“…Many of the functionalities of these materials, such as their ultrahigh sensitivity, room-temperature workability, and high transparency, have already been improved. [8][9][10][11] However, like other wearable devices, flexible chemiresistors still have some shortcomings such as difficulty in controlling power usage because operation at lower power level for reduction in power consumption can cause degradation in device performance (i.e., slower response speed, lower resolution, etc.). [12,13] Therefore, in addition to device miniaturization methods to reduce power consumption, developing better sensing materials to enhance the sensing performance is also necessary for wearable electronics.…”

Flexible chemical sensors utilizing chemically sensitive nanomaterials are of great interest for wearable sensing applications. However, obtaining high performance flexible chemical sensors with high sensitivity, fast response, transparency, stability, and workability at ambient conditions is still challenging. Herein, a newly designed flexible and transparent chemical sensor of reduced graphene oxide (R‐GO) coupled with organic dye molecules (bromophenol blue) is introduced. This device has promising properties such as high mechanical flexibility (>5000 bending cycles with a bending radius of 0.95 cm) and optical transparency (>60% in the visible region). Furthermore, stacking the water‐trapping dye layer on R‐GO enables a higher response as well as workability in a large relative humidity range (up to 80%), and dual‐mode detection capabilities of colorimetric and electrical sensing for NH3 gas (5–40 ppm). These advantageous attributes of the flexible and transparent R‐GO sensor coupled with organic dye molecules provide great potential for real‐time monitoring of toxic gas/vapor in future practical chemical sensing at room conditions in wearable electronics.

“…For instance, transparent electrode is a necessary component in many modern devices such as touch screens, LCDs, OLEDs, and solar cells [31][32][33]. The most common transparent substrates are tin and fluorine doped indium oxide (ITO and FTO), which possess the advantages of innate transparency (~90% in visible region), high electrical conductivity (~10 4 S cm −1 ), and chemical inertness [34].…”

The need for the development of efficient electrochemical energy storage devices with high energy density, power density and safety is becoming more and more urgent in recent years, and the key for achieving the outstanding performance is the suitable structural designing of active materials. Nanoarray architecture emerged as one of the most promising structures, as it can offer many advantages to boost the electrochemical performance. Specifically, this kind of integrated electrodes can provide a large electrochemically active surface area, faster electron transport and electrolyte ion diffusion, leading to substantially improved capacitive, rate and cycling performances. In this paper, we will review the recent advances in strategies for synthesis of materials with nanoarray architectures and their applications in supercapacitors and batteries.

“…However, with the rapidly development of flexible thin-film optoelectronic devices and the inherent brittleness of ITO, great efforts have been made in materials science to develop new highly flexible transparent conductive film (TCF) materials to replace ITO, including carbon nanotubes (CNTs) [2], highly conductive polymers [3,4], reduced graphene oxides (RGOs) [5], printed metal grids [6], and random networks of metallic nanowires [7][8][9]. Among these alternatives, silver nanowires (AgNWs) networks exhibit optoelectronic performances mostly close to that of ITO due to the best intrinsic electrical (6.3 9 10 7 S m -1 ) conductivity of silver and unusual optical properties as one-dimensional nanostructures, thus are regarded as one of the most promising candidate to replace ITO [10].…”

Silver nanowires (AgNWs) with 200-570 nm in diameter and 20-70 lm in length were successfully synthesized by a polyol process. The transparent conductive and flexible AgNWs films were fabricated with using the mixed cellulose eater (MCE) as matrix by the improved vacuum filtration process. Then, the optical and electrical and mechanical properties of the AgNWs-MCE films were investigated. For the AgNWs-MCE film produced with a deposition density of 152 mg m -2 , the optical transmission at 550 nm is 81.98 % with R s around 312 X sq -1 , whereas at a deposition density of 190 mg m -2 an AgNWs-MCE film with an optical transmission of 79.0 % at 550 nm and R s around 16.6 X sq -1 . There is little overt increase in R s of the AgNWS-MCE film after tape tests for 200 times. The bending test indicated that the change in R s of AgNWs-MCE film is less than 8 % even after 200 cycles of compressive or tensile bending. The excellent mechanical properties of the AgNWs-MCE film can be attributed to the burying of the AgNWs film at the surface of MCEs. Two 0.5 W LED lamps with series fixed on the surface of AgNWs-MCE film with conductive adhesive were lighted, and they were still luminous after bent.
