Zusammenfassung:	A system and method for measuring load and an additional property using a sensor gasket embedded between two components. The sensor gasket may include a sensor layer and a conductive layer. A gap between the sensor layer and conductive layer may be filled with a load sensitive material. The thickness of the load sensitive material varies with the load applied to the two components between which the sensor gasket sits. The sensor operates in a first mode to obtain a sensor measurement that depends on the distance between the sensor layer and conductive layer. The sensor measurement then used to estimate the applied load. The sensor operates in a second mode to estimate a property of one or both of the components. The property of interest may be cracking, material loss due to corrosion, temperature, or another property of the component.
