We provide a review of cellular graphene (CG), from its fabrication, to characterization of mechanical properties, to applications in strain and pressure sensing. Although several recent reviews have briefly surveyed various types of strain and pressure sensors fabricated from common one-dimensional or two-dimensional (2D) nanomaterials such as carbon nanotube (CNT), graphene, and metallic nanowire/nanoparticle, the emerging applications of CG in the design and development of strain and pressure sensors, as well as the structure-property-function correlations in sensing performance, have not been systematically covered. CG exhibits unique strain-sensing capabilities that collectively enable a wide range of strain sensing to be achieved. We first review several state-of-the-art approaches for fabricating CG with emphasis on the engineering of tailored mechanical properties. Second, the strain- and pressure-sensing performance of CG-based devices against a range of fabrication processes is systematically and critically analyzed. Along the way, representative applications of such CG-based sensors are thoroughly discussed. This review aims to provide basic information for the design of novel CG as well as other classes of three-dimensional porous structures fabricated from various 2D nanomaterials. In the conclusion, we highlight the extension of design principles to other 2D materials and critically summarize the key issues that need to be addressed in the future.

蜂窝石墨烯:制造,机械性能和应变传感应用

我们提供了对细胞石墨烯(CG)的概述,从其制造到机械性能的表征,再到在应变和压力感测中的应用。尽管最近的一些评论简要调查了由常见的一维或二维(2D)纳米材料(例如碳纳米管(CNT),石墨烯和金属纳米线/纳米粒子)制成的各种类型的应变和压力传感器,但CG在以下领域的新兴应用尚未系统地涵盖应变和压力传感器的设计和开发以及传感性能中的结构特性函数相关性。CG具有独特的应变感应功能,可共同实现广泛的应变感应。我们首先回顾几种制造CG的最新方法,重点是定制机械性能的工程设计。其次,系统地,严格地分析了基于CG的器件对一系列制造工艺的应变和压力感应性能。在此过程中,对此类基于CG的传感器的代表性应用进行了全面讨论。这篇综述旨在为新型CG以及由各种2D纳米材料制成的其他类别的三维多孔结构的设计提供基本信息。最后,我们重点介绍了将设计原理扩展到其他2D材料的方法,并严格总结了将来需要解决的关键问题。系统地,严格地分析了基于CG的器件在一系列制造过程中的应变和压力感应性能。在此过程中,对此类基于CG的传感器的代表性应用进行了详尽的讨论。这篇综述旨在为新型CG以及由各种2D纳米材料制成的其他类别的三维多孔结构的设计提供基本信息。最后,我们重点介绍了将设计原理扩展到其他2D材料的方法,并严格总结了将来需要解决的关键问题。系统地,严格地分析了基于CG的器件在一系列制造过程中的应变和压力感应性能。在此过程中,对此类基于CG的传感器的代表性应用进行了详尽的讨论。这篇综述旨在为新型CG以及由各种2D纳米材料制成的其他类别的三维多孔结构的设计提供基本信息。最后,我们重点介绍了将设计原理扩展到其他2D材料的方法,并严格总结了将来需要解决的关键问题。这篇综述旨在为新型CG以及由各种2D纳米材料制成的其他类别的三维多孔结构的设计提供基本信息。最后,我们重点介绍了将设计原理扩展到其他2D材料的方法,并严格总结了将来需要解决的关键问题。这篇综述旨在为新型CG以及由各种2D纳米材料制成的其他类别的三维多孔结构的设计提供基本信息。最后,我们重点介绍了将设计原理扩展到其他2D材料的方法,并严格总结了将来需要解决的关键问题。
