1. A sensor panel for sensing a load superimposed on one face of said panel, the panel comprising:

  • (a) a plate member having two faces defining therebetween the thickness of said panel,(1) each of said faces having a width and length greater than said thickness,(2) said plate member consisting essentially of an electrically conductive material varying in electric conductivity in response to pressure applied to said plate member in the direction of said thickness;

    (b) a first group of conductors elongated in a common first direction and transversely spaced from each other;

    (c) a second group of conductors elongated in a common second direction and transversely spaced from each other,(1) said groups being respectively secured to said faces in electrically conductive contact,(2) said first a second directions being angularly offset from each other.
