Inspired by the water strider and other animals can perceive the body vibration by the hair sensors, a bionic fiber sensor is designed that can perceive the external vibration. The preparation of the piezoelectric ceramic fiber embryo body containing platinum core is prepared by the dry pressing molding in module, after high temperature sintering, coated electrode on the surface, after the polarization, the MMPF vibration sensor is fabricated. The cantilever beam structure is fabricated. Two pair of surface electrodes are used as the theoretical models of the sensing electrodes. The fiber is fixed on the substrate to verify the sensing performance of the sensor in which the substrate structure excited by the simple harmonic vibration. The results show that the MMPF can perceive the matrix structure under simple harmonic excitation frequency,amplitude and direction. This bionic fiber vibration sensors which can perceive the amplitude and direction will have a wide range of application prospects.
