This letter presents the proof-of-concept of the fabrication and performance analysis of a flexible and stretchable wearable antenna on a three-dimensional (3-D) printed substrate. It presents the details of the 3-D printing of the substrate, brush-painting of the antenna, as well as the simulation and measurement results of the antenna. In addition, the bending test is done to check the limitation...
We characterize two nanoparticle inks for the fabrication of low-cost passive UHF RFID tags on a novel polyester-based substrate (Flexcon THERMLfilm). We developed optimized printing parameters for Silver (Harima NPS-JL) and Copper (ANI Cu-IJ70) inks, fabricated the tag antennas and sintered them using thermal and photonic sintering. The tag performance is evaluated through wireless tag measurements,...
The need for novel substrate materials and optimized additive manufacturing methods is growing fast as new applications are developed constantly, especially along the emerging paradigm of the Internet of Things. This paper presents a comparison of thermal and inkjet printing for the fabrication of passive UHF RFID tag antennas on commonly used polyimide (Kapton) and on novel polyester-based substrate...
This study is related to fabrication and characterization of redox conductive bridge memristors (RCBM). An active region in RCBM is formed by chalcogenide glass (ChG) doped with silver (Ag). We report the application of plasma enhanced chemical vapor deposition (PECVD) method for depositing ChG films which gives the advantage of flexibility in the composition and structure not easily achieved with...
