Ultra-light Silicon-based Bionic Acoustic Patch for Long-term Cardiopulmonary Remote Monitoring

Clinical traditional stethoscopes can only realize short-term in-hospital detection, failing to capture dynamic cardiopulmonary acoustic signals in daily activities, which limits the early diagnosis of chronic cardiopulmonary diseases. This study develops a 3-gram ultra-light silicon-based bionic acoustic patch. The flexible patch can be tightly attached to the chest surface for long-term wearing, efficiently collecting high-precision heart sound and lung sound signals in daily motion states. Combined with intelligent algorithm analysis, the device realizes real-time remote monitoring of cardiopulmonary hemodynamic changes, providing continuous dynamic data support for early warning and long-term management of cardiopulmonary diseases.
