Wearable microneedle-integrated sensors for household health monitoring

Wearable biosensors, which aim at providing continuous, real-time physiological information via monitoring and screening biomarkers in human body, are receiving increasing attention among various fields including disease treatment, diagnosis and self-health management. The ongoing development in this realm starves for the exploration of fully-integrated, non-invasive devices. In this paper, we review the latest achievements with breakthrough significance on the wearable biosensors. We start with the classification of different types of wearable electronic devices and analyze their characteristics and application values. Subsequently, we introduce a fully-integrated microneedle-based sensor and provide an in-depth look at its structure, subcomponents and in vivo performances. Finally, we put forward critical commentaries and clarify the direction of future researches.
