Much recent work has been devoted to utilizing changes in either the inherent or imparted electrical conductivity of self-sensing materials as an indicator of damage, deformation or strain, pressure, or general condition (e.g. moisture content, UV exposure, pH, etc). The scope of self-sensing materi...
