Carbon materials, including carbon nanotubes, graphene, and carbon fibers, have been widely used in the development of flexible and wearable electronics due to their outstanding properties such as high electrical conductivity, excellent mechanical strength, and flexibility. In this section, we will review the latest advances in advanced carbon materials in flexible and wearable electronics and their potential applications.
Carbon Nanotubes
Carbon nanotubes (CNTs) are cylindrical structures made of carbon atoms arranged in a hexagonal lattice. They have exceptional electrical and mechanical properties, making them ideal for use in flexible and wearable electronic devices. CNTs can be used as conductive fillers in flexible and stretchable sensors, enabling the detection of various physical and chemical stimuli such as pressure, temperature, and humidity. They can also be used as electrodes in energy storage devices such as supercapacitors and batteries, providing high power and energy densities.
Graphene
Graphene is a two-dimensional material made of a single layer of carbon atoms arranged in a hexagonal lattice. It possesses remarkable electrical, mechanical, and thermal properties, making it one of the most promising materials for flexible and wearable electronics. Graphene-based materials have been extensively used as conductive electrodes, sensors, and energy storage devices due to their excellent electrical conductivity, high specific surface area, and superior mechanical strength.
Carbon Fibers
Carbon fibers are made of carbon atoms bonded together in a crystalline structure, providing excellent mechanical and electrical properties. They have been widely used in the development of flexible and wearable electronic devices due to their lightweight, high tensile strength, and low coefficient of thermal expansion. Carbon fibers can be used as conductive fillers in stretchable sensors, providing high sensitivity and reliability. They can also be used as substrates in flexible and stretchable electronics, enabling the integration of electronic components on flexible and wearable platforms.
