ABSTRACT
A sensor is a device that detects or measures a physical property and then records, indicates, or responds to it in some way. Internet of Things (IoT) and wearable technologies have the potential to provide novel solutions to healthcare issues. Wearable sensors are electronic gadgets that consumers can wear to improve their personal experience by gathering health and fitness data. Wearable devices are also used to keep track of patients and diagnose diseases. Our goal is to provide an overview of recent advancements in the field of wearable sensors in order to summarise recent breakthroughs in this field. The focus of this chapter will be on wearable technology that can extract data from the body without the need for a sensor to be implanted. The fundamental goal of wearable technology and sensor development is to enable the generation of rich data sets that will allow health providers to make more individualised health decisions. In this study, we built wearable technology applications in healthcare for illness prevention and maintenance, such as weight control and physical activity monitoring. Current health monitoring systems must meet a number of criteria, including portability, low battery consumption, and ease of use. It is now possible to construct such systems and devices thanks to rapid advancements in technologies such as wireless, embedded, nanotechnology, and so on. In this research, we conducted a survey of several sorts of wireless standards, types of sensors utilised, and some of the most modern approaches in the field of health monitoring.
