Truly form-factor-free industrially scalable system integration for electronic textile architectures with multifunctional fiber devices

Abstract

An integrated textile electronic system is reported here, enabling a truly free-form-factor system via textile manufacturing integration of fiber-based electronic components. Intelligent and smart systems require freedom of form factor, unrestricted design, and unlimited scale. Initial attempts to develop conductive fibers and textile electronics failed to achieve reliable integration and performance required for industrial-scale manufacturing of technical textiles by standard weaving technologies. Here, we present a textile electronic system with functional 1D devices including fiber photodetectors (F-PDs as an input device), fiber supercapacitors (F-SCs as an energy storage device), fiber field effect transistors (F-FETs as an electronic driving device), and fiber quantum dot light emitting diodes (F-QLEDs as an output device). As a proof of concept applicable to smart homes, a textile electronic system composed by multiple functional fiber components is demonstrated, enabling luminance modulation and letter indication depending on sunlight intensity.
