Abstract
A method and sheet-like sensor for measuring stress distribution including a grid of members which change in resistance when subjected to strain, the members intersecting at internal nodes and intersecting at boundary nodes at the periphery of the grid defining a plurality of legs. An analyzer is electrically connected only to the boundary nodes and configured to calculate any change in resistance in all of the legs based solely on the measured resistance of the legs between the boundary nodes.
