WEARABLE DEVICE AND MEASUREMENT SYSTEM AND METHOD CAPABLE OF DETECTING BIO-IMPEDANCE AND ELECTROCARDIOGRAM

A wearable device and a measurement system and method capable of detecting bio-impedance and electrocardiogram. The wearable device comprises: a housing, a watchband, and four electrode sheets (P1, P2, P3, P4) used for detecting bio-impedance and electrocardiogram information; the watchband is connected to the housing; two electrode sheets (P1, P2) among the four electrode sheets (P1, P2, P3, P4) are provided on the front surface of the housing, the other two electrode sheets (P3, P4) are provided on the back surface of the housing. According to the wearable device, both bio-impedance and electrocardiogram signal measuring functions can be achieved, the bio-impedance is measured by using a four-electrode method, electrocardiogram measurement is completed by using three electrode sheets (P2, P3, P4) among the four electrode sheets (P1, P2, P3, P4) in combination, therefore, the device structure is optimized, the device volume is reduced, the cost is lowered, and the measurement precision is also ensured.
