摘要

模仿蜘蛛毛发感受器的结构和功能，设计制备了表面对称电极含金属芯聚偏二氟乙烯（PVDF）纤维（SMPF）的简谐振动传感器。用挤压拉伸的方法制备纤维胚体，将纵向表面涂镀形状完全对称的导电胶作为外部电极，经过极化后，制备成SMPF简谐振动传感器。基于压电方程和振动理论，建立了悬臂梁结构的SMPF简谐振动传感器的理论模型，分析了传感信号与简谐振动角度和幅值的关系。将SMPF简谐振动传感器固定在基体上，搭建了实验系统，测试了SMPF简谐振动传感器对简谐振动的响应，验证了理论模型。结果表明，SMPF简谐振动传感器能够准确感知简谐振动的频率，传感信号和简谐振动的幅值呈线性关系，和振动方向成"8"字形关系，共振频率为15.6 Hz，灵敏度为0.019 pC/mm。该SMPF传感器能够测量简谐振动频率、幅值或方向，具有广泛的工程应用前景。

Abstract

Inspired by the structure and function of spider hair receptors

a simple harmonic vibration sensor with Symmetrical Electrode Metal-core Piezoelectric Fiber (SMPF) was designed and fabricated. The fiber body was prepared by extrusion-stretch method

and the symmetrical conductive adhesive was used as the external electrode in the longitudinal surface. After polarization

the simple harmonic vibration sensor with the SMPF was prepared. Based on the piezoelectric equation and the vibration theory

the theoretical model of harmonic vibration sensor with the SMPF based on a cantilever beam structure was established

and the relationship between the sensor signal and the angle and amplitude of simple harmonic vibration was analyzed. The SMPF was fixed on a substrate

and an experimental system was built. The response of the sensor to simple harmonic vibration was tested and the theoretical model was verified. The results show that the sensor with the SMPF can accurately sense the frequency of harmonic vibration

the sensor signal is linear related to the amplitude of simple harmonic vibration

and has an "8" shape relationship with the direction. Moreover

the resonance frequency of SMPF is 15.6 Hz

and the sensitivity is 0.019 pC/mm. In conclusion

the sensor with the SMPF can measure the frequency

amplitude or the direction of simple harmonic vibration and has prospect for engineering applications.
