However, there are also some limitations to circular tube piezoelectric ceramic sheets. Първо, its mechanical strength and fatigue resistance are relatively low, and it is easily damaged by external impact and cyclic stress. Второ място, its dielectric constant will vary with temperature and frequency, affecting the stability of its performance. Освен това, the manufacturing cost of circular tube piezoelectric ceramic sheets is relatively high, and professional manufacturing equipment and process flow are required.
To overcome these limitations, researchers are constantly exploring new types of piezoelectric ceramic materials and manufacturing processes for circular tubes. Например, advanced ceramic powder preparation techniques, nanocomposites, gradient structured materials, and other methods are used to improve the mechanical strength and stability of circular tube piezoelectric ceramic sheets. В същото време, by optimizing manufacturing processes, reducing manufacturing costs, and improving production efficiency, the cost of circular tube piezoelectric ceramic sheets can be reduced and their application scope can be expanded.
