“…[92][93][94][95] In general, the nature-inspired materials in flexible devices can be mainly divided into two aspects: a) Nature-derived materials with impressive mechanical flexibility and functionality: These are from renewable and cost-effective materials in nature, benefitting sustainable development of both electronics and environment. [96][97][98] b) Natural structure or function inspired artificial materials or electronics: unique structures and functions in nature inspire the design of new materials and configurations with intriguing property and super performance. [99][100][101][102][103][104][105][106] The representative examples of nature-derived materials, natureinspired structures, and nature-inspired functions in flexible electronics are summarized in Figure 2.…”

The flourishing development of multifunctional flexible electronics cannot leave the beneficial role of nature, which provides continuous inspiration in their material, structural, and functional designs. During the evolution of flexible electronics, some originated from nature, some were even beyond nature, and others were implantable or biodegradable eventually to nature. Therefore, the relationship between flexible electronics and nature is undoubtedly vital since harmony between nature and technology evolution would promote the sustainable development. Herein, materials selection and functionality design for flexible electronics that are mostly inspired from nature are first introduced with certain functionality even beyond nature. Then, frontier advances on flexible electronics including the main individual components (i.e., energy (the power source) and the sensor (the electric load)) are presented from nature, beyond nature, and to nature with the aim of enlightening the harmonious relationship between the modern electronics technology and nature. Finally, critical issues in next-generation flexible electronics are discussed to provide possible solutions and new insights in prospective exploration directions.

“…Using this prestretching method, stretchable polymeric microelectrodes such as the polypyrrole (PPy) electrode were produced with high stretchability (≈100%) . Similar to ancient paper folding art, the origami and kirigami approach was proposed for stretchable electronics with advantages such as high throughput, large deformability, and comparable performance to rigid electronic . Unlike the island–bridge design, the origami and kirigami approach does not use elastomers and is compatible with well‐established manufacturing processes.…”

Living things rely on various physical, chemical, and biological interfaces, e.g., somatosensation, olfactory/gustatory perception, and nervous system response. They help organisms to perceive the world, adapt to their surroundings, and maintain internal and external balance. Interfacial information exchanges are complicated but efficient, delicate but precise, and multimodal but unisonous, which has driven researchers to study the science of such interfaces and develop techniques with potential applications in health monitoring, smart robotics, future wearable devices, and cyber physical/human systems. To understand better the issues in these interfaces, a cyber–physiochemical interface (CPI) that is capable of extracting biophysical and biochemical signals, and closely relating them to electronic, communication, and computing technology, to provide the core for aforementioned applications, is proposed. The scientific and technical progress in CPI is summarized, and the challenges to and strategies for building stable interfaces, including materials, sensor development, system integration, and data processing techniques are discussed. It is hoped that this will result in an unprecedented multi‐disciplinary network of scientific collaboration in CPI to explore much uncharted territory for progress, providing technical inspiration—to the development of the next‐generation personal healthcare technology, smart sports‐technology, adaptive prosthetics and augmentation of human capability, etc.

“…Based on the energy storage mechanism, supercapacitors can be classified into two classes: electric double-layer capacitors (EDLCs) and pseudocapacitors. Usually EDLCs involve porous, carbonaceous materials like graphene, heteroatom (N2,10 B,11 Fe,12 S13) doped graphene and carbon nanotubes while pseudocapacitors solely employ binary, ternary, or even quaternary metal oxides and hydroxides [1].The field of nanotechnology can be viewed as a pioneer in promoting the fabrication of novel supercapacitive materials with a large variety of potential applications [2]. The contact area of the electrode/electrolyte surface per unit mass can be significantly increased by reducing the dimensions to the nanoscale.…”

Graphene-metal frameworks have been extensively studied and developed as electrode materials for next generation energy storage materials. Their high surface area and easily transformable structure enhances its specific capacitance characteristics. In the present study, graphene oxide (GO) was synthesized using Hummers method. Zinc oxide and copper oxide nanoparticles were incorporated in to the GO matrix to form mixed metal oxides. GO, GO-CuO and GO-ZnO were characterized using UV-Visible, FTIR, FT Raman spectroscopy, SEM and XRD to confirm their effective formation. The surface of the glassy carbon electrode was modified by drop casting with the samples on its surface and its electrochemical properties were studied. Cyclic Voltammetry studies were conducted at various scan rates in different electrolytes (KCl, H 2 SO 4 and Na 2 SO 4) and the characteristic curves were observed to be asymmetric in nature. GO-CuO exhibits the highest specific capacitance of 790 F/g at 5 mV/s in KCl. The specific capacitance of the modified electrodes was also measured using the Chronopotentiometry technique. GO-CuO nanocomposites show a maximum specific capacitance of 800 F/g at 1 A/g. The nanocomposites showed enhanced electrochemical behaviour of the nanocomposites when compared to pure GO. The nanocomposites also showed good cycling stability. The superior performance of the GO-CuO and GO-ZnO nanocomposite electrode renders it as a promising material for supercapacitors applications.
