“…Piezoelectric ceramic smart aggregate, due to its advantages of low cost (Du et al, 2016a(Du et al, , 2016bZeng et al, 2015), strong piezoelectric effect (Zeng et al, 2018;Song et al, 2017), fast response with wide band and high frequency (Hu et al, 2014;Yang et al, 2008;Wang et al, 2014), the ability to be used as actuators and sensors (Wang et al, 2016;Shao et al, 2016), the capacity to harvest energy and so on, is widely used in structural health monitoring and damage detection. The piezoceramicbased active-sensing method has been accepted in the field of structural health monitoring and applied to the health diagnosis of structural damage in blasting engineering (Song et al, 2004;Krishna and Rajanna, 2004).…”
