Abstract: A wearable device (100) includes a body (1) and a detection electrode (21). The body (1) includes an electrocardiosignal collection circuit (11), and an inner electrode (12) and an outer electrode (13) that are electrically connected to the electrocardiosignal collection circuit (11). The inner electrode (12) is configured to collect an electric potential signal of a first wearing position (200), and the outer electrode (13) is configured to collect an electric potential signal of a non-wearing position (300). The detection electrode (21) can move relative to the body (1), and the detection electrode (21) is configured to electrically connect to the electrocardiosignal collection circuit (11) and collect an electric potential signal of a second wearing position (400). The non-wearing position (300) and the second wearing position (400) are different from the first wearing position (200). The wearable device (100) can measure electrocardiosignal data in time.

Abstract: An ECG detection method includes in a wearable device, a first electrode detects a first electrical signal and a second electrode detects a second electrical signal, a processor determines a frequency bandwidth based on a current status of the wearable device and/or a status of a user in contact with the first electrode and the second electrode, and the processor determines an electrocardiogram ECG based on an electrical signal that is in the first electrical signal and the second electrical signal and for which a frequency falls within the frequency bandwidth. The wearable device selects an appropriate frequency bandwidth based on the status of the wearable device and/or the status of the user in contact with the first electrode and the second electrode, and then obtains the ECG based on the frequency bandwidth.

Abstract: A wearing prompt method for a wearable device and an apparatus, and related to the field of communications technologies, to reduce a probability that the wearable device cannot accurately measure physiological parameters of a user, thereby improving accuracy of measuring the physiological parameters of the user. The method includes: obtaining, by the wearable device, a target PPG (photo plethysmo graph) signal; and prompting, by the wearable device when the target PPG signal is inconsistent with a stored reference wearing parameter, a user to adjust a wearing position of the wearable device and to adjust tightness of wearing the wearable device.
