Journal ArticleDOI
A Broadband Absorber With a Resistive Pattern Made of Ink With Graphene Nano-Platelets
Marzena Olszewska-Placha,Bartlomiej Salski,Daniel Janczak,Pawel Bajurko,Wojciech Gwarek,Małgorzata Jakubowska +5 more
TL;DR: In this paper, a resistive pattern printed on a dielectric spacer backed by a conducting surface is used to extend an absorption spectrum up to an octave and beyond, which is very competitive over alternative solutions.
Journal ArticleDOI
Graphene-Based Dipole Antenna for a UHF RFID Tag
Pawel Kopyt,Bartlomiej Salski,Marzena Olszewska-Placha,Daniel Janczak,Marcin Słoma,Tomasz Kurkus,Małgorzata Jakubowska,Wojciech Gwarek +7 more
TL;DR: In this article, the design and measurements of a remote frequency identification (RFID) tag built of a graphene-based dipole antenna and a chip operating in the ultra-high frequency (UHF) band in accordance with the EPC Global Class 1 Gen 2 standard is described.
Journal ArticleDOI
Screen-printed resistive pressure sensors containing graphene nanoplatelets and carbon nanotubes.
TL;DR: Experiments revealed the relationship between morphology and loading of functional phase in the polymer matrix and the sensors' sensitivity, exploiting contact resistance phenomena and evenly dispersed nanomaterials with different amount of nanoplatelets and nanotubes in the composites.
Journal ArticleDOI
Efficient Inkjet Printing of Graphene-Based Elements: Influence of Dispersing Agent on Ink Viscosity
Lucja Dybowska-Sarapuk,Konrad Kielbasinski,Aneta Arazna,K. Futera,Andrzej Skalski,Daniel Janczak,Marcin Słoma,Małgorzata Jakubowska +7 more
TL;DR: It is shown that proper, stable graphene inks adjusted for inkjet technique rheology must contain modifiers such as dispersing agents to be effectively printed.
Journal ArticleDOI
Electroluminescent structures printed on paper and textile elastic substrates
TL;DR: In this article, a reverse stack was used to print electroluminescent structures with elaborated polymer compositions filled with nanomaterials, such as carbon nanotubes and graphene platelets, dielectric and luminophore nanopowders.
