Advanced Carbon for Flexible and Wearable Electronics

Abstract

Flexible and wearable electronics are attracting wide attention due to their potential applications in wearable human health monitoring and care systems. Carbon materials have combined superiorities such as good electrical conductivity, intrinsic and structural flexibility, light weight, high chemical and thermal stability, ease of chemical functionalization, as well as potential mass production, enabling them to be promising candidate materials for flexible and wearable electronics. Consequently, great efforts are devoted to the controlled fabrication of carbon materials with rationally designed structures for applications in next‐generation electronics. Herein, the latest advances in the rational design and controlled fabrication of carbon materials toward applications in flexible and wearable electronics are reviewed. Various carbon materials (carbon nanotubes, graphene, natural‐biomaterial‐derived carbon, etc.) with controlled micro/nanostructures and designed macroscopic morphologies for high‐performance flexible electronics are introduced. The fabrication strategies, working mechanism, performance, and applications of carbon‐based flexible devices are reviewed and discussed, including strain/pressure sensors, temperature/humidity sensors, electrochemical sensors, flexible conductive electrodes/wires, and flexible power devices. Furthermore, the integration of multiple devices toward multifunctional wearable systems is briefly reviewed. Finally, the existing challenges and future opportunities in this field are summarized.

Customization of Conductive Elastomer Based on PVA/PEI for Stretchable Sensors

“…However, these methods show limitations in the next generation electronics, due to insufficient stretchability and sensitivity. Because of this, synthetical conductive elastomers with good stretchability and robustness have been intensely studied recently …”

All‐Printed MnHCF‐MnOx‐Based High‐Performance Flexible Supercapacitors

“…Flexible and wearable electronic devices have aroused great attention and may lead to the next revolution in electronics, such as transistors, electronic garments, sensors, etc. [ 1–5 ] Therefore, it is essential to develop renewable electric energy to meet the growing demands for flexibility and miniaturization of electronics. [ 6 ] Supercapacitors, also known as electrochemical capacitors with long life and high power density, can effectively balance the superiorities of batteries and conventional capacitors.…”

Flexible Piezoelectric Nanofibers/Polydimethylsiloxane‐Based Pressure Sensor for Self‐Powered Human Motion Monitoring

“…With additional chemical modification, flexible sensors could simultaneously sense different environmental parameters, such as pressure, temperature, and humidity, which are crucial for health monitoring. Wearable electromechanical sensors, such as pressure sensors, which can generate an electric charge in response to applied mechanical stress, have attracted tremendous attention due to their potential applications in human motion monitoring …”
