Interdependence between ink, substrate and sintering method on inkjet printed devices.
The present work describes the inkjet printing and low temperature sintering of silver nanoparticle inks onto transfer tattoo paper. Our approach results in features excellent resolution conductivity and, subsequently first passive UHF RFID tags functional mounted on human skin improved performance when compared to screen printed paper tags. Moreover, show similar copper etched plastic substrates. This study compares image quality (resolution) electrical two commercial optimal parameters...
This Letter presents an investigation of the effect human tissue conductivity and permittivity on performance epidermal transfer tattoo ultra-high frequency radio-frequency identification (RFID) tags. The measurements were carried out 20 individuals variations in measured dielectric properties correlate well with tag read range to a lesser extent their body mass index values. Simulation results also showed effects designed resonance RFID tag.

RFID tags are integrated into medical sticking plasters for future health monitoring applications. For compatibility with the skin, tag is fabricated from conducting Electronylon material and demonstrated to work a useful read range when placed directly on skin. purposes of this study, was defined as more than 50cm.
Transfer Tattoo RFID tags are described for person locating scenarios. The technology considered is Radio Frequency Identification (RFID) at the UHF Band where it possible to obtain wireless connection over distances of several meters using passive, or battery assisted transfers. have profile tattoos and can be mounted straight onto skin. Promising results enhancing read distances, possibly tens meters, been obtained very thin technologies.
In this paper we demonstrate the use of inkjet printing as a facile digital fabrication tool for cost effective manufacture UHF RFID transfer tattoo tags and Frequency Selective Surfaces on low-cost flexible porous substrates. Electrical morphological properties conductive features obtained from range metal nanoparticle inks low temperature sintering methods, such argon plasma photonic flash, are evaluated. Large scale potential is addressed.
