Beam-focused SH wave transducer based on YSr3(PO4)3 piezoelectric crystal for high temperature structural health monitoring

Shear Horizontal Guided Wave Sensors Based on CTGS Piezoelectric Crystal for High‐Temperature Structural Health Monitoring

“…Taking advantage of the physical anisotropy of CTGS single crystal, the optimum crystal cut YXl/15° was obtained by numerical calculation, which exhibited minimum piezoelectric crosstalk and the largest effective piezoelectric coefficient d 25 ' , being on the order of 14.8 pC N −1 (Figure 1b), higher than the recently reported YSr 3 (PO 4 ) 3 piezoelectric crystal ( d 25 = 9.7 pC N −1 ). [ 37 ] Equation shows the numerical calculation. Figure S2a (Supporting Information) is a diagram of the maximum piezoelectric coefficient cut.…”

The optimal high-temperature piezoelectric cuts of α-BiB3O6 crystals and their fatigue behaviors at high-temperature and low-pressure

“…To date, researchers have paid a lot of attentions to search high-temperature piezoelectric crystal materials with excellent piezoelectric performance and good temperature stability. 12–34 Among the reported piezoelectric materials, including ferroelectric materials and non-ferroelectric piezoelectric crystals, crystal quartz, LiNbO 3 (LN), GaPO 4 and ReCa 4 O(BO 3 ) 3 (Re: rare-earth elements) crystals etc. have been extensively investigated.…”
