A Review and Survey of Medical Service Devices Based on Internet of Things Technologies

The integration of the Internet of Things (IoT) into the healthcare ecosystem has precipitated a paradigm shift in patient treatment trajectories. By facilitating rapid and highly reliable service delivery, IoT has fundamentally revamped the healthcare landscape. Current research indicates that the proliferation of sensor-based medical devices is continuously enhancing the reliability and efficiency of therapeutic processes. Driven by rapid advancements in communication technologies, the Internet of Medical Things (IoMT) has assumed a pivotal role in the digital transformation of the industry. However, this evolution is accompanied by multifaceted challenges, including the need for lightweight hardware, ensuring data and model explainability, and addressing critical security and privacy concerns. To fully leverage IoMT’s potential, it is imperative to focus on optimizing algorithms for minimal power consumption, developing novel explainable AI models, and ensuring resilience against security threats. This paper presents a comprehensive review of IoMT, detailing the expansion of smart healthcare systems, diverse applications, and core components. Furthermore, it provides a critical analysis of related works to highlight existing gaps and future directions in medical IoT.
