Abstract

In this study, a novel flexible piezoelectric transducers with high piezoelectric constant (d33) was fabricated by introducing ceramic powder and graphene particles. The optimization of the composition of the compound was investigated by orthogonal design of experiments. The result shows that volume fraction of ceramic/polymer and the mass of graphene particles play an important role in improving piezoelectricity. Microscopic analysis was also employed to analyze the composite film, which showed that the overall microstructure of the proposed composite film. After the composition optimization, screen printing electrode combined with flexible printed circuit were used to realize a convenient and stable transducer packaging. The test results on the cantilever beam reveal that the proposed transducer has an excellent sensing performance in both dynamic strain monitoring and ultrasonic guided wave sensing on curved surface.
