Abstract:
The irruption of Internet of Things and 5G in our society comes along with several technological challenges to overcome. From the high perspective, low-costs and environmental friendliness stand as crucial for the sake of their universal deployment, starting in the sensors and finishing in the power sources. Within these adversities, the production and maintenance of the abundant sensor nodes face costs, comprehending manufacturing and integration in mass of elements and subblocks; change or recharge of batteries, and natural resources and wastes management. In this article, we demonstrate how radio frequency energy harvesting (RFEH) and printed flexible technology (a growing technology for sensors) can solve these concerns through cost-effective mass-production and utilization of energy harvesting for the development of energy-autonomous nodes, as part of a wireless sensor network. We present as illustration a sprayed flexible relative humidity sensor powered with RFEH under the store-and-use principle.
