An electronic nose using conductometric gas sensors based on P3HT doped with triflates for gas detection using computational techniques (PCA, LDA, and kNN)

Aicha Boujnah, Aimen Boubaker, Sébastien Pecqueur, Kamal Lmimouni, Adel Kalboussi

This study presents the development of an electronic nose comprising eight homemade sensors with pure P3HT and doped with different materials. The objective is to electronically identify the gases exposed on these sensors and evaluate the accuracy of target-gas classification. The resistance…

Theoretical modeling of dendrite growth from conductive wire electro-polymerization

Ankush Kumar, Kamila Janzakova, Yannick Coffinier, Sébastien Pecqueur, F. Alibart

Abstract Electropolymerization is a bottom-up materials engineering process of micro/nano-scale that utilizes electrical signals to deposit conducting dendrites morphologies by a redox reaction in the liquid phase. It resembles synaptogenesis in the brain, in which the electrical stimulation in the…

A flexible and wearable dual band bio-based antenna for WBAN applications

Abdelghafour Sid, Pierre-Yves Cresson, Nicolas Joly, Flavie Braud, Tuami Lasri

This paper presents a flexible and wearable (on-body) dual band antenna operating in two Industrial, Scientific and Medical (ISM) frequency bands. The central frequencies selected are equal to 2.45 GHz and 5.8 GHz. In order to make the antenna suitable for Wireless Body Area Network (WBAN)…

Tunable Topological Acoustic Tamm States in Comblike Structures Based on Band Inversion around Flat Bands

Soufyane Khattou, Yamina Rezzouk, Madiha Amrani, Mohamed El Ghafiani, El Houssaine El Boudouti, Abdelkrim Talbi, Bahram Djafari-Rouhani

We investigate the existence of acoustic Tamm states at the interface between two one-dimensional (1D) comblike phononic crystals (PnCs) based on slender tubes and discuss their topological or trivial character. The PnCs consist of stubs grafted periodically along a waveguide and the two crystals…
