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.

“…Pb(Zr,Ti)O 3 (PZT) and related materials have been widely applied because of their excellent piezoelectric properties. [1][2][3][4] However, the toxicity of lead oxide has called for the development of lead-free piezoelectric materials. Materials based on BaTiO 3 , 5,6) (Bi,Na)TiO 3 , [7][8][9][10] and (K,Na)NbO 3 [11][12][13][14] are considered as suitable candidate replacements for PZTbased materials.…”

Pb(Zr,Ti)O 3 and related materials have been lauded for their piezoelectric properties, but their toxicity has driven the search for alternative materials with the same high performance in electronic devices. Among these, BaTiO 3 -based materials are regarded as excellent substitutes. Using a screen printing method, in this study, we prepare BaTiO 3 thick films on ZrO 2 stabilized with 3 mol % Y 2 O 3 (YSZ) or MgO ceramics with Pt bottom electrodes. BaTiO 3 thick films prepared on YSZ and MgO substrates preferentially oriented along the a-and c-axes, respectively. The remanent polarization P r of the MgO-based films was higher than that of the YSZ-based films (10.8 µC/cm 2 vs 6.5 µC/cm 2 ) and comparable to that of BaTiO 3 bulk ceramics. Thermal expansion measurements of BaTiO 3 , YSZ, and MgO ceramics suggested that compressive stress was exerted on the BaTiO 3 thick films, causing them to orient along the c-axis. (Ba 0.92 Ca 0.08 )(Ti 0.975 Zr 0.025 )O 3 thick films were also prepared on the YSZ and MgO substrates and showed similar preference for the c-axis on MgO. However, the remanent polarization of (Ba 0.92 Ca 0.08 )(Ti 0.975 Zr 0.025 )O 3 thick films prepared on MgO was greater than that of bulk ceramics (14.9 µC/cm 2 vs 11.0 µC/cm 2 ).

“…Thus, as an alternative energy source, many energy harvesters have been actively researched. Energy harvesters provide a small amount of energy from, for example, solar, 1) thermal, 2) vibration, [3][4][5] and radio wave sources. Among various energy harvesters, in this study, we focus on the RF energy harvester (RF-EH) because it can be integrated with the other functional circuits, and the integration can reduce external components, volume, and cost.…”

In this study, we present an RF energy harvesting power management unit (PMU) for battery-less wireless sensor devices (WSDs). The proposed PMU realizes a duty-cycled operation that is divided into the energy charging time and discharging time. The proposed PMU detects two types of timing, thus, the appropriate timing for the activation can be recognized. The activation of WSDs at the proper timing leads to energy efficient operation and stable wireless communication. The proposed PMU includes a hysteresis comparator (H-CMP) and an RF signal detector (RF-SD) to detect the timings. The proposed RF-SD can operate without the degradation of charge efficiency by reusing the RF energy harvester (RF-EH) and H-CMP. The PMU fabricated in a 180 nm Si CMOS demonstrated the charge operation using the RF signal at 915 MHz and the two types of timing detection with less than 124 nW in the charge phase. Furthermore, in the active phase, the PMU generates a 0.5 V regulated power supply from the charged energy.
