英文摘要： Smart clothing is the combination production of information, textile and other disciplines which can monitor the changes of external environment or internal state of body and has the advantages of portability and real-time monitoring etc. Fiber grating is the ideal sensing element for smart clothing because of the small size, high sensitivity, anti-electromagnetic interference and compatibility with yarn. The research on blood pressure measurement and smart clothing based on fiber grating pulse wave has not been reported at home and abroad. This project intends to study fiber grating pulse wave detection theory and methods, reveal fiber grating fabric sensing mechanism, and establish pulse wave sensing model. In order to implement all-fiber wavelength demodulation, fiber grating wavelength demodulation method based on photonic crystal fiber in-line M-Z interferometer is presented. Blood pressure measurement method and signal processing algorithm based on multi-pulse characteristics parameters are proposed to improve the accuracy of measurement through revealing the relationship between pulse characteristics parameters and blood pressure, and establishing a blood pressure calculating model. The method of integrating the fiber grating sensor and demodulation optical circuit into clothing is designed. The correctne
