Printed Wireless Sensing Devices using Radio Frequency Communication

Abstract

Sensing technology in the Internet-of-Things (IoT) era is one of the key elements in the next industrial revolution. Especially, wireless sensors enable monitoring of various physical and chemical changes through wireless communication in applications like robotics, wearable devices, and biomedical and environmental sensing. Radio Frequency (RF) wireless sensors fabricated by printing methods with conductive materials have been recently spotlighted thanks to lots of benefits that they can provide like a simple operation, cost-effectiveness, customization, etc. Here, we focus on recent studies dedicated to the advances in various RF sensing technologies fabricated by cutting-edge printing methodologies for the realization of desired properties. By capturing recent developments in wireless sensor designs, sensing mechanisms, sensing performance, and printing materials, this Spotlight foresees the future direction of wireless RF sensors printed by industry-proven technologies in different applications.
