Many instruments and sensors have been invented to measure pressure, with different advantages and disadvantages. Many factors like pressure range, accuracy, sensitivity, reproducibility, dynamic response, and cost are involved in developing a pressure measuring device. This research paper describes the study of variation in the dielectric constant of lead iron tungstate relaxor specimens with pressure and temperature. In this study, the investigator optimized the specimen's preparation method by changing calcination temperature, adding excess lead oxide, using conventional mixed oxides and columbite routes to improve the specimen's pressure-sensing properties. This study adds another pressure-sensing application of relaxor materials among many other applications.

已经发明了许多仪器和传感器来测量压力，具有不同的优点和缺点。压力测量设备的开发涉及许多因素，如压力范围、精度、灵敏度、再现性、动态响应和成本。本研究论文描述了钨酸铅弛豫样品介电常数随压力和温度变化的研究。在本研究中，研究者通过改变煅烧温度、添加过量氧化铅、使用常规混合氧化物和铌铁矿路线来优化试样的制备方法，以提高试样的压力传感性能。这项研究在许多其他应用中增加了弛豫材料的另一种压力传感应用。
