In this paper we demonstrate the use of inkjet printing as a facile digital fabrication tool for the cost effective manufacture of radio frequency (RF) features on low-cost flexible and porous substrates. The design presented in this work is a thin, substrate tolerant UHF RFID tag that can be mounted directly onto the skin surface in the form of a transfer patch in much the same way that a temporary tattoo could be applied.
