摘要

本文提出了一种基于印制在织物上的交叉电容(IDCs)的电纺织压力传感器的系统方法。在这项研究中,我们提出了一种基于多孔Ecoflex、碳纳米管(CNTs)和交叉指状电极组合的高灵敏度、宽量程压力传感器。首先,利用高精度LCR仪在1 ~ 300 kHz的频率范围内,用银墨水在棉和涤纶织物上完成了交叉电容的表征。考虑了织物对传感器灵敏度性能的影响。其次,估算和优化了CNTs的体积分数和气隙对复合材料性能的影响。体积分数CNTs的存在增强了复合材料的结合强度,改善了传感器的变形能力。在400千帕的高压下进行了超过20,000次的测试,证明了该传感器的稳健性。第三,CNTs与多孔介质的结合实现了较宽的检测范围(400 kPa),灵敏度范围从0.035 (400 kPa)到0.15 \({\mathrm{KPa}}^{-1}\) (50 kPa)。最后,通过对棉质衬底和聚酯衬底的比较表明,选择合适的介质衬底会影响传感器的灵敏度和信号输出。

Wearable capacitive pressure sensor using interdigitated capacitor printed on fabric

This paper presented a systematic approach to electro-textile pressure sensors dependent on interdigitated capacitors (IDCs) printed on fabric. In this study, we proposed a highly sensitive, broad-range pressure sensor based on the combination of porous Ecoflex, carbon nanotubes (CNTs), and interdigitated electrodes. Firstly, characterizations of the interdigitated capacitor using silver ink on Cotton and Polyester fabric were completed by precision LCR meter across the frequency range from 1 to 300 kHz. The effect of the fabric on the performance of sensor sensitivity was included. Secondly, estimating and optimizing the volume fraction of CNTs and air gaps on the properties of composites are included. The presence of volume fraction CNTs enhanced the bond strength of composites and improved sensor deformability. The robustness of the presented sensor was demonstrated by testing under high pressure at 400 kPa for more than 20,000 cycles. Thirdly, the combination of CNTs and porous dielectric achieved a broad detection range (400 kPa) with a sensitivity range from 0.035 (at 400 kPa) to 0.15 \({\mathrm{KPa}}^{-1}\) (at 50 kPa). Finally, the Cotton and Polyester substrate comparison demonstrates that selecting a suitable dielectric substrate affects sensor sensitivity and signal output.
