Piezoelectric ceramics are relatively common materials that can convert mechanical energy and electrical energy into each other. They are widely used in our life in electroacoustic devices, communication, navigation, precision measurement and ultrasonic energy conversion. Its texture is hard and brittle, its processability is not very good, and its use is limited. If piezoelectric ceramics are made into flexible piezoelectric composites by compounding with flexible matrices to improve mechanical properties, they can be applied to wearable and flexible devices. This paper briefly introduces the basic principle of the piezoelectric effect, introduces the preparation methods of three typical flexible piezoelectric composites and their dielectric, piezoelectric and mechanical properties, introduces the recent research work and the latest scientific research achievements of relevant teams, summarizes the research progress of flexible piezoelectric materials, and provides ideas for finding flexible piezoelectric composites that have good dielectric, piezoelectric and mechanical properties.

“…Generally speaking, ceramic materials are brittle and have low fracture toughness, which limits their applications in severe thermomechanical environments. Piezoelectric composites including reinforced piezoelectric ceramics have been investigated to improve the piezoelectric performance and mechanical properties [3][4][5][6][7][8][9][10][11][12][13][14][15]. Most investigations have been focused on piezoelectric composites with at least one-phase that is not self-connected in threedimensions (3D).…”

This paper presents a poro-thermo-piezoelectricity model to investigate infiltration processing of an interpenetrating phase piezoelectric ceramic composite and the thermomechanical responses of the piezoelectric matrix during infiltration by a molten reinforcement phase. Governing equations for fluid-infiltrated porous piezoelectric materials are first formulated based on the theories of thermoporoelasticity and piezoelectricity. Similarity solutions of temperature distribution, infiltration kinetics, pore melt pressure, melt content variation, and stress/strain fields are obtained for infiltration of a porous piezoelectric matrix under one-dimensional strain and flow conditions. Numerical results for infiltration of a long porous PZT bar by a liquid polymer indicate that the infiltration kinetics and pore fluid pressure are similar to those under isothermal processing conditions. The melt content variation in the PZT, however, is dramatically affected by the difference between the inlet melt temperature and initial matrix temperature. A relatively lower inlet melt temperature results in positive melt content variation implying that more melt in the pores of the piezoelectric matrix is available to compensate solidification shrinkage of the molten reinforcement phase thereby reducing the solidification induced microdefects in the composite.The stresses in the piezoelectric matrix during the infiltration are compressive with the magnitudes on the order of the applied inlet melt pressure. The axial strain may become tensile near the inlet when the inlet melt temperature is above the initial matrix temperature.

Piezocomposites with both flexibility and electromechanical conversion characteristics have been widely applied in various fields, including sensors, energy harvesting, catalysis, and biomedical treatment. In the composition of piezocomposites or their preparation process, a category of materials is commonly employed that do not possess piezoelectric properties themselves but play a crucial role in performance enhancement. In this review, the concept of auxiliary phase is first proposed to define these materials, aiming to provide a new perspective for designing high‐performance piezocomposites. Three different categories of modulation forms of auxiliary phase in piezocomposites are systematically summarized, including the modification of piezo‐matrix, the modification of piezo‐fillers, and the construction of special structures. Each category emphasizes the role of the auxiliary phase and systematically discusses the latest advancements and the physical mechanisms of the auxiliary phase enhanced flexible piezocomposites. Finally, a summary and future outlook of piezocomposites based on the auxiliary phase are provided.
