Because of the widespread use of wearable devices in everyday life, there is a
growing demand to acquire good-quality data on as many vital functions as
possible for better and faster diagnosis and treatment implementation. This
review focuses on the recent advancements and progress of wearable devices’
technology and their possible implementation for improving users’ health,
mainly in cardiology, sleep, and stress. In cardiology, there is a focus on creating
a device that records good-quality electrocardiograms and can diagnose more
than atrial fibrillation. A growing number of studies also focus on finding the
best way of estimating blood pressure using wearable devices. Acquiring reliable
data on experienced stress can help users to manage it and professionals to
alleviate it, resulting in better compliance. Sleep monitoring can help raise
awareness, prevent many diseases, and improve users’ overall health. In
conclusion, there are constant attempts for improving wearable devices to better
monitor vital signs in everyday life. Most wearable devices lack validation in
their accuracy for detecting, tracking, and analyzing some vital signs. With their
ever-growing popularity, it is of utmost importance to ensure the data they
gather is of good quality.
