Abstract

The invention provides a stacked piezoelectric transducer suitable for road piezoelectric power generation and a manufacturing method. The manufacturing method sequentially manufactures a circular ceramic substrate, a rounded corner ceramic substrate, and a rounded corner piezoelectric ceramic single piece. , making stacked piezoelectric ceramics, making stacked piezoelectric transducers. The present invention optimizes the structure and shape of the piezoelectric ceramic sheet from the manufacturing process to ensure the symmetry and uniformity of the electrode coating on both sides, and the fillet technology can make the electrode layer and the ceramic sheet have a good fit to avoid porcelain leakage phenomenon, to achieve good durability and long service life; at the same time, the setting of metal plates on both sides can increase the structural integrity and strength. The stacked piezoelectric transducer prepared by the invention is suitable for road piezoelectric power generation and has the advantages of high force-to-electricity conversion efficiency, high rigidity, regular structure, and the like.

Description

technical field [0001] The invention belongs to the field of road engineering and relates to road piezoelectric power generation, in particular to a stacked piezoelectric transducer suitable for road piezoelectric power generation and a manufacturing method. Background technique [0002] my country's road network is becoming more and more developed, and roads bear more and more vehicle loads. The constant impact and vibration of the vehicle load will generate a steady stream of mechanical energy. If this mechanical energy is effectively collected and converted into electrical energy, it will be used as another clean energy besides solar energy, wind energy, and nuclear energy. At this stage, my country is actively developing a clean production capacity model for new intelligent piezoelectric power generation surfaces, which is of great practical significance to the practice of green transportation, the promotion of green road construction, and the completion of the "13th Fi...
