“…These materials are made of crystals or ceramics that have a specific crystal structure, such as quartz or barium titanate. The piezoelectric effect is due to the alignment of the crystal structure, which generates an electrical charge when the material is deformed (Behera, 2022;Sekhar et al, 2022).…”

4D printing is a cutting-edge technology that allows for the creation of dynamic, self-assembling structures by utilizing cutting edge, newly introduced smart materials. It builds upon traditional 3D printing by adding the dimension of time, allowing printed objects to change shape or behavior over time. This is achieved through the use of smart materials, such as shape memory alloys or polymers, which respond to external stimuli such as heat or moisture. These materials are engineered to have specific properties that can be triggered by specific conditions such as temperature, humidity, light, or other physical forces. 4D printing enables the creation of structures that can adapt to their environment and perform specific functions, such as objects that change shape in response to temperature changes, or structures that can self-assemble in response to a specific trigger. Overall, 4D printing is an exciting and rapidly advancing technology that has the potential to revolutionize the way we design and create structures. The ability to create structures that can change shape or behavior over time opens up new possibilities for a wide range of applications. As the technology continues to evolve, we can expect to see more innovative uses of 4D printing in a wide range of scientific fields such as architecture, aerospace, and biomedical engineering demanding the creation of highly complex and dynamic structures that can adapt to changing environments.

“…In natural water bodies, tides, waves, and turbulence caused by aquatic animal movements can be used as sources of mechanical energy for piezoelectric catalysts, thus allowing organic pollutants to be oxidized without consuming external reagents or an applied power source. Early in the last decade, attempts to treat water pollutants with piezoelectric catalysis began with the use of microdendritic crystalline powder of BaTiO 3 to degrade acidic orange 7 (AO7) dye in water by Li et al [70] Until now, great progress has been made in the field of piezoelectric catalytic degradation in terms of both material and microstructural innovations [4,32c,71] . Nevertheless, these efficient catalysts are generally used by dispersing their powders in a contaminant solution.…”

Despite piezoelectric materials have a long history of application, piezoelectric catalysis has continued to be a hot topic in recent years. Flexible piezoelectric materials have just emerged in recent years due to their versatility and designability. In this paper, we review the recent advances in flexible piezoelectric materials for catalysis, discuss the fundamentals of the catalytic properties of composite materials, and detail the typical structures of these materials. We pay special attention to the types of filler in flexible piezoelectric composites, their role and the interaction between the particles and the flexible substrate. Notable examples of flexible piezoelectric materials for organic pollutants degradation, enhanced piezo‐photocatalysis and antibacterial are also presented. Finally, we present key issues and future prospects for the development of flexible piezoelectric catalysts.

“…10 Some less common types of piezoelectric materials are also explained subsequently. Apart from the most common natural piezoelectric crystals (such as Rochelle salt (potassium sodium tartrate), cane sugar, quartz, tourmaline, and topaz 11,12 ), lithium niobate (LiNbO 3 ), lead magnesium niobate-lead titanate (PMN-PT), and lead zinc niobate-lead titanate (PZN-PT) are known as the piezoelectric single crystals. 13 Piezoceramics are polycrystalline materials consisting of abundant single crystals with similar chemical composition and different orientations.…”
