Special Issue Information

Dear Colleagues,

This Special Issue on "Advanced Design and Synthesis in Piezoelectric Smart Materials" aims to explore the latest advancements in the field of piezoelectric materials, with a focus on innovative design strategies and synthesis techniques. Piezoelectric materials, which convert mechanical stress into electrical energy and vice versa, have garnered significant attention due to their wide range of applications in sensors, actuators, and energy harvesting devices. This Special Issue seeks to highlight cutting-edge research that pushes the boundaries of piezoelectric material development, including the exploration of new material compositions, advanced synthesis methods, and enhanced performance optimization. We invite contributions that delve into the fundamental principles, experimental approaches, and practical applications of piezoelectric smart materials. Full papers, communications, and reviews that address these themes are warmly welcomed. Together, we aim to provide a comprehensive overview of the current state and future directions of piezoelectric smart materials research.

With the rapid development of urban rail transit, the floating slab vibration isolation system has become widely used in the field due to its effective vibration reduction and isolation capabilities. Traditional floating slab vibration-isolation systems mainly focus on blocking vibration transmission, neglecting energy harvesting. This paper proposes a magnetic-coupled double-wing negative stiffness energy harvester for floating slabs. A single-wing piezoelectric beam model and a finite element model of the magnetic-coupled module are established. The modal and output characteristics of the single-wing piezoelectric beam are analyzed. Furthermore, the force characteristics of the magnetically coupled negative stiffness module are analyzed. The results show that the contribution of its width to the modal frequency gradually decreases with an increase in the length of the single-wing piezoelectric beam. The thickness significantly influences the characteristic frequency, and the load is exponentially related to the output power. At the optimal load and characteristic frequency of the single-wing piezoelectric beam, the output characteristics decrease with an increase in the width. The peak value of the magnetic-coupled negative stiffness gradually decreases with an increase in the magnetic gap. The increase in remanent magnetic strength indicates that the initial state of the magnetic ring is more easily affected by external conditions. The change in axial magnetic force becomes significant with increased displacement. This research enriches the theoretical systems of piezoelectric energy harvesting technology and magnetic-coupled negative stiffness mechanism while providing important theoretical support for subsequent experimental research, optimal design, and practical applications.
