Measuring resistance of textile materials based on Van der Pauw method

Abstract

<span style="mso-ansi-language: EN-US" lang="EN-US">A new approach has been made to determine electro-conductive properties of a textile product on the basis of the idea of Van der Pauw method. This method is used to determine only two characteristic resistances associated with four electrodes. Surface resistivity of the sample is not determined because this technique requires some special conditions. The influence of the contact diameter of electrodes as well as the electrodes arrangement on the resistance value of textile sample has been studied. <span style="mso-ansi-language:EN" lang="EN">The results show that in case of selected range of the electrodes diameters, the contact diameters do not affect resistance when constant force is applied. However, the impact of electrodes <span style="mso-ansi-language:EN-US" lang="EN-US">arrangement<span style="mso-ansi-language:EN" lang="EN"> on the resistance measurements is found to be noticeable. A<span style="mso-ansi-language:EN-US" lang="EN-US">nisotropy of electrical properties of the textile sample is also studied.
