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