The Impact of Elongation on Change in Electrical Resistance of Electrically Conductive Yarns Woven into Fabric [PDF]

open access: yesMaterials, 2021
Electrically conductive yarns (ECYs) are gaining increasing applications in woven textile materials, especially in woven sensors suitable for incorporation into clothing. In this paper, the effect of the yarn count of ECYs woven into fabric on values of electrical resistance is analyzed.

Quantum conductance and electrical resistivity [PDF]

open access: yesPhysics Letters A, 2006
The Landauer formula for quantum conductance, based on the modern paradigm: "conduction is transmission", is generalized to samples of macroscopic size. Two regimes of electrical conduction, namely diffusive and ballistic ones, are studied. In the former regime, Drude's formula for the electrical resistivity is recovered and it is found a maximum ...

Mapping the conductivity of graphene with Electrical Resistance Tomography [PDF]

open access: yesScientific Reports, 2019
AbstractElectronic applications of large-area graphene films require rapid and accurate methods to map their electrical properties. Here we present the first electrical resistance tomography (ERT) measurements on large-area graphene samples, obtained with a dedicated measurement setup and reconstruction software.

Chemically Resistant, Electric Conductive, and Superhydrophobic Coatings [PDF]

open access: yesAdvanced Materials Interfaces, 2019
AbstractIn this study, the fabrication of superhydrophobic and conductive coatings applying a facile coating method is reported. The droplet‐assisted growth and shaping (DAGS) method is used to synthesize silicone nanofilament–based superhydrophobic coatings.
