“…Each of these methods has its own advantages, but some limitations, such as low signal-to-noise ratio, high computational cost, indirect approach, and limited range, have been reported [14,15]. To overcome these limitations, in situ monitoring exploiting the piezoresistive behavior of conductive networks of carbon nanotubes (CNTs) has been reported [15][16][17]. When a CNT network in the matrix or in the yarns breaks due to microscopic damage, the electrical conductivity of the composite changes.…”
