Piezoelectric materials lie at the heart of electromechanical devices. Applications include actuators, ultrasonic imaging, high intensity focused ultrasound, underwater ultrasound, nondestructive evaluation transducer, pressure sensors, and accelerometers, to name a few. In this work, the advantages and disadvantages of relaxor-PbTiO(3)-based single crystals are discussed, based on the requirements (figure of merit) of various applications, with emphasis on recent developments of the shear properties of single crystals as a function of temperature and applied fields.
压电材料是机电设备的核心。其应用包括致动器、超声成像、高强度聚焦超声、水下超声、无损检测换能器、压力传感器和加速度计等等。在这项工作中,基于各种应用的要求(品质因数),讨论了弛豫-钛酸铅(PbTiO₃)基单晶的优缺点,重点是单晶剪切特性随温度和外加场的最新进展。
