Additive Manufacturing of Piezoelectric Materials

Abstract

Additive manufacturing technology has attracted unprecedented attention in industry because it provides infinite possibilities for rapid prototyping and enormous potential and opportunities for the production of electronic devices of various complex shapes. This paper focuses on the progress of additive manufacturing of piezoelectric materials in recent years, summarizing the advantages of additive manufacturing technology and its technical impact on the production of piezoelectric materials. It identifies the likely future research development direction of additive manufacturing technology, as well as the limitations of the current additive manufacturing technology in the context of piezoelectric materials. First, the various processes involved in additive manufacturing of piezoelectric devices and the impact of various processes on device performance are systematically summarized. Then, the development of additive manufacturing technology and slurry preparation of piezoelectric ceramic materials, piezoelectric polymer materials, and piezoelectric composites are introduced. Finally, the technical difficulties and potential research directions associated with additive manufacturing of piezoelectric materials are discussed. With the continuous development of additive manufacturing technology and piezoelectric materials, additive manufacturing of piezoelectric devices with excellent performance, high energy storage density, and high electromechanical conversion efficiency will be applied in a wider range of fields in the future.
