This paper presents a RBC fatigue evaluation. The fatigue state is defined by the times of reciprocated mechanical stress when the extensibility and the recoverability states conclude to the same value. Our challenge is how to construct a system capable of achieving stable and accurate control of RBC in a microchannel. By utilizing a new developed syringe pump and an online high-speed camera, we could achieve continuously observing the length of RBC over 1000 times reciprocated mechanical stress. Experimental study on RBCs were conducted with the developed system. Through the experiments, we found that the fatigue state of each cell has a fairly well correlation with its own extensibility, and it implies that a cell with better extensibility could sustain more reciprocated stress.
