Abstract

Highlights

A blade-coated composite paste, composed of a compressible 3D carbon skeleton, PEDOT:PSS, and CNTs, can naturally dry to form a porous electrode on paper with a micro- and nano-structured surface.
The all-paper pressure sensor demonstrated an ultrahigh sensitivity of 1014 kPa⁻¹, a wide responsive range up to 300 kPa, and an ultralow operating voltage of 0.01 V.
The sensor showcased superior detection capability, ranging from subtle wrist pulses and robust finger taps to large-area spatial force.

刀片涂层多孔三维碳复合电极与多尺度界面相结合，用于高灵敏度全纸压力传感器。

灵活、可穿戴的压力传感器在健康监测、疾病检测和术后康复方面大有可为。开发具有高灵敏度、宽检测范围和成本效益的压力传感器至关重要。本文利用纸张的可持续性、生物兼容性和固有的多孔结构，设计了一种性能卓越的溶液加工全纸电阻式压力传感器。由可压缩三维碳骨架、导电聚合物聚（3,4-亚乙二氧基噻吩）:聚（苯乙烯磺酸）和内聚碳纳米管组成的三元复合浆料被刀片涂布在纸上并自然干燥，从而形成具有分层微观和纳米结构表面的多孔复合电极。结合粗糙纸张上亚毫米级指宽的丝网印刷铜电极，在电极之间形成了多尺度分层接触界面，显著提高了灵敏度（1014 kPa-1），并扩大了低检测限和低功耗全纸压力传感器的检测范围（高达 300 kPa）。其多功能性涵盖了从细微的腕部脉冲、有力的手指敲击到大面积空间力检测，凸显了其复杂的亚毫米-微米-纳米分层界面和复合电极中的纳米孔隙率。最终，这种全纸电阻式压力传感器凭借其卓越的传感能力、大规模制造潜力和成本效益，为下一代可穿戴电子产品铺平了道路，开创了一个先进的可持续技术解决方案时代。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
