The Internet of Things (IoT) is expanding rapidly and can potentially be a huge data source. This study aimed to close the knowledge gap about possible IoT applications in health care. English-language academic publications from the Web of Science (WoS) were used for the present study. Bibliometric networks were used to analyze pertinent publications to examine the connections between authors, nations, and affiliations. Papers on digital health care have been published in more than 1195 sources, among which the most popular was the Journal of Medical Internet Research. Six top institutions were from the Netherlands, making the Vrije Universiteit Amsterdam the most productive institution after Australia and England. This study provides an overview of IoT-related research conducted in digital health care, helping academic researchers, policymakers, and practitioners to better understand the development of digital health care research.
