The invention discloses a flexible wearable
optical fiber sensor and a human dynamic
whole body distributed monitoring method. A human dynamic
whole body monitoring system comprises a demodulator, a host computer, and a plurality of the flexible wearable
optical fiber sensors, wherein the flexible wearable
optical fiber sensor is composed of a flexible bending optical
fiber module, a first
fiber Bragg
grating, a second
fiber Bragg
grating and a
fiber Bragg grating protection structure. The
fiber Bragg grating wavelength division
multiplexing technology is used, the plurality of the flexible wearable optical fiber sensors are connected in series and fixed to a user's body through Velcro and elastic bands, and the user's movement status, including a joint bending angle, a
muscle stretching amount, a
respiration rate and other physiological parameters, is monitored. The recognition of stretching and bending degrees is realized by detecting the change of the
light intensity corresponding to an
fiber Bragg grating spectral
signal center
wavelength, physiological parameters such as a joint bending angle, a
muscle stretching amount and a
respiration rate are monitored in real time when the
human body is active, high precision and sensitivity are achieved, and the flexible wearable optical
fiber sensor has a simple structure, and can be worn freely without affecting the user's movementfreedom degree.
