This book provides an interesting snapshot of new research within the fields of flexible and soft devices which use porous carbon-based materials. The increase in demand for soft and flexible electronics, electrochemical energy storage/conversion systems, piezoresistive pressure sensors has promoted the development of new strategies for the synthesis and integration of nanoporous carbon (NPC) into flexible and soft polymers and inorganic textures. The structural properties of such NPC materials combined with their mechanical, conductive and catalytic properties, show promising results for the technology they are designed for, which can be useful solutions in many other disciplines. An in-depth discussion of the use of NPC materials in different energy devices is provided in every chapter, while at the same time the knowledge of the reader on the various applications where these materials can be used will be broadened. This book sheds new light on nanoporous carbon-based materials and will be of great interest to graduate students and professionals working in this field.
