这里介绍一种电子装置能把脉搏跳动转变为声、光信号。可用于监视病人的心跳及心脏病患者自我检测,本装置体积小,便于携带,电路简单,容易制作。一、电路工作原理平时,用手指触摸手腕上的脉搏,能感到脉搏的跳动。本装置就是将这个信号用传感器(手表式)拾取后转变成电信号,再以声和光的形式(显示器)显 Here is a description of an electronic device can change the pulse beating sound and light signals. Can be used to monitor the patient’s heartbeat and heart disease self-test, the device is small, easy to carry, the circuit is simple, easy to make. First, the circuit works Usually, with your fingers touching the pulse on your wrist, you can feel the pulse beating. The device is the signal with the sensor (watch type) picked up into electrical signals, and then in the form of sound and light (display) was
