Abstract: The present invention relates to a carbon nanotube-enhanced cementitious composite for self-powered structural health monitoring. The composite comprises a cementitious matrix incorporating carbon nanotubes distributed within the matrix to form an electrically conductive network. The conductive network exhibits piezoresistive behavior, wherein mechanical strain, deformation, vibration, loading, and crack development produce measurable changes in electrical resistance, impedance, or conductivity. A plurality of electrodes is provided for acquiring electrical responses from selected regions of the composite. An energy-harvesting arrangement is coupled to the composite or an associated structural component to convert mechanical deformation, vibration, or cyclic loading into electrical energy. The harvested energy is conditioned and stored in an energy-storage unit for powering sensing, signal-processing, control, and communication circuitry. A controller analyzes electrical responses from the composite to identify structural abnormalities and determine changes in structural condition. A wireless communication module may transmit the processed structural health information to a remote monitoring platform. The invention thereby integrates structural material, self-sensing functionality, energy harvesting, and low-power monitoring into a unified system, enabling continuous or periodic monitoring of cement-based infrastructure with reduced dependence on external power sources and reduced requirements for conventional discrete sensing systems.
