Multi-dimensional accurate response and smooth signal transmission are critical challenges in the advancement of multi-resolution recognition and complex environment analysis. Inspired by the structure-activity relationship between discrepant microstructures of the spiral and radial threads in a spider web, we designed and printed graphene with porous and densely-packed microstructures to integrate into a multi-resolution graphene tactile sensor. The three-dimensional (3D) porous graphene structure performs multi-dimensional deformation responses. The laminar densely-packed graphene structure contributes excellent conductivity with flexible stability. The spider-web inspired printed pattern inherits orientational and locational kinesis tracking. The multi-structure construction with homo-graphene material can integrate discrepant electronic properties with remarkable flexibility, which will attract enormous attention for electronic skin, wearable devices and human-machine interactions.
多维精确响应和信号的平稳传输是多分辨率识别和复杂环境分析发展的关键挑战。受蜘蛛蛛网中螺旋形和放射状线迹的不同微观结构之间的结构-活性关系的启发，我们设计并打印了具有多孔且密集微观结构的石墨烯，将其集成到多分辨率石墨烯触觉传感器中。三维（3D）多孔石墨烯结构可实现多维变形响应。层状密集石墨烯结构具有出色的导电性和灵活的稳定性。受蜘蛛网启发的打印图案具有定向和定位运动跟踪功能。具有同质石墨烯材料的多结构构造可以将不同的电子性能与显著的灵活性集成在一起，这将为电子皮肤、可穿戴设备和人机交互吸引巨大的关注。
