一种仿生感觉毛气流传感器
A Bionic Sensory Hair for Airflow Sensor
摘要
Abstract
Imitation of insect hair senses the structure of hair,a symmetric-electrodes metal core PVDF fiber (SMPF)airflow sensor was designed and fabricated. A SMPF embryo was successfully prepared using self-made drawn fiber equipment. After coated symmetrical electrodes on the surface,high temperature polarization,electrode packaging and other processes,a SMPF air flow sensor was successful fabricated. Based on the first type of piezoe-lectric equation and fluid mechanics theory,the SMPF airflow sensor model of cantilever structure is established. The SMPF of the cantilever structure is placed in the air flow field and the impact airflow test is carried out.The ex-perimental results show that the output signal of SMPF air flow sensor has a nonlinear relationship with the fiber length,which is in square relationship with the velocity of air flow and the"8"shape relationship with the direction of airflow. The experimental results verify the theoretical model. It is shown that the SMPF sensor can sense the speed and direction of the airflow and has a wide range of engineering application prospects.关键词
