Abstract
A wearable heart sound detection system, which includes an acoustic sensing device for collecting heart sound signals of the body, performing signal amplification, filtering, digitization and other preprocessing on the collected heart sound signals, and outputting the preprocessed heart sound signals; a computing electronic device communicatively coupled to the acoustic sensing device for acquiring the preprocessed heart sound signal, and a cloud data database communicatively coupled to the external computing electronic device. The acoustic device includes a capacitive sound sensor, a piezoelectric sound sensor and a circuit assembly. The circuit assembly is respectively electrically connected with the capacitive sound sensor and the piezoelectric sound sensor. The circuit assembly, the capacitive sound sensor and the piezoelectric sound sensor are integrated on a flexible substrate.
