Wirelessly powered large-area electronics for the Internet of Things

Powering the increasing number of sensor nodes used in Internet Things creates a technological challenge. The economic and sustainability issues battery-powered devices mean that wirelessly powered operation—combined with environmentally friendly circuit technologies—will be needed. Large-area electronics—which can based on organic semiconductors, amorphous metal oxide semiconducting carbon nanotubes two-dimensional semiconductors—could provide solution. Here we examine potential large-area electronics technology development sustainable, nodes. We system-level analysis nodes, identifying constraints faced by such highlighting promising architectures design approaches. then explore use focus low-power transistor circuits for digital processing signal amplification, as well high-speed diodes printed antennas data communication radiofrequency energy harvesting. This Perspective explores Things, considering
