Investigations on the Sensitivity of Airflow Using Partially Coated Metal Core Piezoelectric Fiber
摘要
Abstract
Metal core piezoelectric fiber can simulate insects’hair flow sensors,and measure the airflow changes of the surrounding environment. In this paper,we coated part of the longitudinal surface of the metal core piezoelectric fiber with electrode,and prepared partial coated metal core piezoelectric fibers(PMPF). Based on the average charge method,the cantilever PMPF quasi-static airflow sensor model was established,the relationship between the two electrodes’charge value on PMPF and the surface electrode distribution angle and the length of fiber were ana⁃lyzed. The experimental platform of cantilever PMPF airflow sensor was established,and the response of PMPF when impact airflow acted on was tested whose results verified the theoretical model. The results show that the out⁃put signal of the PMPF has a index relation with the air flow velocity,and a"8"glyph relation with the air flow direc⁃tion. PMPF has the properties of sensing the airflow velocity and direction.关键词
