In this study, integrated plaster‐like micro‐supercapacitors based on medical adhesive tapes are fabricated by a simple pencil drawing process combined with a mild solution deposition of MnO2. These solid micro‐supercapacitors not only exhibit excellent stretchability, flexibility, and biocompatibility, but also possess outstanding electrochemical performances, such as exceptional rate capability...
In article number 1803970, Xiaoning Zhao, Haiyang Xu, and co‐workers achieve a biocompatible resistive switching memory with pectin extracted from natural orange peel. The memory with flexible and multilevel characteristics is designed to dissolve rapidly in deionized water, which possesses promising potential to be applied in high‐density secure storage systems, flexible electronics, and green electronics...
Transient electronics that can physically vanish in solution can offer opportunities to address the ecological challenges for dealing with the rapidly growing electronic waste. As one important component, it is desirable that memory devices combined with the transient feature can also be developed as secrecy information storage systems besides the above advantage. Resistive switching (RS) memory is...
In article number 1804701, Jiazhao Wang and co‐workers fabricate a quasi‐solid‐state electrolyte (PS‐QSE) for flexible lithium–oxygen (Li–O2) batteries based on an integrated solid‐state design by taking advantage of the component‐interaction between poly(vinylidene fluoride‐co‐hexafluoropropylene) and nano‐fumed silica in polymer matrix. The PS‐QSE based Li–O2 battery shows excellent cycling stability...
High‐performance flexible lithium–oxygen (Li–O2) batteries with excellent safety and stability are urgently required due to the rapid development of flexible and wearable devices. Herein, based on an integrated solid‐state design by taking advantage of component‐interaction between poly(vinylidene fluoride‐co‐hexafluoropropylene) and nanofumed silica in polymer matrix, a stable quasi‐solid‐state electrolyte...
To keep pace with the increasing pursuit of portable and wearable electronics, it is urgent to develop advanced flexible power supplies. In this context, Zn‐ion batteries (ZIBs) have garnered increasing attention as favorable energy storage devices for flexible electronics, owing to the high capacity, low cost, abundant resources, high safety, and eco‐friendliness. Extensive efforts have been devoted...
Artificial skin devices are able to mimic the flexibility and sensory perception abilities of the skin. They have thus garnered attention in the biomedical field as potential skin replacements. This Review delves into issues pertaining to these skin‐deep devices. It first elaborates on the roles that these devices have to fulfill as skin replacements, and identify strategies that are used to achieve...
Hybrid Na‐ion capacitors (NICs) are receiving considerable interest because they combine the merits of both batteries and supercapacitors and because of the low‐cost of sodium resources. However, further large‐scale deployment of NICs is impeded by the sluggish diffusion of Na+ in the anode. To achieve rapid redox kinetics, herein the controlled fabrication of mesoporous orthorhombic‐Nb2O5 (T‐Nb2O...
Electronic eye cameras are receiving increasing interest due to their unique advantages such as wide field of view, low aberrations, and simple imaging optics compared to conventional planar focal plane arrays. However, the spectral sensing ranges of most electronic eyes are confined to the visible, which is limited by the energy gaps of the sensing materials and by fabrication obstacles. Here, a...
A novel two‐side‐activatable high‐performance surface‐enhanced Raman spectroscopy (SERS) substrate is developed based on the tape‐imprinting method. It features 3D full‐space‐distributed hot spots originating from the hierarchical lotus seedpod‐like silver arrays, which offer ultrasensitive, uniform, reproducible, and reliable quantitative measurements with an inherent internal standard. This excellent...
Ternary transition metal oxides (TMOs) are highly potential electrode materials for lithium ion batteries (LIBs) due to abundant defects and synergistic effects with various metal elements in a single structure. However, low electronic/ionic conductivity and severe volume change hamper their practical application for lithium storage. Herein, nanosheet‐assembled hollow single‐hole Ni–Co–Mn oxide (NHSNCM)...
