  • Publication number: 20180028125
    Abstract: A health care system including a cloud database, a physiological sensor and a processor is disclosed. The cloud database is configured to store a reference waveform and an abnormal data record. The physiological sensor is configured to detect a detected part of a body and to generate a detected physiological signal. The processor is electrically connected to the cloud database and retrieves the reference waveform from the cloud database. The processor is electrically connected to the physiological sensor to receive the detected physiological signal, converts the detected physiological signal into a physiological waveform, compares the physiological waveform with the reference waveform to determine a frequency error and a peak error therebetween, and generates a driving signal when the frequency error is not smaller than a frequency threshold and the peak error is not smaller than a peak threshold. Advantageously, the efficiency of health management can be improved.
