MXene: A 2-Dimensional Material for Wearable and Flexible Electronics

The unique properties of hydrogels, including their capacity to stretch, adhere to themselves, be transparent, and be compatible with living organisms, have attracted significant attention in recent times. Flexible electronics, human-machine interfaces, sensors, actuators, and other similar technologies can all derive advantages from their capacity to transmit electrical signals. MXene is a newly found two-dimensional nanomaterial that exhibits potential as a wearable sensor because of its negative charge, ability to attract water molecules, compatibility with living organisms, large surface area per unit mass, ease of modifying its properties, and excellent ability to conduct electricity like a metal. Despite the fragility of MXene-based applications, the manufacturing process of MXene into hydrogels has demonstrated a significant enhancement in their endurance. Although there has been a lot of research into using MXene-based composites in sensors, research into using MXene-based hydrogels in wearable electronics and how to prepare them is still in its infancy. Condensed and reviewed below are the many applications, manufacturing processes, and design considerations for MXene hydrogels in wearable and flexible electronics. Its goal is to support the advancement of MXene hydrogel sensors.
