Intercalation Engineering of 2D Materials at Macroscale for Smart Human–Machine Interface and Double‐Layer to Faradaic Charge Storage for Ions Separation

2D materials have attracted considerable attention in the past decade for their superlative physical properties. Lightweight foam from can reduce use of raw materials, save energy processing material and downregulate carbon emission. Self-assembling graphene nanosheets results 3D porous lightweight resembling hydrogels, aerogels, xerogels. Hierarchical architecture provides an uninterrupted path to electrons phonon transport conforms eligibility developing sensor, storage, conversion devices. Artificial intelligence (AI) originates human–machine interaction physiological signal reception which requires a large sensing range that illustrates healthcare surveillance with wearable Spongy architectures flexibility reversible compressibility act as good candidate pressure wide real-time human health monitoring systems by using artificial intelligence. In this review, new perspective emerging (such MXene, borophene) along investigation structure is demonstrated. Electrosorption salt-ions under electrode are reviewed context electrochemical stability recycling ability, efficiency adsorption-desorption. Beyond these, remaining challenges depicted 2D-materials interest sensors flexible supercapacitors promising research directions.
