Abstract High performance flexible pressure sensors have received tremendous attention due to the potential applications in wearable electronics and humanoid robotics. Herein, a low-cost, time-saving fabrication strategy is reported to efficiently construct highly sensitive and scalable pressure sensors based on graphene-textile. The flexible pressure sensor was prepared through a dip coating approach where the graphene ink was used as the active material and textile with ordered network structure, serves as the flexible support matrix. By increasing the number of layers of the textile, the pressure sensor could achieve a high linear sensitivity value of 0.23 kPa−1, a broad pressure range from 0 to 140 kPa, and a durability over 800 cycles. It was found that the network structure of the graphene-textile contributed to the enhancement of the sensing performance due to the piezoresistive effect resulting from the deformation of conductive graphene-textile. Moreover, by virtue of its exceptional properties, it is demonstrate that the high performance flexible pressure sensor could be further used to detect human physiological signals, such as wrist pulse, finger press detection and walking state monitoring, indicating its promising potential to flexible and wearable electronics.

一种基于石墨烯-纺织品网络结构的高性能压力传感器的简便且经济高效的制造方法

摘要 高性能柔性压力传感器由于在可穿戴电子和仿人机器人领域的潜在应用而受到了极大的关注。在此，据报道，一种低成本、省时的制造策略可有效构建基于石墨烯织物的高度灵敏且可扩展的压力传感器。柔性压力传感器是通过浸涂方法制备的，其中石墨烯墨水用作活性材料，具有有序网络结构的纺织品用作柔性支撑基质。通过增加织物的层数，压力传感器可以实现 0.23 kPa-1 的高线性灵敏度值、0 到 140 kPa 的宽压力范围以及超过 800 次循环的耐用性。研究发现，石墨烯织物的网络结构由于导电石墨烯织物变形导致的压阻效应而有助于提高传感性能。此外，凭借其卓越的性能，证明了高性能柔性压力传感器可进一步用于检测人体生理信号，如手腕脉搏、手指按压检测和步行状态监测，表明其在柔性和可穿戴方面具有广阔的潜力。电子产品。
