Special Issue Information
Dear Colleagues,
Rapid technological development in modern society has encouraged the demand for flexible and portable devices, such as wearable sensors which can be integrated directly with the body for healthcare monitoring to provide clinically relevant data vital to maintain physical fitness, or miniaturized sensor tags for maintaining food quality, safety, and environment. Such sensors hold great promise as they possess potential for remote monitoring of the subjects with chronic conditions in the home, community, or environment.
These emerging flexible electronics require a large spectrum of flexible power sources, including flexible batteries and supercapacitors. Among them, flexible supercapacitors are preferred in several situations due to their exceptional charge speeds, ability to release large currents, and outstanding cycle lives. In addition to the standard requirements for supercapacitors, mechanical robustness in terms of stretching or twisting reliability, accompanied by high safety, is paramount for the flexible capacitive devices. Such high-performance flexible supercapacitors can power the wide range of sensors.
In order to improve the sensing, electrochemical, and mechanical performances of such flexible devices, a proper choice of active materials and device architectures is critical. A significant volume of recent research on flexible devices has been broadly focused on carbonaceous materials. Among them, the use of carbon nanotubes and graphene-based nanomaterials in high-performance sensing and energy storage is one of the most promising avenues to develop futuristic devices.
The scope of this Special Issue is to bring together current developments in flexible sensors and flexible supercapacitors with an emphasis on flexible active platforms enabled by carbon nanotubes and graphene. The scope also includes fabrication strategies of flexible/stretchable sensors as well as supercapacitors, new device design, integration, and their implementations in different applications. The list of topics this Special Issue covers incudes, but is not limited to, the following:- Flexible/stretchable sensors;
- Flexible/stretchable supercapacitors;
- Carbon nanotubes;
- Graphene and related materials;
- Synthesis techniques for flexible sensors/supercapacitors;
- Engineering strategies for flexible sensors/supercapacitors;
- Micro-patterned (MEMS) based flexible sensors/supercapacitors;
- Carbon nanotubes as a flexible scaffold for sensing probe/pseudocapacitive materials;
- Graphene as a flexible scaffold for sensing probe/pseudocapacitive materials;
- Self-powered sensors coupled with supercapacitors;
- Hybrid forms—graphene/carbon nanotubes with functionalization/doping;
- The state of the art and future prospects: problems and possible solutions.
