The durability of piezoresistive sensor materials is a core prerequisite for their implementation in structural health monitoring systems. In this work, three were subjected to extensive cyclic tensile loadings, and behaviour was analysed before, after, during testing. To end, aluminium specimens coated with different industry-grade lacquers, then applied onto each specimen. Sensors made from carbon black displayed excellent linearity even after loading cycles (R2>0.88). A decline all sensors based on allotropes discovered, whereas the polymer-based improved. Furthermore, adhesion substrate great importance. Good ensures strains underlying structure are correctly transmitted into materials. Based contact angle measurements liquids work determined. findings verified by tape tests.
