Wearable electrochemical sensors for noninvasive monitoring of health-a perspective

Global problems today such as aging society and rising health costs have made preventive care and health monitoring increasingly important, so research on wearable electrochemical sensors for noninvasive monitoring of health has become very popular during the past several years. But the new technologies cannot be some dues ex machine who wrought changes overnight. Problems about fundamentals of electrochemistry under wearable conditions, software algorithms to treat signal artifacts in the real wearable detection, reliable sensors for prolonged wearable sensing in body fluid, platforms for tests of newly developed sensors, validation of test results, reproducible and standardized sampling methods, as well as clinical significance of wearable testing data still require to be addressed. The short review is not to include all important works recently published or reach any conclusion but to focus on the challenges as well as some of the promising approaches that help to overcome these challenges.
