A structural health monitoring system for multiple layer structures includes a plurality of strain-sensitive magnetic particles dispersed within a bonding area between at least two individual layers, at least one multiferroic sensor dispersed on a surface of the multiple layer structure, proximate to an area of the structure to be monitored, the at least one multiferroic sensor capable of monitoring strains experienced by the strain-sensitive magnetic particles, and analyzing changes in the strains experienced by said strain-sensitive magnetic particles that may indicate damage or degradation in the structure, and a controller configured for periodic interrogation of the at least one multiferroic sensor.
