Abstract

Wearable bioelectronic and health monitoring devices have transformed personalized medicine by allowing continuous, real-time monitoring of physiological signals. Flexible, biocompatible, a highly sensitive materials are essential to further develop these technologies. MXenes, a group of twodimensional (2D) transition metal carbides and nitrides, have gained much attention because of their high electrical conductivity, mechanical flexibility, hydrophilicity and biocompatibility. These characteristics place MXenes as potential next-generation wearable sensors and bioelectronic interfaces that can detect a broad spectrum of physiological parameters with high accuracy and comfort. This brief review highlights recent advancements in the use of MXenes towards wearable health monitoring and bioelectronic devices with regard to their material properties, sensing mechanisms, biocompatibility, and challenges for practical implementation.
