UHF electromagnetic structures inkjet printed on temperature sensitive substrates: A comparative study of conductive inks and sintering methods to enable low cost manufacture

Abstract

In this paper we demonstrate the use of inkjet printing as a facile digital fabrication tool for the cost effective manufacture of UHF RFID transfer tattoo tags and Frequency Selective Surfaces on low-cost flexible and porous substrates. Electrical and morphological properties of conductive features obtained from a range of metal nanoparticle inks and low temperature sintering methods, such as argon plasma and photonic flash, are evaluated. Large scale potential is addressed. ©2013; Society for Imaging Science and Technology.
