Fig. 4: Design of smart textile display system from material to system level.

a List of F-devices integrated into the smart textile system, materials, device architecture, auxiliary parts, signal processing/coding, and F-LED visualising. Applications displaying on textile system: Real-time operation photos of b Six-signal strengths digitized depending on the distance between F-RF antenna and transmitter. c Programmed image initiated by UV irradiation on F-photodetector. d Real-time temperature monitoring by F-temperature sensor grasped by fingers. e Electrocardiography signal measured by F-biosensor module. f One of 30 IoT functions operated by F-touch sensor. g F-energy as a power supply to the switch of textile display.
