Smart materials for ultrasonic piezoelectric composite transducer: A short review

At every step of development, advanced composite combinations are found, resulting in a material revolution. Smart materials, with their many classifications and characteristics, play an important part in today's research. The vast majority of dielectric, electro-magnetic, fatigue, and electric attributes were completely studied. These factors influence the working performance of piezoelectric composite materials. For various stiffness ratio the breakage point of the material changes does affects the fatigue cycle is explained. For ultrasonic transducer applications, we may design the structure to produce materials with better electromechanical coupling and lower acoustic impedance than traditional piezoelectric ceramics. The requirement for composites in piezoelectric transducers explains the high performance and high-end applications. The interaction of the main factors was displayed under various situations, majority of changes happens in the mechanical and chemical property changes and that can be recovered by treating the material and the results were explained.
