoelectric film is disposed between the first electrically conductive layer and the second electrically conductive layer. The piezoelectric film includes a plurality of aligned piezoelectric particles disposed in a polymeric matrix and is characterized by a haze value of about 5% or less.
