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.…”

Electro-elastic properties of a piezoelectric Te2O(PO4)2crystal

“…The YBa 3 (PO 4 ) 3 and YbBa 3 (PO 4 ) 3 crystals exhibit a large and pure face-shear vibration mode, and are candidates for acoustic wave sensing application. 13 An excellent piezoelectric crystal usually has a high piezoelectric constant and electromechanical coupling coefficient and good piezoelectric temperature stability. 14,15 However, due to the very small polarizability anisotropy of the highly symmetric [PO 4 ] tetrahedral group, 16 phosphate piezoelectric crystals typically display small piezoelectric constants, which greatly affects the application of such crystals.…”

Analysis of SAW Temperature Properties in KTiOPO4 Single Crystal

“…Therefore, the BG wave cannot be used for microfluidic excitation, and it makes them suitable for measuring a liquid viscosity. The surface acoustic wave is widely used in the temperature, pressure sensors, and microfluidic applications [27][28][29][30][31][32][33]. Generally, the SAW has three components of mechanical displacement on the crystal surface: the first one is parallel to the direction of wave propagation, the second one is perpendicular to the direction of propagation, and the third one is normal to the substrate surface.…”
