摘　　要：目的设计一种基于载人离心机训练实际需求的新型耳脉搏信号传感器。方法传感器采用透射式光电容积法原理,外形为耳夹式,以硅橡胶为外部包覆材料;内部元器件选用微型白炽灯泡作为光源,以硅光电池作为信号接收元件。考察了126名健康男性志愿者在不同载荷条件下的训练时耳脉搏信号质量,以及受试者主诉与耳脉搏信号变化的符合度。结果在低载荷(2. 5 G)被动训练和中载荷(5. 0G)、高载荷(9. 0 G)主动训练过程中,受试者的耳脉搏信号稳定,波形变化情况与受试者主诉总符合率为91. 5%。结论本研究设计的信号传感器能够在载人离心机训练载荷环境下正常使用,输出波形幅度变化与受试者是否到达耐力终点有较高的符合性。Objective To design a new ear-pulse signal sensor device based on the requirements of training in human centrifuge. Methods The sensor device was based on the principle of transmission photoelectric plethysmography and was an ear-clip type covered with silicon rubber. The micro incandescent light bulb was selected as the light source and silicon photovoltaic cell as the signal receiving element. Tests were carried out in126 healthy male volunteers with different Gz loads to validate the quality of the signal and the consistency between the subjects’ complaints and the signal changes. Results Both in the process of passive training with low Gz( 2. 5 G) and active training with medium Gz( 5. 0 G) or high Gz( 9. 0 G),the signals of the sensor device were stable. The consistency between subjects’ complaints and the signal changes was more than 91. 5%.Conclusion The new sensor device could effectively satisfy the requirements of human centrifuge training under+ Gz conditions,and the output signals were highly consistent with the subjects’ tolerance limit.
