Recent development in wearable sensors for healthcare applications

Abstract

Wearable sensors aid in diagnosing various diseases by using chemical, physical, and biological sensing technologies. They also make it possible to continuously and instantly monitor a patient's physiological state. Recently, the demand for sensors that track people's surroundings, fitness and health has increased. In the meantime, the production of flexible and wearable polymer sensors based on biocompatibility, biodegradability, environmentally friendly features and cost-effectiveness has created a significant evolution in the wearable sensor industry. In this review, the most recent researches conducted in the direction of the construction of wearable sensors in different fields including physical, optical, chemical, biochemical and the working mechanism of these sensors have been reviewed. Assisting researchers in selecting the most appropriate selective and sensitive sensor is a key objective of this review. In addition, the applications of these sensors were classified into different categories and discussed in fields such as health care and remote welfare. In general, improving personal health care and monitoring their performance using wearable electrochemical and biosensor technologies have a significant impact on people's daily lives. © 2025 Elsevier B.V.
