摘要：
A flexible pyramidal piezoelectric structure composed of a PVDF-TrFE piezoelectric film which can generate high output voltage is simulated and fabricated. Compared to the flat, square columnar and trigonal-line micropatterned thin films, the pyramidal structure has stronger variation strain and produces higher piezoelectric signals. When they are subjected to the same mechanical load, the pyramidal structure generates output voltage that is 9 times larger than that of the planar film. The optimized flexible piezoelectric film has broad application in self-powered pressure sensors.
