MXenes for Sensors

Active intercommunication between two different objects, whether it is person-to-person, person-to-robot, or person-to-environment, all begins with obtaining necessary information at the interface through sensing activities. Such information can be of various forms, being either mechanical forces such as pressure or strain, chemical interactions from gases or humidity, or various other physical and optical interactions. In order to obtain accurate information and properly respond to the surrounding environment, the precise and sensitive sensing is of paramount importance. The choice of material and engineering its structure play a large role in achieving this goal, due to the large variation between materials’ properties. Here, we will discuss the technical requirements in fabricating high-performance sensors and introduce several materials and their properties that have been utilized as sensing channels. Moreover, we will discuss the merits of MXenes over other materials and their potential to be used in various types of sensors.
