Two types of porous lead zirconate titanate (PZT) with different pore morphologies and porosities were fabricated by freeze-casting and burnt-out polymer sphere techniques, respectively. The effects of porosity and pore morphology on the sensing application of porous PZT ceramics were investigated. The result shows that the decreasing rate for piezoelectric charge coefficient d33 is slower than that of relative permittivity εr for porous PZT ceramics, leading to a better piezoelectric performance for the porous PZT rather than that of the dense ceramic. Moreover, d33 of porous ceramics with random spherical pores decreases, compared to that of the porous ceramics with aligned pores. Therefore, the porous PZT ceramic with aligned pores has a higher output voltage. The maximum output voltage reaches up to 84 V, which is generated by the 55.9% porous PZT with aligned lamellar pores under 8 N external force. This work is beneficial for understanding the effect of the pore characteristic on the sensing properties of piezoelectric ceramics and provides a new idea for the preparation of sensors with high piezoelectric coefficient.

采用冷冻浇注和添加造孔剂2种方法制备了不同孔形貌和孔隙率的多孔PZT压电陶瓷,系统研究了不同孔形貌和孔隙率对多孔PZT陶瓷的传感性能影响。结果表明:在多孔陶瓷中,压电电荷系数d33随孔隙率增加的下降速度比介电常数εr缓慢,使得多孔陶瓷压电传感性能较致密陶瓷得到大幅提高。此外,添加造孔剂法制备的随机多孔陶瓷d33与冷冻浇注制备得到的取向多孔陶瓷相比下降更显著,因此取向多孔陶瓷具有更高的传感输出电压,在8 N外力作用下,孔隙率为55.9%(体积分数)的取向多孔陶瓷达到了最高84 V的输出电压。本研究有助于了解多孔特性对压电陶瓷的传感性能影响,并为制备具有高压电系数的传感器件提供新的思路。

采用冷冻浇注和添加造孔剂2种方法制备了不同孔形貌和孔隙率的多孔PZT压电陶瓷,系统研究了不同孔形貌和孔隙率对多孔PZT陶瓷的传感性能影响。结果表明:在多孔陶瓷中,压电电荷系数d33随孔隙率增加的下降速度比介电常数εr缓慢,使得多孔陶瓷压电传感性能较致密陶瓷得到大幅提高。此外,添加造孔剂法制备的随机多孔陶瓷d33与冷冻浇注制备得到的取向多孔陶瓷相比下降更显著,因此取向多孔陶瓷具有更高的传感输出电压,在8 N外力作用下,孔隙率为55.9%(体积分数)的取向多孔陶瓷达到了最高84 V的输出电压。本研究有助于了解多孔特性对压电陶瓷的传感性能影响,并为制备具有高压电系数的传感器件提供新的思路。

Two types of porous lead zirconate titanate (PZT) with different pore morphologies and porosities were fabricated by freeze-casting and burnt-out polymer sphere techniques, respectively. The effects of porosity and pore morphology on the sensing application of porous PZT ceramics were investigated. The result shows that the decreasing rate for piezoelectric charge coefficient d33 is slower than that of relative permittivity εr for porous PZT ceramics, leading to a better piezoelectric performance for the porous PZT rather than that of the dense ceramic. Moreover, d33 of porous ceramics with random spherical pores decreases, compared to that of the porous ceramics with aligned pores. Therefore, the porous PZT ceramic with aligned pores has a higher output voltage. The maximum output voltage reaches up to 84 V, which is generated by the 55.9% porous PZT with aligned lamellar pores under 8 N external force. This work is beneficial for understanding the effect of the pore characteristic on the sensing properties of piezoelectric ceramics and provides a new idea for the preparation of sensors with high piezoelectric coefficient.
