“…[66] Jamalabadi et al used an electrospinning technique to deposit PPy and a PPy-ZnO hybrid nanocomposite, with different ZnO loading percentages, over a copper thin film to produce a novel 4-element chemiresistive sensor array. [151] The sensor was capable of identifying and quantifying different amine vapors and their respective concentrations. License.…”

New and innovative applications in the field of electronics are rapidly emerging. Such applications often require flexible or stretchable substrates, lightweight and transparent materials, and design freedom. This paper offers a complete overview concerning flexible electronics manufacturing, focusing on the materials and technologies that have been recently developed. This combination of materials and technologies aims to fuel a fast, economical, and environmentally sustainable transition from the conventional to the novel and highly customizable electronics. Organic conductors, semiconductors, and dielectrics have recently gathered lots of attention since they are compatible with printing technologies, and can be easily spread over large and flexible substrates. These printing technologies are usually simple and fast procedures, which rely on low‐cost and recycle‐friendly materials, intended for large‐scale fabrication. Overall, even though organic large‐area electronics manufacturing is still in its early stages of development, it is a field with tremendous potential that holds promise to revolutionize the way products are designed, developed, and processed from the factory premises to the consumers’ hands. Besides, this technology is highly versatile and can be applied to a large array of sectors such as automotive, medical, home design, industrial, agricultural, among others.

“…With the attempt of different kinds of preparation methods, a variety of conducting polymer/metal oxide nanocomposites with form of thin films , particles [29][30][31][32], fibers [33][34][35][36], irregular shapes [37], sheets [38], short rods [39], tubes [40], flowers [41], networks [42][43][44] and core@shells [45,46] have been synthesized and applied to gas sensors successively. Taking PANI based nanocomposites for example, as early as 2007, Jiang et al [25] successfully prepared gas sensors for NH 3 detection using hybrid PANI/TiO 2 nanocomposites.…”

“…Besides PANI, PPy is also one of the most ideal sensing candidates in the VOCs detection, since it possess obvious advantages of good environmental stability, low operating temperature, easy synthesis and reversible redox reaction [29,[54][55][56]. Generally speaking, similar to the preparation of PANI/ metal oxide nanocomposites, the typical process of preparing conductive PPy/metal oxide nanocomposites usually includes the following three steps: first, nanostructured metal oxides were prepared by chemical bath deposition and in air calcination [57], in-situ growing [38], hydrothermal synthesis, sol-gel method [54], surfactantassisted method and calcination [36,43,55], template based hydrothermal synthesis [45,56], ultrasound assisted precipitation method [29], or carbon microspheres templated method [56,58]. Then, conducting polymer was synthesized by in situ oxidative polymerization method [32], electrochemical deposition [57], chemical oxidation polymerization [29], or solution method [38,40,55].…”

With the rapid development of conductive polymers, they have shown great potential in room-temperature chemical gas detection, as their electrical conductivity can be changed upon exposure to oxidative or reductive gas molecules at room temperature. However, due to their relatively low conductivity and high affinity toward volatile organic compounds and water molecules, they always exhibit low sensitivity, poor stability, and gas selectivity, which hinder their practical gas sensor applications. In addition, inorganic sensitive materials show totally different advantages in gas sensors, such as high sensitivity, fast response to low concentration analytes, high surface area, and versatile surface chemistry, which could complement the conducting polymers in terms of the sensing characteristics. It seems to be a win-win choice to combine inorganic sensitive materials with polymers for gas detection due to their synergistic effects, which has attracted extensive interests in gas-sensing applications. In this review, we summarize the recent development in polymer-inorganic nanocomposite based gas sensors. The roles of inorganic nanomaterials in improving the gas-sensing performances of conducting polymers are introduced and the progress of conducting polymer-inorganic nanocomposites including metal oxides, metal, carbon (carbon nanotube, graphene), and ternary composites are presented. Finally, a conclusion and a perspective in the field of gas sensors incorporating conducting polymer-inorganic nanocomposite are summarized.

This paper presents a novel electronic nose (E-nose) data pre-processing method, based on a recently developed non-parametric kernel-based modelling (KBM) approach. The proposed method is tested by an automated odour detection and classification system, named "NOS.E", developed by the NOS.E team in University of Technology Sydney. Experimental results show that when extracting the derivative-related features from signals collected by the NOS.E, the proposed non-parametric KBM odour data pre-processing method achieves more reliable and stable pre-processing results comparing with other pre-processing methods such as wavelet package correlation filter (WPCF), mean filter (MF), polynomial curve fitting (PCF) and locally weighted regression (LWR). Based on these derivative-related features, the NOS.E can achieve a 96.23% accuracy of classification with the popular Support Vector Machine (SVM) classifier.
