A pressure transducer includes a base ply (12), a resistance ply disposed on the base ply and at least two spaced apart con- ductors (26, 28) juxtaposed in relation to the resistance ply whereby at lea st one of the conductors may be pressed against the re- sistance ply. The resistance ply is made by spraying or silk screening a mixture of a continuous matrix conductive resin (18) and a stannous oxide particulate (16) and then curing the composition to form a solid resistance ply having a surface with a multiplicity of micro-protrusions formed by the stannous oxide particulate.
