The 4th Industrial Revolution (4IR) builds on the Internet-of-Things (IoT) paradigm, as it relies upon the scenario of having billions of interconnected autonomous mobile devices, with unprecedented processing power, storage capacity and access to knowledge. At the same time, the 4IR should be increasingly eco-friendly, by exploiting technological breakthroughs in everyday life (such us artificial intelligence, wireless communication and quantum computing). The biggest bottleneck for 4IR is that in most situations, IoT devices/networks will be remotely deployed, so that maintenance may be either inconvenient or impossible. This implies that IoT devices either have to embed energy sources consistent with their operative lifespan or that clean and renewable energy convertors must sit on board. The significant broadening of the wireless communication spectrum in Europe makes the Radio frequency (RF) energy scavenging a highly desirable way forward for clean powering of the next generation IoT. NANO-EH has the ambitious vision of creating a pathway for translating forefront knowledge of unique high frequency properties of emerging classes of nanomaterials into advanced device engineering for scalable miniaturized energy harvesting/storage submodules. This target will be reached by developing non-toxic and rare earth/lead-free materials exhibiting CMOS-compatibility and scalability for low cost and large-scale manufacturing.
