A disruptive solution for sensing the activity of electrical devices connected to the home power line, based on the use of a long range UHF RFID system, is proposed. The solution uses a flexible RFID tag sensor wrapped around the power cord of the electrical device to be sensed. In addition to the identification of the device, the RFID tag has the unique property of detecting the status change, th...

Radio-Frequency Identification (RFID) is the use of radio waves and electromagnetic fields to automatically read information stored on tags which are attached to objects for identification. A RFID system can be made up of three components: readers, tags and application software. A RFID reader is a device used to gather information from RFID tags, while RFID tags are the core of a RFID system, beca...

NEAR-FIELD radio frequency identification (NF-RFID) systems are being widely used for item-level tagging in pharmaceutical and retailing industries [1]. Since in NF applications the tag detection has to be limited within an assigned confined volume close to the antenna surface, a proper reader antenna design is required. A number of solutions for NF UHF RFID reader antennas have been proposed. Ant...

It is well known that UHF RFID, one of the key technologies of Internet of Things, is becoming the mainstream research of RFID applications. In a RFID system, reader plays an important role, however, RFID reader with only one channel often cannot satisfy the application requirements due to the complicated working environment. Since the working environment of the RFID reader is becoming more and mo...

UHF RFID is a technology for wireless data transmission which operates on frequencies in the UHF domain (ranging from 400MHz to 950MHz). By introducing UHF RFID technology, vehicle identification can be performed at distances of more than 10m. The line of sight between identifier and reader is not required. Large number of RF identifiers can be read at once. Thanks to UHF RFID technology, there is...
