Fully Inkjet Printed 60GHz Backscatter 5G RFID Modules for Sensing and Localization in Internet of Things (IoT) and Digital Twins Applications

The exponentially increasing demand for low-cost and high performance wireless devices and modules as a part of the proliferation of the Internet of Things (IoT) and digital twins has made investigation into efficient means of manufacturing and integration of these devices necessary. In this effort, the authors report a simple low cost RFID module operating in the 60GHz Industrial, Scientific and Medical (ISM) band equipped with an ultra sensitive flex sensor. The reported system is capable of detecting continuous flexing of the sensor while simultaneously able to report it's range to within 5 mm of error. In addition to the device presented, this work outlines a simple low cost additive manufacturing procedure that enables integration of the sensor with a communicating node in a single process.
