As the global trend of population ageing intensifies, the health management needs of the elderly are becoming increasingly urgent, while the existing pension system and medical resources are ill-equipped to cope with this realistic challenge. In this context, smart health wearables, as a major innovation in the field of health technology. integrate advanced technologies such as sensors, mobile technology and artificial intelligence to efficiently collect and analyze users' physiological data, provide real-time feedback on health conditions and provide early warnings, and help users realize self-health management. These products demonstrate considerable potential for application among the elderly population, offering efficient and convenient health management services that are expected to significantly enhance their quality of life and optimize the allocation of medical resources. In recent years, the rapid development of this field has triggered extensive research in the academic community. However, the majority of existing studies focus on technology development and application scenarios, and lack a systematic overview of the field and a comprehensive comparison of domestic and international studies. To address this gap, the study employed bibliometric methods to systematically review and evaluate the research conducted over the past decade on smart health wearables for the elderly, both domestically and internationally. The aim is to reveal the current research status, hotspots, and trends in this field, and to explore potential research directions, providing valuable insights for academic research, technological innovation, and practical applications. Using the CNKI and Web of Science core databases as data sources, the study selected relevant literature on elderly smart health wearables published between 2013 and 2023. A total of 339 domestic and 649 international papers were chosen, and the data were visualized using VOSviewer and CiteSpace software. First, descriptive statistical analysis was conducted on the annual publication volume, as well as the contributions of countries and institutions. Second, co-occurrence and clustering analyses of keywords were performed to identify research hotspots domestically and internationally. Additionally, keyword time-zone and burst detection were used to reveal the evolution of research frontiers. Finally, co-citation analysis was employed to present the foundational knowledge structure of international research and identify influential classic works. This study is the first to conduct a bibliometric analysis of research on elderly smart health wearables both domestically and internationally. This study has constructed knowledge maps providing a clear framework for the existing research in this field. The study reveals the current research status and trends in the field of smart health wearables for the elderly from four dimensions: spatiotemporal distribution, research hotspots, frontier evolution, and knowledge foundations. The results show that the USA and China dominate international research in this field, with particularly close academic collaboration between the two countries. Although domestic and international research have different focuses, domestic studies mainly concentrate on the integration of wearable technology and elderly care systems, while international research focuses more on technological innovation in health management and its practical applications, as well as elderly technology acceptance. Domestic research has evolved from product development and the optimization of elderly care systems to smart health management applications. Meanwhile, international research has shifted from technology development and system integration to in-depth exploration of elderly technology acceptance and adoption. Additionally, geriatric technology adoption assessment, health monitoring technology innovation, and smart health management applications form the foundational knowledge of this field. Future research should strengthen interdisciplinary collaboration between engineering and medical fields, so as to explore user experience and needs to optimize elderly-centered product design. Long-term efficacy validation is necessary to ensure the practical application of smart health wearables. These studies will drive the further development of smart health wearables for the elderly, and offer effective support in addressing the global health challenges posed by aging.
