【摘要】 使用聚四氟乙烯（PTFE）纱作为上层表面纱、镀银锦纶作为下层表面纱以及锦纶单丝和复丝作为间隔丝，根据间隔丝在前后针床集圈所隔针距不同在斯托尔横机上编织3种间隔织物。依据使用材料介电性能不同，研究其垂直接触-分离模式摩擦电性能。间隔层前后针床隔7针进行集圈的间隔织物输出表现优异，对其在频率、压强变化下摩擦电输出进行测试。结果表明：在25 cm~2测试面积下，织物输出特性与频率、压强呈正相关；在2.5 Hz、5.0 kPa测试条件下，织物短路电流为0.19μA，开路电压为32 V；在循环测试10 000次后及水洗5次后，输出有良好稳定性；能量收集方面，手动拍打时其输出可点亮34个LED发光二极管，可用于监测压力、人体运动等，能识别走路、跑步等动作。更多还原

【Abstract】 The article uses PTFE yarn as the upper surface yarn, silver plated nylon as the lower surface yarn,and nylon monofilament and multifilament as the spacer yarn. According to the different spacing between the needles in front and back needle beds, three types of spacer fabrics are knitted on Stoll flat knitting machine. The triboelectric properties of the vertical contact-separation mode are studied due to the different dielectric properties of the materials.The spacer fabric with 7 needles tucking in the front and back of the spacer layer has excellent output performance.The triboelectric output of spacer fabric under frequency and pressure changes is tested and compared. The results show that the output characteristics of the fabric are positively correlated with the frequency and pressure under the tested area of 25 cm~2. Under the condition of 2.5 Hz and 5.0 kPa, the short-circuit current of the fabric is 0.19 μA and the open-circuit voltage is 32 V. And after 10 000 cycles of test and 5 times of washing, the output is almost unchanged, showing good stability. In terms of energy collection, its output can light up 34 LED under the condition of manual tapping. It can also be used to monitor different strength and elbow bending angles. And it can also accurately identify walking, running movements involved.更多还原
