摘要：

针对织物基柔性压力传感器制备过程中存在工艺复杂、成本高等问题,提出在平纹棉织物上下表面贴附等宽叉指形铜箔,并采用聚二甲基硅氧烷(PDMS)封装织物及铜箔电极,制得织物基电容式柔性压力传感器的方法,对传感器阵列单元截面微观形貌进行观察并对传感器性能进行测试。结果表明, 传感器具有PDMS包覆织物纤维特殊微结构复合介电层;在0~0.75、0.75~125及125~580 kPa范围内,灵敏度分别为8.66×10-3、0.94×10-3和0.43×10-3 kPa-1,传感器最大可检测限达580 kPa,最大迟滞约5.5%,具有良好的重复性及稳定性;对其柔性及触觉分析发现,该传感器可清晰识别并反馈弯折不同角度及手指间歇触压的过程。

Abstract:

In order to solve the existing problems such as complex process and high cost in the preparation of fabric-based flexible pressure sensors, a new method was proposed for preparing a fabric-based capacitive flexible pressure sensor by affixing equal width interdigital copper foil on both sides of the plain woven cotton fabric and encapsulating the assembly using polydimethylsiloxane (PDMS). The microscopic morphology of the cross-section of the sensor array unit was observed, and the sensor performances were tested. Experiment results show that it has a special microstructure composite dielectric layer formed by PDMS coated fabric fibers, and its sensitivities are about 8.66×10-3, 0.94×10-3 and 0.43×10-3 kPa-1 under pressures of 0-0.75, 0.75-125 and 125-580 kPa respectively. The maximum detectable limit of the sensor can reach 580 kPa, whose maximum hysteresis is about 5.5%, and the sensor demonstrates good repeatability and stability. The flexibility and tactile testing show that it can clearly recognize and feedback the process of bending with different angles and intermittent finger pressing.

Key words: smart textiles, fabric-based capacitive sensor, flexible sensor, polydimethylsiloxane, dielectric layer of composite microstructure
