Sensory Fiber-Based Electronic Device as Intelligent and Natural User Interface

A natural user interface (NUI) with ample information perception capability is a crucial element for the next-generation human–machine interaction and the development of the intelligent era. However, significant challenges remain to be solved in developing intelligent and natural interfaces with satisfactory smart sensing performance. Here, we report an NUI based on an intelligent fabric bracelet empowered with wide-range pressure detectability, enabling invisible and efficient human–machine interaction. The wide-range pressure-sensing ability of the fiber-based pressure sensor can be attributed to the coupling mechanism of contact resistance change and quantum tunneling effect. The fiber-based sensor array is then integrated with a miniaturized wireless flexible printed circuit board, forming an intelligent and compact fabric bracelet system for natural interactive applications in wireless smart home control and virtual reality. It is envisioned that the NUI based on the pressure-sensitive and intelligent fabric bracelet will significantly contribute to the development of next-generation NUIs for more diversified control and interactive applications.
