Laboratory preparation and tensile signal response of sensor-enabled piezoelectric geobelt

In this study, a sensor-enabled piezoelectric geobelt (SPGB) was developed and its mechanical properties and signal output mode were analysed. It is found that the output voltage signal of SPGB increases with the increase of strain rate. Furthermore, the normalised impedance of SPGB samples at different strain rates has a linear relationship with their strain rate. This study shows that the self-sensing function of SPGB can monitor its deformation signal and quantify its deformation behaviour. Thus, this function can provide an early warning and has a reference significance for further engineering applications of SPGB.
