“…The results confirmed that the detection performance of 0-3 type piezoelectric composites could satisfy most detection conditions. Zhang et al [9] embedded polyvinylidene fluoride film into a glass-fiberreinforced polymer (GFRP) and successfully detected the mechanical behavior and damage evolution of GFRP in a bending test through piezoelectric output signals. Their results confirmed the potential value of piezoelectric composite materials and piezoelectric polymers in structural health monitoring (SHM).…”

Strengthening and repairing infrastructure with fiber‐reinforced polymers while achieving low‐cost, real‐time monitoring of cracks in engineering structures is highly challenging. Here, a piezoelectric glass‐fiber‐reinforced polymer (piezo‐GFRP) sensor was used to monitor the mechanical behavior of cement beams with cracks under cyclic bending. The output voltage and frequency of the sensor were shown to be effective feedback signals for determining the mechanical behavior. The thin piezo‐GFRP sensor showed sufficient piezoelectric sensitivity to monitor the slight variations in the mechanical behavior of the cement beams during the early stages of cracking. This result indicates that such sensors have the potential for the multi‐functional structural health monitoring of engineering structures.This article is protected by copyright.
