The growing body of research on Wireless Sensor Networks (WSNs) has given medical gadgets a whole new meaning. Advances in microcontroller technology are mostly to blame for this. The relevance of WSNs in fields including health, psychology, fire prevention, security, and even the military is attributed to its status as one of the century's great technological advancements. The capacity to follow, monitor, research, comprehend, and respond to any specific occurrence or incident is this technology's key benefit. A wireless health system's main goal is to provide trustworthy data as quickly as possible. The extensive body of work on Wireless Biomedical Sensor Networks (WBSNs) research is surveyed in this review, along with examples from theoretical and empirical literature, as well as experimental and non-experimental studies. In order to provide a coherent and accessible overview of WBSNs, the review includes a broad range of objectives, including the definition of ideas, a study of theories, failures, and less favorable elements. Some of these systems are now on the market, while others are still being researched. This study also seeks to determine the WSN attributes relevant to healthcare.
