Abstract
These days, wearable biosensors are a very valuable tool for tracking the
start of various acute and chronic diseases. Wearable biosensors (WBSs) are small,
electrical devices that coordinate and collect sensations into the human body and can be
present in the form of tattoos, gloves, clothing and inserts. WBSs are a flexible and
practical tool for use in the healthcare industry, thanks to their ability to detect
information, record it and estimate it accurately. WBSs help patients and doctors to
communicate in both directions. It is simple to do painless evaluations of bodily fluids
using various biochemical markers such as spit, sweat, skin, and tears. As the
continuous state of capabilities of wearable and adaptable sensors continues to
advance, the creation of new wearable gadgets that can fill the gap and handle the
advantage of human well-being checking and clinical application is advancing. Blood
is still the most crucial bio-liquid for assessing a person’s health, even though more
attention has been paid to other bodily fluids that are naturally secreted and severe
functions that are similar to those of blood. There has been a lot of interest in the
capacity of compact biosensing devices to identify the analyte in bio-liquids for the
early detection of human well-being.
