A synthesis of AgNP-rGO-PANI nanocomposite and its use in fabrication of chipless RFID sensor: current research progress

Abstract

Chipless RFID (Radio Frequency Identification) tag has attracted significant attention due to the low manufacturing cost. By eliminating the use of integrated circuit (IC), chipless RFID tag can offer competitive price in order to completely replace barcode systems. Besides, integration of physical parameter sensors with chipless RFID will open up a new domain for controlling and monitoring perishable items. It can also be fully printable by using inkjet-printed technology. The inkjet-printed technique is one of the most promising technological solutions for the realization of chipless RFID with low-cost advantage. Various types of conductive inks with different fillers such as metal nanoparticles, carbon nanotubes (CNT), and polymer have been developed for printed electronics. It needs deep investigation and study in designing low-cost but robust by using conductive ink on a low-cost substrate. The aim of this review is to claim research gap related to how AgNP-rGO-PANI (Silver Nanoparticle - Reduced Graphene Oxide - Polyaniline) nanocomposite has both scientific and economic advantages. The inkjet-printed method using conductive inks with nanocomposite fillers synthesized from semiconductor materials such as graphene, silver nanoparticles, and polyaniline on a thin sheet of low-cost substrate. This review provides an overview of synthesis methods of AgNP-rGO-PANI nanocomposite, structure and design of chipless RFID sensor, and chipless RFID sensor fabrication methods.
