摘　　要：研究了基于集成心跳探测芯片的心跳测试仪,介绍了其组成部分,即反射式红外传感器,单片机和LED显示器。该研究主要是根据人体组织半透明度随着心脏的搏动改变这个原理(即当血液送到人体组织时,组织的半透明度减小;当血液流回心脏,组织的半透明度增大),由红外传感器探测这一变化,通过专用集成电路将信号放大并利用,从而获得心跳的频率。Studies heart rate testers based on integration heartbeat detection chip and introduces other components of the testers such as reflective infrared sensor, single-chip and LED display. The study is mainly based on the principle which the semi-transparency of human tissue changes as the heart throbs. （that is, when the blood flows into the human tissue, the semitransparency reduces, when the blood flows back to the heart, the semiransparency increases）. Detects the change by infrared sensors and amplifies the signal through ASIC, thus obtains heartbeat frequency.
