Modern technology demands increasingly larger number of new materials to suit the specific requirement of the particular applications. The search for new materials, or even better, for materials with tuneable properties, has dramatically intensified over the last decade. The best strategy here are the composite materials and heterostructures, which allow ultimate tuning of material parameters, combinations of otherwise unmatchable properties and can provide multiple functionalities. However, usually such materials are not readily accessible due to cost and the complex technology required for assembly/production of such structures. Here we propose a new paradigm in creating such composite materials: heterostructures based on 2D atomic crystals, which can be assembled by mass-production means. This way we will decouple the performance of particular devices from the properties of naturally available materials. The ultimate goal is to develop a new paradigm of "materials on demand" with properties precisely tailored for novel complex architectures and structures. The ground-breaking nature of our research and the development of the mass-production technique of the production of such heterostructures will have huge impact on future technology. We will also demonstrate prototypes of multifunctional devices which are based on such a technology. Examples of devices we are planning to create are temperature, humidity, light, strain and many other sensors which will be battery-free and powered by absorbing radio waves (RFID technology, also enabled by printed electronics) for remote sensing applications. Such wirelessly interconnected tuneable sensors and actuators can create a platform for the fast-growing "Internet of Things" paradigm.2D atomic crystals are one atom thick materials. The family of such crystals is very large and includes transition metal dichalcogenides, hexagonal boron nitride, graphene among many others. Collectively, they cover a large range of properties: from conductive to insulating, from transparent to opaque, from mechanically stiff to compliant. Also, very often the properties of such 2D crystals are very different from the properties of their 3D precursors. Interestingly, many of the unique properties of the 2D crystals are preserved even when we create suspensions (2D inks) out of these materials. Such inks can be used for deposition of the 2D materials to any surfaces, creating low-cost, conformal functional coating. Still, the most important property of materials in this family is the possibility to assemble them into 3D stacks, creating novel heterostructures. Such heterostructures have proven to have new functionalities (tunnelling transistors, LED, etc) or even combinations of several functionalities. The large selection of 2D crystals, ensures that the parameters of such heterostructures can be tuned in a wide range.In this project we propose to develop a low-cost technique to be able to print such heterostructures from 2D inks. Several members of the consortium have already demonstrated that tunnelling diodes, tunnelling transistors and photodetectors can be printed using standard mass-production technologies. We will significantly increase the range of heterostructures produced by such methods, and will specifically concentrate on heterostructures which produce active response (thermo-power, piezoelectric, photovoltaic, etc). Such heterostructures can act as sensors in a number of applications. We will then combine this technology with already developed technique of printing RFID antenna by using graphene inks. This would allow us to create RFID sensors of different types which do not require power source. For instance, we can record temperature of a product or illumination this product has been subjected to. Multifunctional sensors can naturally be achieved with such technique (for instance temperature, strain and humidity could be recorded at the same time).

现代技术需要越来越多的新材料来满足特定应用的特定要求。在过去的十年里，对新材料，甚至更好的具有可调性能的材料的研究已经大大加强。这里的最佳策略是复合材料和异质结构，它们允许最终调整材料参数，组合其他不可匹配的特性，并可以提供多种功能。然而，由于成本和组装/生产这种结构所需的复杂技术，通常这种材料不容易获得。在这里，我们提出了一个新的范例，在创造这样的复合材料：异质结构的基础上的二维原子晶体，它可以组装的大规模生产手段。通过这种方式，我们将使特定设备的性能与自然可用材料的性能脱钩。最终目标是开发一种新的“按需材料”范例，其性能可精确地为新型复杂的建筑和结构量身定制。我们研究的突破性和这种异质结构的大规模生产技术的发展将对未来技术产生巨大影响。我们还将展示基于这种技术的多功能设备的原型。我们正在计划创建的设备的例子是温度，湿度，光，应变和许多其他传感器，这些传感器将是无电池的，并通过吸收无线电波（RFID技术，也可以通过印刷电子）为遥感应用提供动力。这种无线互连的可调传感器和致动器可以为快速发展的“物联网”范例创建一个平台。2D原子晶体是一个原子厚的材料。这种晶体的家族非常大，包括过渡金属二硫属化物、六方氮化硼、石墨烯等。总的来说，它们涵盖了广泛的特性：从导电到绝缘，从透明到不透明，从机械刚性到顺应性。而且，这种2D晶体的性质通常与其3D前体的性质非常不同。有趣的是，即使我们用这些材料制造悬浮液（2D墨水），2D晶体的许多独特特性也得到了保留。这种油墨可用于将2D材料沉积到任何表面，从而产生低成本的保形功能涂层。尽管如此，这个家族中材料最重要的特性是将它们组装成3D堆栈的可能性，从而创造出新颖的异质结构。这样的异质结构已被证明具有新的功能（隧穿晶体管、LED等）或甚至几种功能的组合。2D晶体的大量选择确保了这种异质结构的参数可以在很宽的范围内进行调整。在这个项目中，我们建议开发一种低成本的技术，能够从2D墨水打印这种异质结构。该联盟的几个成员已经证明，隧道二极管，隧道晶体管和光电探测器可以使用标准的大规模生产技术印刷。我们将显著增加通过这种方法产生的异质结构的范围，并且将特别集中于产生主动响应（热电、压电、光伏等）的异质结构。这种异质结构可以在许多应用中用作传感器。然后，我们将联合收割机与已经开发的使用石墨烯油墨印刷RFID天线的技术相结合。这将使我们能够创建不需要电源的不同类型的RFID传感器。例如，我们可以记录产品的温度或该产品受到的光照。多功能传感器自然可以通过这种技术实现（例如，温度，应变和湿度可以同时记录）。
