心音描记术中新的应用需要高敏感度、低噪声、以及展宽频率范围的传感器。本文对几种不同的心脏传感器进行了比较,并描述了一种轻便且达到上述目标的加速度型心脏传感器的研制。加速度计重 New applications in phonocardiography require high sensitivity, low noise, and sensors that broaden the frequency range. This article compares several different cardiac sensors and describes a development of an accelerated cardiac sensor that is lightweight and achieves the above goals. Accelerometer weight
