<p>Geosynthetic materials are widely used as reinforcement materials, and strain monitoring is becoming increasingly important to ensure the safety of reinforced soil structures. A sensor-enabled piezoelectric geobelt (SPGB) is composed of piezoelectric ceramics, conductive carbon black, and a base material. Owing to the impedance strain and piezoelectric effects, the SPGB can sense its own strain and ambient vibration through impedance and voltage, while providing enhancement. To determine the performance of SPGB at various service temperatures, the strain signal response of SPGB at various service temperatures was investigated experimentally. The results showed that the fracture strength and elongation at break of the SPGB were affected by the coupling of temperature and tensile strain rate. Experimental regression analysis established functional equations to predict the strength and sensing characteristics of the SPGB under different temperature and deformation conditions. Based on the application of SPGB at different ambient temperatures, a linear normalized impedance correction model considering the temperature effect was proposed in this study. The measurement accuracy of SPGB is up to millimeter, with an average error of 3.75%, which can provide temperature compensation for SPGB to accurately respond to strain at different temperatures.</p>
