Self-supported Materials for Flexible/Stretchable Sensors

Abstract

There is an increasing demand on the fabrication of robust, flexible, cost-effective, and eco-friendly self-supporting materials, such as yarns, fibers, papers-like, films, and monoliths, etc., due to their promising applications in flexible sensing fields. With the unique structure and outstanding properties, various functional materials with zero-dimensional, one-dimensional, and two-dimensional structures have been employed as promising building blocks for the assembly of self-supporting materials. In this chapter, the type, key parameter, and working principles of sensors are presented. Meanwhile, we summarize the sensing properties of different self-supporting materials through detailed cases. In addition, the challenges and opportunities of current sensors based on self-supporting materials are briefly discussed.
