Environmentally friendlier printable conductive and piezoresistive sensing mate...
Franco, Miguel Alexandre Martins; Motealleh, Azadeh; Costa, Carlos Miguel Silva; Perinka, Nikola; Ribeiro, Clarisse Marta Oliveira; Tubio, Carmen R.Flexible and conformable conductive composites have been developed using different polymers, including water-based polyvinylpyrrolidone (PVP), chemical-resistant polyvinylidene fluoride (PVDF), and elastomeric styrene-ethylene-butylene-styrene (SEBS) reinforced with nitrogen-doped reduced graphene oxide with suitable viscosity in composites for printable solutions with functional properties. Manufactured by scr...
Multifunctional touch sensing and antibacterial polymer-based core-shell metall...
Costa, Pedro; Polícia, Rita; Perinka, Nikola; Alesanco, Yolanda; Viñuales, Ana; Carvalho, Estela; Pereira, Nelson; Fernandes, Margarida Maria MacedoThe transmission of bacterial infections through contaminated surfaces is nowadays an increasing source of concern, also related to the current pandemic situation. Functional materials that prevent the adhesion of microorganisms and/or induce their eradication thus avoiding fomite transmission are highly needed. In this work, a highly antimicrobial hybrid with sensorial capability is developed to be further app...
Environmentally friendly conductive screen‐printable inks based on N‐Doped grap...
Franco, Miguel; Motealleh, Azadeh; Costa, Carlos M.; Hilliou, L.; Perinka, Nikola; Ribeiro, Clarisse; Viana, Júlio César; Costa, PedroThe development of polymer-based conductive inks has gained increasing interest in the areas of printed and molded electronics. Graphene-based materials are explored in this scope, reduced graphene oxide (rGO) being among the most used conductive filler components of the inks. Herein, rGO is doped with nitrogen to obtain N-rGO; the replacement of oxygen atoms by nitrogen ones increases the electrical conductivi...
All-Printed piezoresistive sensor matrix with organic thin-film transistors as ...
Correia, Vitor; Oliveira, Juliana; Perinka, Nikola; Costa, Pedro; Sowade, Enrico; Mitra, Kalyan Y.; Baumann, Reinhard R.; Lanceros-Méndez, S.A generation of piezoresistive sensors (force or deformation) fully processed by printing technologies is increasingly being implemented in applications due to advantages as a large-area application, simple device, integration, and high flexibility. This work reports the development of a fully printed piezoresistive (5 × 5 sensor) matrix in which an organic thin-film transistor (OTFT) is placed in each sensor t...
