ABSTRACT:
An integrated LCC-based strain gage sensor, in which at least two LCC traces or strands run across a microcavity within the cylinder head gasket. In one aspect of the present invention, a system is provided comprising a signal source and a microcavity through which an input signal from the signal source passes and which alters the input signal as a result of a response of the microcavity to a strain. An LCC connects the microcavity and the signal source and an input signal propagates through the LCC. The microcavity may comprise one or more reflective surfaces which alters the input signal as a result of a change in a dimension of the microcavity. In another aspect of the invention, the microcavity produces an output signal that has an intensity or frequency different from that of the input signal upon undergoing a deformation.
