Outline of Final Research Achievements

Chipless RFID technology has been attracting attention in recent years to reduce the RFID cost. The purpose of this research is to research and develop a chipless RFID technology that can be fabricated with a commercial inkjet printer, can be used immediately after printing, and has an information writing function. In this research, we developed chipless RFID that uses a two-dimensional conductive pattern to put information on itself and is readable and writable using a coil array. The most significant feature is non-contact information writing, which is realized with performance deterioration of the conductive pattern. Overcurrent in a bit structure induced by a near magnetic field can cause the deterioration.

Academic Significance and Societal Importance of the Research Achievements

RFID技術の確立は、物流管理や電子マネー、アクセスコントロールなど多くのものをデジタル化してきた。あらゆるモノに加えて、書類をその一枚一枚に至るまで管理するような時代がやって来ようとしている。
本課題は、RFIDをより低コスト化するためのチップレスRFID技術において、単なる性能向上に取り組んだものではなく、これまでチップレスRFIDでは実現できなかった非接触情報書き込みを実現したものであり、チップレスRFIDの可能性を大きく広げる研究であると自負している。過電流を使用するという独創的なアプローチが本手法の実現につながった。
