Abstract
A panel includes a plurality of integrated strain gauges for measuring deformation information relating to the panel. The strain gauges are arranged parallel to one another in the longitudinal direction of the panel and have at least two different lengths.
Claims14
A panel comprising:
- a plurality of integrated strain gauges configured to measure deformation information relating to the panel, the plurality of integrated strain gauges having a plurality of pairs of strain gauges,
- wherein the strain gauges are arranged parallel to one another and extend in a longitudinal direction of the panel,
- wherein each pair of strain gauges include equal length strain gauges symmetrically arranged on opposite sides of a centerline of the panel,
- wherein each pair of strain gauges has a different length from each other pair of strain gauges, and
- wherein the lengths of the plurality of strain gages increase with decreasing distance from the centerline.

A device for determining deformation information for a panel to which a load is applied, the device comprising:
- a plurality of integrated strain gauges for measuring deformation information relating to the panel,
- wherein the strain gauges are arranged parallel to one another with respect to a longitudinal direction of the panel, and wherein the strain gauges have at least two different lengths;
- wherein pairs of the plurality of strain gauges extend symmetrically in the longitudinal direction with respect to a centerline of the panel, and wherein the strain gauges of each pair are equal length strain gauges symmetrically arranged on opposite sides of a centerline of the panel;
- wherein the device is configured to establish at least one item of deformation information for deformation caused by the load in a transverse direction of the panel based on a comparison of extension information determined by the pairs of the plurality of strain gauges.
