Abstract: 

Fiber-based optoelectronic technology is a new and cutting-edge technology developed in the past two decades. It is the result of infiltration and fusion of chemistry, physics, materials engineering, electronic engineering, optoelectronic engineering and textile engineering. The research object is optoelectronic fiber and its aggregate devices with sensing, actuation, communication, memory, self-adaptive, self-repairing, self-power and learning functions, which can perform the functions in a preprogramed manner. There are several ways to form fiber-based optoelectronic devices and systems. The fiber-based optoelectronic devices and systems formed by the combination of functional materials and fibers have many characteristics, such as flexibility, large deformation, light weight, large area, fashionable, comfort, and do not affect the activities and functions of people or machines, allowing long-term real time use. It has great potential advantages in engineering man-machine interfaces, large-area optoelectronic devices and systems, transportation, security, smart Internet of Things, smart cities, healthcare, wearable devices and systems. At the same time, safe green functional materials are employed, which can be processed at room temperature or under low temperature and non-vacuum conditions with mature machinery and processing technology. Multiphysics processes are involved in the manufacture and use of fiber-based optoelectronic devices, which typically involve large macroscopic deformation, mesoscopic fiber complexity, multiphase materials (including solids and gases), porous, multi-interface and so on. The unique structure and characteristics require the development of new characterization and analytical methods. In this talk, the related scientific problems and some solutions are proposed and discussed for the materials and structures of fiber-based and fiber assemblies (textile structure) optoelectronic devices, and their optical, electrical, thermal, mechanical properties and characterization.
