This work reports for the first time capacitance-based nondestructive evaluation (NDE) of a monolithic metal, namely steel. This means that the structural material is self-sensing, without the need

Self-sensing concrete: from resistance-based sensing to capacitance-based sensing

ABSTRACT Self-sensing uses the cement-based material without sensor incorporation to sense itself. This paper reviews self-sensing cement-based materials, with coverage of the well-studied
