The use of sensors covers a wide range of applications such as the monitoring of systems and structures in automotive, marine and aerospace industries, to the subtle detection of skin and muscle movements for controlling prosthetics. Current sensor technology can be costly to manufacture, install and maintain, whilst wearable sensors can be cumbersome, requiring portable electronics. The use of printed graphic technology based sensors could potentially overcome these problems by providing rapid prototyping and mass production at low cost on flexible materials and contribute towards the development of the interconnected network of physical devices with embedded electronics which has now become known as the Internet of Things.In this project, we will develop ink-jet and screen-printed sensors using inks based on single layered two-dimensional (2D) materials, such as graphene, and carbon nanotube tube dispersions forming the conductive pathways to measure pressure changes or forces. The project will adopt ink formulations under development in the Nanofunctional Materials Group, School of Materials at the University of Manchester and from other collaborative groups. The sensors will adopt two designs - (i) resistive strain gauge and (ii) in-plane capacitive strain gauge. Pressure changes or forces will deflect a flexible substrate resulting in elastic deformation which will be measured by the surface-printed sensor. In developing these sensors it is intended that the project will work towards paving the way for printing on plastic or paper and towards showing a proof of concept for inexpensive and disposable sensors for the Internet of Things.

传感器的使用涵盖了广泛的应用，例如监测汽车，船舶和航空航天工业中的系统和结构，以及用于控制假肢的皮肤和肌肉运动的细微检测。目前的传感器技术制造、安装和维护成本很高，而可穿戴传感器可能很麻烦，需要便携式电子设备。基于传感器的印刷图形技术的使用可以通过在柔性材料上提供低成本的快速原型和大规模生产来潜在地克服这些问题，并有助于开发具有嵌入式电子设备的物理设备互联网络，现在已被称为物联网。在这个项目中，我们将开发喷墨和丝网印刷传感器，使用基于单层二维（2D）材料的墨水，如石墨烯和碳纳米管分散体形成导电通道，以测量压力变化或力。该项目将采用曼彻斯特大学材料学院纳米功能材料小组和其他合作小组正在开发的油墨配方。传感器将采用两种设计- (i)电阻应变片和（ii）面内电容应变片。压力变化或力将使柔性基板偏转，从而产生弹性变形，这将由表面印刷传感器测量。在开发这些传感器的过程中，该项目旨在为塑料或纸张打印铺平道路，并展示用于物联网的廉价一次性传感器的概念验证。
