TECHNOLOGIES OF PORTABLE TRACKERS AND PRINCIPLES OF THEIR OPERATION FOR COLLECTING AND ANALYZING SLEEP BIOMARKERS

Maintaining accuracy in sleep quality is important for a deeper understanding of its impact on human health. The development of wearable technologies has become an integral part of the healthcare industry. These technologies provide a wide range of devices that collect data from various sensors and provide information about their users, including sleep. Modern devices, such as smartwatches or fitness bracelets, can detect various bio-signals, such as heart rate and heart rate changes, skin temperature and skin resistance, which are used to calculate data on the consumer's activity and health. These devices operate around the clock, collecting a large amount of data that can provide new opportunities for analyzing, maintaining and improving health. The article aims to reveal the methods and principles of modern sleep trackers, including algorithms for analyzing the consumer's health status, the results of which can be used in clinical trials. Despite the broad prospects of technologies for sleep analysis, it is advisable to approach their use with caution, given the benefits and possible risks they pose to research in the field of sleep and its impact on health.
