“…The echo is detected and displayed o fluorescent screen, so that doctors can understand the internal condition of the hum body. Piezoelectric gyroscopes [62][63][64][65] fabricated from piezoelectric ceramics, illustrated in Figure 4, are attached to the rudder of spacecraft and artificial satellites, and thereby guarantee a stable fixed route. Traditional mechanical gyroscopes, with short life, poor accuracy, and low sensitivity, cannot meet the requirements of modern spacecraft and satellite system.…”

Piezoelectric ceramics are inexpensive functional materials which are widely used in sonar detection, home appliances, meteorological detection, telemetry and environmental protection and other applications. Sensors fabricated from these materials are compact and have fast response characteristics. Their underlying functional methodology is based on the direct piezoelectric effect whereby very small mechanical vibration signals are converted into electrical signals. Piezoelectric resonators are based on the reverse piezoelectric effect and they are widely used for the control of precision instruments and precision machinery, microelectronic components, bioengineering devices and other in applications requiring components to provide precision control of the relevant functional mechanism. In this paper, the structural evolution and design mechanism of sandwich resonators based on piezoelectric materials are reviewed, and the advantages and disadvantages of different structures are compared and analyzed. The goal is to provide a comprehensive reference for the selection, application and promotion of piezoelectric resonators and for future structural innovation and mechanism research relevant to sandwich resonators.
