From Identification to Sensing: RFID Is One of the Key Technologies in the IoT Field

Abstract

RFID (radio frequency identification) technology appeared nearly 70 years ago. Deployed more widely only from the early 2000s, it is now booming and its development is still accelerating. As its name indicates, its original function was the identification (of objects, animals, people) and its applications were then essentially aimed at traceability, access control and logistics. If this type of use is still relevant today with more and more new application contexts and more and more efficient RFID tags, RFID has also evolved by integrating new capabilities. These new tags, known as augmented tags, include an information capture function. With the explosion of connected objects and the emergence of the Internet of Things (IoT), this old technology that is RFID still has a promising future and will probably be more and more present in our private and professional environments in all fields: logistics, industry, agriculture, building, health and even space.

Communication Concept in Smart Grid Using Internet of Things

“…After that, it became a telecommunications satellite that enabled the transmission of communication signals actively to distant places on earth. Radio technology has continued to be developed into a form that allows tracking tags to be attached to objects and automatically identify them [24]. The Pacific NW Bell telecommunications company created a type of wireless phone in the same year that connected the device to a radio transmitter, which attached customers to operators.…”

Soft Fiber Electronics Based on Semiconducting Polymer

“…218 RFID is typically utilized by a scanner unit to transmit a certain frequency of radio wave energy to the receiver through the antenna. 219 Fabric-based antennas use soft fibers and fabrics as the dielectric substrate by incorporating conductive yarns so that communication networks can be established between the human body and surrounding wireless devices, with the advantages of conformal properties, low-cost reproducible production, and size-compatible preparation methods. 220 From the perspective of radio frequency characteristics, these features are especially important.…”

Real-Time Patient Indoor Health Monitoring and Location Tracking with Optical Camera Communications on the Internet of Medical Things

“…The idea of IoT can be traced back to 2005 when the meaning of IoT was to integrate technology into human's everyday human life [3]. Previously, radio-frequency identification (RFID) was the only technology that was considered to be a communication medium that was able to perform IoT [4]. However, IoT can consist of various sensor devices and communication interfaces deployed in local or even separated areas currently.…”
