Herein， a pulse measurement system based on bent optical fibers was investigated. First， an optical fiber sensor head was designed according to the bending loss theory of the optical fiber. Then， the collected data were processed， and the feature points were extracted and analyzed. When the pulse signals for different people with different ages and genders were measured before and after exercise， the tidal wave disappeared after the exercise， and the frequency and amplitude of pulse obviously increased. The tidal wave， dicrotic wave peak， and dicrotic wave trough of middle-aged people were not as pronounced as those of young people. Women showed a significantly smaller pulse pressure difference than men. Experimental results showed that the pulse measurement system based on the bent optical fiber could reproduce the detailed parameters of the pulse signal and accurately measure the main wave， tidal wave， dicrotic wave peak， dicrotic wave trough， and other characteristic points. These properties are significant for developing digital pulse diagnosis technology.
