We constructed a robust and low-priced finger pulse sensor from a singing greeting card beeper. The beeper outputs the plethysmographic signal, which is indistinguishable from that of commercial grade sensors. The sensor can be used in school for a number of experiments in human cardiovascular physiology.
我们用一个会唱歌的贺卡蜂鸣器制作了一个坚固且价格低廉的指脉搏动传感器。这个蜂鸣器输出的体积描记信号与商用级传感器的信号无法区分。该传感器可以在学校中用于进行许多人类心血管生理学实验。
