Wearable apparatus for ECG signal acquisition
First Claim
1. A method for measuring an electrocardiograph (ECG) signal for a user wearing a wearable device, comprising:
- receiving motion information of the wearable device;
determining, using the motion information, whether to measure the ECG signal using a first mode or a second mode, wherein the first mode comprises an episodic mode and the second mode comprises a continuous mode;
when the ECG signal is measured in the first mode, receiving the ECG signal by an ECG sensor from a closed circuit formed by a first ECG sensor electrode and a second ECG sensor electrode, wherein the wearable device comprises a main body detachable to the wearable device, a connecting portion, and electrode patches, and the main body comprises the ECG sensor, the first ECG sensor electrode, and the second ECG sensor electrode; and
when the ECG signal is measured in the second mode, receiving the ECG signal by the ECG sensor from a closed circuit formed by electrodes of the electrode patches, wherein the ECG sensor is in the main body and the main body is connected to the electrode patches,wherein when the ECG measurement is performed in the second mode, the main body is detached from the wearable device and connected to the electrode patches by snap-fit or adhesive, and a securing portion is detached from the main body and the electrode patches.
