The wrist-pulse is a kind of blood flowing and vibration signals, from which a lot of physiological and pathological status of patients are deduced according to traditional Chinese medicine theories.In this paper, an optical fiber pulse-diagnostic equipment based FBG sensor array is introduced.Optical fiber sensor structure and principle are described in detail.Sensor array is set to be 2 x 3 to fit clinic trail.Sensitivity of the optic fiber wrist-pulse sensor reaches 0.05% FS and the range reaches 50kPa.Some eases of clinical experiment are demonstrated which collected from hospital recently.
