“…The stray light energy from high-order diffractions by the random mesh is significantly less than that from regularly structured meshes (square, honeycomb), which indicates the good optical performance of such random meshes. [1][2][3][4][5][6] In contrast to meshes with periodically aligned metal lines, random metal networks produce neither moiré nor starburst patterns; this property is crucial for their application in displays. [7][8][9][10][11] To characterize nanowire-based and templated transparent conductive films, the metal filling factor, f F , i.e., ratio of the metal-covered area to the total area of the film, is used.…”

We have studied the electrical conductivity of nanoring-based, transparent conductive films, these being promising elements for flexible electronic devices. Both the wire resistance and the junction resistance were taken into account. We have calculated the dependency of the electrical conductivity on the number density of the rings. We have proposed a mean-field approach to estimate the dependency of the electrical conductivity on the main parameters. Comparison of direct computations of the electrical conductivity and the estimates provided by the mean-field approach evidenced the applicability of this approach for those cases where the wire resistance dominates over the junction resistance and where both resistances are of the same order. For these two cases, both the direct computations and the mean-field approach evidenced a linear dependence of the electrical conductivity of the films on the number density of the conductive rings. By contrast, the dependence of the electrical conductivity on the number density of the conductive rings is quadratic when the junction resistance dominates over the wire resistance. In this case, the mean-field approach significantly overestimates the electrical conductivity since the main assumptions underlying this approach are no longer fulfilled.

“…205 According to different deformations, flexible electronics can be classified into a variety of types and applications, such as bending electronics, foldable electronics, etc. , 192,210 where stretchable electronics occupy a significant place. Stretchable electronics are composed of stretchable substrates, stretchable conductive materials, sticky layers, and electronic devices, and researchers place a significant deal of focus on the requirement that stretchable conductive materials maintain strong electrical conductivity throughout the stretching process, since this is a very difficult aspect of the process that defines the overall performance of stretchy electronics.…”

Electrohydrodynamic (EHD) printing technique, which deposits micro/nanostructures through high electric force, has recently attracted significant research interest owing to their fascinating characteristics in high resolution (<1 μm), wide material applicability (ink viscosity 1–10 000 cps), tunable printing modes (electrospray, electrospinning, and EHD jet printing), and compatibility with flexible/wearable applications. Since the laboratory level of the EHD printed electronics' resolution and efficiency is gradually approaching the commercial application level, an urgent need for developing EHD technique from laboratory into industrialization have been put forward. Herein, we first discuss the EHD printing technique, including the ink design, droplet formation, and key technologies for promoting printing efficiency/accuracy. Then we summarize the recent progress of EHD printing in fabrication of displays, organic field‐effect transistors (OFETs), transparent electrodes, and sensors and actuators. Finally, a brief summary and the outlook for future research effort are presented.image
