Journal ArticleDOI
Passive uhf rfid strain sensor tag for detecting limb movement
TL;DR: A strain sensor tag with screen printed antenna for seamless integration with clothing is examined to provide a wireless method for monitoring of human body movements and the strain response is found to be a monotonic function of the strain.
Proceedings ArticleDOI
Possibilities of 3D direct write dispensing for textile UHF RFID tag manufacturing
TL;DR: In this paper, the possibilities of 3D direct write dispensing in the manufacturing of UHF RFID tags on textile materials and present considerations regarding the process parameters to achieve high-performance tags when the antenna is deposited directly on the rough and porous textile material.
Proceedings ArticleDOI
Design and RFID signal analysis of a meander line UHF RFID tag antenna
Toni Bjorninen,M. Nikkari,Leena Ukkonen,Fan Yang,Atef Z. Elsherbeni,Lauri Sydanheimo,Markku Kivikoski +6 more
TL;DR: In this paper, a meander line UHF RFID tag antenna with an efficient matching network has been designed for wideband matching and good radiation properties with small antenna size by increasing the structurepsilas electrical length by meander structure and thus lowering its self-resonant frequency.
Journal ArticleDOI
Optically Transparent Flexible Robust Circularly Polarized Antenna for UHF RFID Tags
Abu Sadat Md. Sayem,Duc Le,Roy B. V. B. Simorangkir,Toni Bjorninen,Karu P. Esselle,Raheel M. Hashmi,Maxim Zhadobov +6 more
TL;DR: In this paper, an optically transparent and flexible radio frequency identification passive tag antenna operating in the ultra high frequency band and exhibits circular polarization is presented, which is thin, lightweight, and completely encapsulated inside transparent polymer, which protects it against dust, water, heat, and mechanical stress.
Proceedings ArticleDOI
Wearable passive UHF RFID tag based on a split ring antenna
TL;DR: The results show that the split ring antenna provides stable performance for the tag placed at different distances from the body, as well as in air, an advantageous feature for cloth-integrated tags with generally unspecified antenna-body separation.
