Research in polymer-based functional powder preparation and additive manufacturing has led to the innovative development of a continuous Materials Science and scalable technology for producing polymer-based spherical powders by integrating solid-phase shear milling with plasma processing. This advanced approach enables precise control over powder morphology, surface activity, and flow behavior, making it highly suitable for high-performance three-dimensional printing applications. Building on this foundation, extensive efforts have been devoted to the design and fabrication of high-efficiency piezoelectric composite materials that exhibit enhanced electromechanical conversion performance, mechanical robustness, and long-term stability. Through systematic theoretical analysis combined with computational simulation, the underlying structural and interfacial mechanisms governing piezoelectric output have been clarified, particularly the influence of device architecture, layer configuration, and stress distribution. These insights have supported the successful development of multi-scale and multi-layered three-dimensional piezoelectric devices with unique stress-responsive behaviors and stable output under complex loading conditions. The research integrates materials synthesis, processing technology, device engineering, and performance optimization, contributing to advances in functional polymer composites, intelligent sensing systems, and energy harvesting technologies. This work demonstrates strong interdisciplinary innovation and provides a solid foundation for the scalable application of polymer-based piezoelectric devices in advanced manufacturing and smart materials systems.
