Increasing the polymer insulation performance in high-voltage environments is crucial for protecting large-capacity and integrated power equipment and ensuring the safe and stable operation of electrical devices. Here, we discuss the phenomena and the underlying mechanisms of bulk breakdown and surface flashover that lead to insulation failure in polymers and present relative strategies to increasing the performance of the insulating materials. We analyse the challenges faced by polymeric insulating materials in various extreme environments and the strategies to address them. Finally, we identify key challenges and highlight future directions and opportunities for the development of reliable polymeric insulating materials.

The evolution of device structures has led to the iterative development of display technology from rigid bulk to flexible films. Recently, next-generation displays have woven electroluminescent units directly into polymer composite fibres to form textile displays. Such displays are flexible and breathable, like clothing, suggesting applications such as wearables and smart textiles. In particular, they would allow users to interact with electronic devices by touching the clothing. This Perspective provides a summary of the evolution of textile displays. We then discuss recent achievements in the field, including applications of textile displays, advances in active materials, designs of interfaces between the active layer and fibre electrodes, developments in display modules, and integration of textile displays with multiple electronic functions. Finally, we highlight the potential challenges of textile displays for practical applications and suggesting future research directions in this exciting field. This Perspective highlights the design concepts, fabrication strategies and recent achievements in textile displays, including promising applications, advances in luminescent materials, design of device interfaces, development of display modules, integration of displaying systems and the remaining challenges.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":"1 7","pages":"466-477"},"PeriodicalIF":0.0,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141501434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the various alternatives, wind is one of the most abundant resources. Traditionally, wind energy has been harvested to produce electrical energy using various types of wind turbines, including onshore or offshore wind turbines, horizontal or vertical axis wind turbines and micro-wind turbines; or, less traditionally, using wind pumps, or windmills, on sailing boats, and through some sports activities (such as kiteboarding, windsurfing and kitesurfing). In this context, wind energy harvesting using triboelectric nanogenerators (TENGs) has unique characteristics able to challenge the existing wind energy harvesting technologies. Wind-driven TENGs are in fact characterized by simple structures, reduced size and weight, easy installation, flexibility and low-cost operation. Here, starting from a detailed comparison with conventional wind turbine systems, we introduce the technological advancement of wind-driven TENGs. Device structures, materials, fabrication processes and performance characteristics in terms of costs and applications are outlined. Open issues and challenges to be addressed towards the development and industrialization of commercial products are also presented. Wind-driven triboelectric nanogenerators have the potential to revolutionize wind energy harvesting technologies. This Review analyses developments, costs and challenges of wind-driven triboelectric nanogenerators and evaluates research directions towards industrial applications.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":"1 7","pages":"453-465"},"PeriodicalIF":0.0,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141501435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the proliferation of computationally intensive and highly complex GenAI models poses substantial challenges to servers and central network capacities. To effectively permeate various facets of our lives, GenAI heavily relies on mobile edge computing. In this Perspective article, we first introduce GenAI applications on edge devices highlighting its potential capacity to revolutionize our everyday life. We then outline the challenges associated with deploying GenAI on edge devices and present possible solutions to effectively address these obstacles. Finally, we introduce an intelligent mobile edge computing paradigm able to reduce response latency, improve efficiency, strengthen security and privacy preservation and conserve energy, opening the way to a sustainable and efficient application of the different GenAI models. The application of generative artificial intelligence to mobile devices has the potential to enable integrated, personalized, contextually aware experiences. However, the computational energy demand is challenging.

Since 1994, tremendous progress has been made in improving the external quantum efficiency and lifetimes of QD-LEDs, and there has been growing understanding of the operational and degradation mechanisms. However, there are still critical problems that remain to be clarified, such as the origin of positive ageing and the role of zinc oxide nanoparticles in achieving high performance. In this Review, we analyse the key factors influencing voltage, internal quantum and photon out-coupling efficiencies of QD-LEDs. We point out the issues related to cadmium-free quantum dots and short-lifetime blue QD-LEDs. Finally, we clarify the challenges and summarize the latest progress in commercializing QD-LEDs. Quantum dot light-emitting diodes (QD-LEDs) are attractive for display and lighting applications. Precise understanding of their operational and degradation mechanisms will greatly promote the commercialization of this technology.
