Design, Assembly, and Fabrication of Two-Dimensional Nanomaterials into Functional Biomimetic Device Systems

Abstract

Diverse functioning biosystems in nature have inspired us and offered unique opportunities in developing novel concepts as well as new class of materials and devices. The design of bioinspired functional materials with tailored properties for actuation, sensing, electronics, and communication has enabled synthetic devices to mimic natural behavior. Among which, artificial muscle and electronic skin that enable to sense and respond to various environmental stimuli in a human-like way have been widely recognized as a significant step toward robotics applications. Polymer materials have previously been dominant in fabricating such functional biomimetic devices owing to their soft nature. However, lacking multifunctionality, handling difficulty, and other setbacks have limited their practical applications. Recently, versatile and highperformance two-dimensional (2D) materials such as graphene and its derivatives have been studied and proven as promising alternatives in this area. In this chapter, we highlight the recent efforts on fabrication and assembly of 2D nanomaterials into functional biomimetic systems. We discuss the structure-function relationships for the development of 2D materials-based biomimetic devices, their tailoring property features, and their variety of applications. We start with a brief introduction of artificial functional biomimetic materials and devices, then summarize some key 2D materialsbased systems, including their fabrication, properties, advantages and demonstrations, and finally present concluding remarks and outlook.

Water soluble flexible and wearable electronic devices: a review

“…In recent years, two-dimensional (2D) materials have attracted much attention owing to their excellent electronic, optoelectronic, electrical, and mechanical properties [51][52][53]. Even though these materials are water insoluble in nature, well studied 2D materials such as MoS 2 , Black Phosphorous, and MXene were recently utilized in flexible transient electronics [54][55][56].…”

Sublimation of MXene/camphor device: a study on self – destructive dry transiency

“…It is a well-known fact that 2D materials are an ideal choice for developing next-generation sensors. 19,20 MXenes are transition metal carbides or nitrides and the fastest growing materials among other 2D materials in recent years 21 . Their excellent thermal stability, wide interlayer spacing, hydrophilic nature, and easily tunable structure make it a valuable 2D material, which is not possible with other inorganic 2D materials 21 .…”
