多孔纳米纤维基自供电传感器的构建及性能研究
Construction and performance study of hierarchical porous nanofiber-based self-powered sensor
摘要
Abstract
In response to the current lack of electrical output performance in triboelectric nanogenerators(TENG)and the limitations of methods to increase the surface roughness of polyvinylidene fluoride(PVDF)-based TENGs,a combination of multiple roughening technique was adopted.Electrospinning and template sacrificial method were used to prepare PVDF porous nanofiber,and concentration of the template sacrificial component,polyvinylpyrrolidone(PVP),was adjusted to achieve effective control of the porous structure,the surface roughness of the fibers was significantly increased.The optimized porous PVDF nanofiber membrane was encapsulated to fabricate a single-electrode TENG,and its self-powered performance was tested.The porous PVDF nanofiber-TENG(PPNG)was applied to human motion monitoring.The results showed when the mass fraction of PVP was 28%,the PPNG exhibited excellent electrical output performance,an output voltage was 45 V,short-circuit current was 0.58 μA,charge density was 17 μC/m2 and power density was 0.39 W/m2,compared with TENG prepared from a simple PVDF electrospinning membrane,electrical output to the PPNG was increased 114.3%.PPNG could effectively detect physiological movements such as walking,arm folding and arm contact,and it had better application potential in the fields of motion monitoring and biomechanical energy harvesting.关键词
