棉织物基ZnO/BaTiO3/PVDF压电传感器及其性能
Cotton fabric-based ZnO/BaTiO3/PVDF piezoelectric sensor and its performances
摘要
Abstract
To address the promble of insufficient of flexibility and sensitivity of existing piezoelec-tric sensors,a fabric-based flexible piezoelectric sensor with both excellent piezoelectric sensing performance and wearable characteristics was developed by combining the high piezoelectric strain constant of inorganic piezoelectric materials,the good flexibility of organic piezoelectric materials and the wearable property of fabric substrates.ZnO,BaTiO3 and ZnO/BaTiO3 piezoelectric pow-ders were synthesized by hydrothermal method and molten salt method,respectively.The cotton fabric-based ZnO/PVDF,BaTiO3/PVDF and ZnO/BaTiO3/PVDF piezoelectric sensors were fabrica-ted by tape casting.The effects of the preparation process on the microstructure and morphology were investigated by XRD,SEM,TEM,FT-IR and XPS.The piezoelectric sensing performance was evaluated by using a shaker and a digital source meter to reveal the piezoelectric sensing mecha-nism.The results show that the ZnO/BaTiO3 composite piezoelectric material has both high piezoe-lectric strain constant and low resistance characteristics.The peak voltage and sensitivity of the cotton fabric-based ZnO/BaTiO3/PVDF piezoelectric sensor is 2.55 V and 1.02 V/kPa,respectively.The research results can provide ideas for the design and development of high-sensitivity flexible fabric-based piezoelectric sensors.关键词
