摘要
为改善织物基柔性压力传感器的灵敏度、响应性和稳定性,通过机织结构设计将微结构引入棉织物中,织造了具有圆顶形微表面结构的变化蜂巢组织织物。以变化蜂巢织物、炭黑(CB)和聚乙烯醇(PVA)为原料,采用浸烘法制备了不同的传感织物。测试了炭黑质量分数与传感器电阻的关系,并对制备的传感器结构形貌和力学传感性能进行表征,探讨其在人体运动监测中的应用。结果表明:在炭黑质量分数为5%时,传感器电阻降至20 kΩ/cm,制备的传感器具有较高的灵敏度,较小的迟滞性,在不同压力和压缩速率条件下均能保持良好的稳定性、重复性及耐用性。认为:制备的传感器可以应用于人体运动监测,包括手指按压、指关节、手腕和肘关节弯曲运动等。
In order to improve the sensitivity,responsiveness and stability of flexible pressure sensor based on fabric,a variable honeycomb weave fabric with a dome-shaped micro-surface structure was woven by introducing micro-structures in the woven structure design into cotton fabric.Variable honeycomb fabric,carbon black(CB)and polyvinyl alcohol(PVA)were used as raw materials,different sensor fabrics were prepared by immersion method.The relationship between the mass fraction of carbon black and the sensor resistance was tested,the structural morphology and mechanical sensing performance of the prepared sensor were characterized to explore its application in human motion monitoring.The results showed that the prepared sensor had high sensitivity and small hysteresis when the mass fraction of carbon black was 5%and the sensor resistance was decreased to 20 kΩ/cm.Under different pressures and compression rates,the sensor could maintain better stability,repeatability and durability.It is considered that the prepared sensor can be applied to human motion monitoring,including finger pressing,knuckle,wrist and elbow bending movements.
