MXene wearables: properties, fabrication strategies, sensing mechanism and applications

Abstract

The current pandemic has forced the healthcare system into a transformation where the patients are required to be continuously monitored without the need for hospitalization. The advances in wearable sensors with their ability to sense various body parameters precisely have helped in accelerating the personalized healthcare revolution. The selection of sensing material and its properties lay the foundation for designing flexible sensors and carrying out reliable measurements. Sensing materials for wearable applications, in general, are expected to be flexible, biocompatible, electrically conducting, electrochemically active, and of low cost. Ti₃C₂–MXene is a new two-dimensional transition metal carbide that belongs to the family of MXenes, which meets many of the material requirements for biochemical sensing applications. In the present work, we discuss the properties of Ti₃C₂–MXene in detail and analyze its potential in the development of wearable biosensors. A review of recent developments in this rapidly developing field and suggestions for future research directions are presented.
