Abstract

This paper presents a comprehensive review of cardiorespiratory auscultation sensing devices (i.e., stethoscopes), which is useful for understanding the theoretical aspects and practical design notes. In this paper, we first introduce the acoustic properties of the heart and lungs, as well as a brief history of stethoscope evolution. Then, we discuss the basic concept of electret condenser microphones (ECMs) and a stethoscope based on them. Then, we discuss the microelectromechanical systems (MEMSs) technology, particularly focusing on piezoelectric transducer sensors. This paper comprehensively reviews sensing technologies for cardiorespiratory auscultation, emphasizing MEMS-based wearable designs in the past decade. To our knowledge, this is the first paper to summarize ECM and MEMS applications for heart and lung sound analysis.

摘要

本文对心肺听诊传感设备（即听诊器）进行了全面综述，有助于理解其理论方面和实际设计要点。本文首先介绍了心肺的声学特性以及听诊器的简要发展历史。然后，讨论了驻极体电容麦克风（ECM）的基本概念以及基于该麦克风的听诊器。接下来，讨论了微机电系统（MEMS）技术，特别是聚焦于压电换能器传感器。本文全面回顾了心肺听诊传感技术，重点介绍了过去十年中基于 MEMS 的可穿戴设计。据我们所知，这是第一篇总结 ECM 和 MEMS 在心肺音分析中应用的论文。
