Concurrently, the evolution of VR visors in terms of wearability, quality of the visual immersion and immediateness of bare-hand interaction poses both opportunities and challenges for haptic systems, which must match these visors in usability, hand-tracking compliance and quality of experience. Designing haptic devices involves trade-offs between the dimensions and quality of feedback, often falling short of the richness and complexity of natural haptic sensations. Recent studies have explored various actuating methods and haptic prototypes to enhance the wearability and feedback richness of haptic devices. Notably, the development of soft interfaces actuated by diverse principles has emerged as a key trend. Moreover, beyond simulating physical interaction, haptic technologies can provide high-level information for various applications, including posture correction, navigation and remote control of humanoid robots. In this Review, we provide an overview of wearable haptics for VR applications, introducing principles of haptic rendering and the relationship between stimulus modalities and actuating solutions. We discuss emerging actuating methods and wearable device designs, examining their experimental applications in innovative scenarios of VR and beyond. This Review provides an overview of haptic perception principles and rendering strategies developed for wearable haptics solutions. The Review then revises the scientific literature regarding emerging actuators and device prototypes, and their applications in innovative scenarios focused on, but not limited to, virtual reality (VR).","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142431089","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}

Innovative technologies have led to cost-effective manufacturing. Lower launch costs have encouraged private ventures to deploy broadband LEO networks targeting market opportunities such as internet services for remote or under-served areas, mobile connectivity, governmental services and communication services for emergency response and disaster relief. Ubiquitous coverage and resilience are key characteristics of space-based communications. However, LEO satellite operators face several technical challenges, which need to be addressed to unleash the full potential of this promising technology. Here, we describe the developments in the field of LEO broadband constellations and discuss the challenges to establish a LEO-based extension to current 5G and coming 6G cellular networks. We also present the advancements that are, from the beginning of the 2020s, empowering LEO constellations to become a fundamental complement to, and be integrated with, terrestrial-based communication networks. Finally, we introduce the activities related to standardization, experimental validations and demonstrations and present our own vision on the potential of the technology to transform the space-based connectivity. Low-Earth orbit constellations and their potential to connect the unconnected are at the forefront of the new space era. This work provides an overview of the low-Earth orbit broadband communications and their integration with 5G and 6G cellular networks.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215484","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}

As a complementary technology, wide bandgap semiconductors, including GaN and SiC, have attracted great attention owing to their unique features of high carrier mobility and high breakdown voltages. However, there are still limitations for widespread applications of wide bandgap semiconductors including scalability, high production cost and thermal management. To overcome these barriers, remote epitaxy and 2D layer transfer technology have been introduced and are in the process of being industrialized to produce single-crystalline semiconductor-based freestanding membranes. In this Perspective, we present the status and challenges for manufacturing GaN and SiC membranes based on remote epitaxy technology that offers significant advantages via wafer reuse and high-quality freestanding epilayer production. We also discuss how industrialization of advanced membrane technology can benefit numerous applications, including heterogeneously integrated circuits, power and radiofrequency systems. This Perspective discusses the status and challenges of remote epitaxy technology towards industrialization of wide bandgap semiconductors for the future electronics.","PeriodicalId":501701,"journal":{"name":"Nature Reviews Electrical Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215486","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}
