通过听诊器获得的肺音被广泛用于诊断和鉴别呼吸系统疾病。虽然已经建立了广泛的专门知识来解释这些声音并识别与某些模式相关的疾病，但其有效使用仅限于从业者的个人经验。这种用户依赖性表现为阻碍这种有价值的诊断工具数字化转型的一个因素，这种诊断工具可以通过在现实生活条件下持续长期呼吸监测来改善患者的预后。特别是患有进行性呼吸系统疾病的患者，如慢性阻塞性肺病，预计将受益于长期监测。最近，COVID-19大流行也显示出缺乏可随时部署在操作条件下同时需要最少患者教育的呼吸监测系统。为了特别解决后一个问题，在这篇文章中，我们提出了一个声音采集模块，它可以集成到一个专用的服装，从而最大限度地减少病人的角色定位听诊器和施加适当的压力。我们实现了一个无阻尼声电换能器，通过堆叠硅橡胶和压电薄膜来捕获具有最小衰减的胸部声音。此外，我们用临床实践中广泛使用的电子听诊器对我们的设备进行了基准测试，以量化其性能。
Lung sounds acquired by stethoscopes are extensively used in diagnosing and differentiating respiratory diseases. Although an extensive know-how has been built to interpret these sounds and identify diseases associated with certain patterns, its effective use is limited to individual experience of practitioners. This user-dependency manifests itself as a factor impeding the digital transformation of this valuable diagnostic tool, which can improve patient outcomes by continuous long-term respiratory monitoring under real-life conditions. Particularly patients suffering from respiratory diseases with progressive nature, such as chronic obstructive pulmonary diseases, are expected to benefit from long-term monitoring. Recently, the COVID-19 pandemic has also shown the lack of respiratory monitoring systems which are ready to deploy in operational conditions while requiring minimal patient education. To address particularly the latter subject, in this article, we present a sound acquisition module which can be integrated into a dedicated garment; thus, minimizing the role of the patient for positioning the stethoscope and applying the appropriate pressure. We have implemented a diaphragm-less acousto-electric transducer by stacking a silicone rubber and a piezoelectric film to capture thoracic sounds with minimum attenuation. Furthermore, we benchmarked our device with an electronic stethoscope widely used in clinical practice to quantify its performance.
