The integrated patch of ECG and phonocardiogram sensors includes a patch with an adhesive layer, a phonocardiogram probe and a plurality of ECG electrodes on the patch, wherein the ECG probe and the phonocardiogram probe are both exposed from the adhesive layer, wherein three ECG electrodes are arranged in a triangular structure, and two of the three ECG electrodes form limb leads respectively. The present invention integrates both ECG electrodes and phonocardiogram probes on one patch, and can obtain an ECG and a phonocardiogram at the same time.

A system and method for determining heart-related biometric data is presented that includes an earpiece device device to receive audio signals and isolate right and left heartbeat signals from the received audio signals, an extraction module to process the isolated right and left heartbeat signals to generate right and left PCG1, PCG2 signals, a pre-processing module to perform signal processing on the PCG1, PCG2 signals to determine PTT11, PTT12 signals, and a processing module to perform signal processing on the PTT11, PTT12 data signals to provide an indication of heart-related conditions. Furthermore, incorporating morphological detection techniques on the PCG1, PCG2, PTT11, PTT12 signals to generate an MD data signal and incorporating a user-wearable device to generate a third heart-related signal that is further processed to generate PTT2, PTT3 data signals.

The invention relates to an intelligent wearable heart sound detection system, and belongs to the technical field of sensors. The intelligent wearable heart sound detection system comprises a wearable high-sensitivity sensor, a signal processing system, a machine learning system and an AI data processing system. The wearable high-sensitivity sensor collects heart sound of a user to generate a sensor signal; the signal processing system processes the sensor signal to generate a heart sound signal; the machine learning system establishes and updates a heart sound computer model through a machine learning algorithm; and the AI data processing system draws a phonocardiogram reflecting heart sound characteristics based on the heart sound computer model and the heart sound signals. Therefore, cardiac murmur can be visually reflected on the phonocardiogram to serve as a reference basis for a user and a doctor to judge the heart health condition, meanwhile, the wearable high-sensitivity sensor is adopted so that cardiovascular examination can be conducted through daily wearing, the use method is convenient, and the application range is quite wide.
