Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment provides a wearable device, which comprises a processor, at least one first electrode, at least one second electrode, a display screen and a cover plate; the processor is electrically connected with the first electrode, the second electrode and the display screen; the cover plate is arranged on the display screen and comprises a visible area covering the display screen and a non-visible area surrounding the visible area; the second electrode is arranged on the shell of the wearable device and is used for being in contact with the skin of a user where the wearable device is worn, and the first electrode is attached to the cover plate; the first electrode and the second electrode are used for collecting ECG signals of the user and transmitting the ECG signals to the processor, and the processor acquires electrocardio information of the user according to the ECG signals.

In the prior art, at least two ECG electrodes are needed for electrocardiogram detection, and the ECG electrodes are contacted with a human body to form a detection loop so as to realize electrocardiogram detection. Typically, the ECG electrode is formed by plating a conductive material on a metal plate, and is an opaque metal plate electrode that is disposed on the housing of the wearable device without overlapping the cover plate.

Generally, after the user wears the wearable device, the at least one second electrode is in direct electrical contact with the skin surface of the person where the wearable device is worn, while the at least one first electrode is in contact with the skin of the user outside the wearable device, typically by touching the person with a finger. The first electrode is generally in the same plane with the cover plate, and the first electrode is arranged in other areas except the cover plate on the plane, so that the area occupied by the cover plate and the first electrode on the same plane of the wearable device is the sum of the areas occupied by the cover plate and the first electrode, the area of the plane of the wearable device is larger, and the volume of the wearable device is correspondingly increased. In the application, the conductive material is attached to the cover plate to form the first electrode touched by a finger, so that the area occupied by the cover plate and the first electrode on the plane of the wearable device is smaller than the sum of the areas occupied by the cover plate and the first electrode, and the size of the wearable device can be correspondingly reduced. It is noted that "attaching a conductive material to the cover plate" includes attaching the conductive material to the cover plate in whole or in part.

Alternatively, the first electrode may be an opaque conductive layer, such as a titanium alloy.

Optionally, when the first electrode is an opaque conductive layer, the first electrode is attached to the non-visible region of the cover plate in a ring-shaped pattern. Referring to fig. 1 and 2, fig. 1 is a left side view of a non-visualization region where the first electrode is attached to the cover plate in a ring-shaped pattern, and fig. 2 is a corresponding front view. In fig. 1, a cover plate 20 is included, a lens screen printing ink area 21, the lens screen printing ink area 21 is an opaque material, 22 is an opaque first electrode, and 23 is a display screen, so that the opaque first electrode can be seen to overlap with the lens screen printing ink area, that is, the first electrode is attached to a non-visual area of the cover plate. Compared with the prior art that the opaque electrodes and the silk-screen printing ink area of the lens cannot be overlapped, the size of the wearable device can be reduced by the scheme in the application.

The first electrode is a transparent conductive layer, and can be set to any shape according to requirements, and is located in a visible area or a non-visible area of the cover plate, or is located in both the visible area and the non-visible area. Referring to fig. 3, a left side view of the transparent first electrode connected to a part of the components is shown, including a cover plate 30, a display screen 31 and a transparent first electrode 32, wherein the transparent electrode is attached to the cover plate, thereby reducing the volume of the device.

Optionally, the second electrode is located at the bottom of the wearable device, the first electrode and the second electrode are parallel to each other, and the second electrode is in electrical contact with the skin of the user where the wearable device is worn. In some existing wearable devices, such as a bracelet, an electrode for contacting a finger is arranged on the side of the wearable device to form a key, and an electrode for contacting the skin where a user wears the wearable device is arranged on the bottom of the wearable device, but the existing scheme has the disadvantages that: when electrocardiogram detection is carried out, the electrodes on the side face of the device are pressed, meanwhile, the device is required to be vertically pressed, so that the electrodes on the bottom of the device are in contact with the skin of a user, and the electrocardiogram detection is not convenient to operate. And in this application, through setting up the bottom of second electrode at wearable equipment, just first electrode is located on the apron, consequently first electrode and second electrode are parallel to each other, and the user only needs the operation of one vertical pressure wearable equipment, can realize that first electrode and second electrode contact user's skin simultaneously, and the operation is succinct more.

Optionally, the process of attaching the first electrode to the cover plate is PVD.

Optionally, the wearable device comprises a PPG sensor connected to the processor, the PPG sensor being configured to acquire an electrical photoplethysmogram signal of the user and transmit the electrical photoplethysmogram signal to the processor, and the processor acquires a biological characteristic of the user, such as heart rate information and blood pressure information, from the electrical photoplethysmogram signal.

It should be noted that, without conflict, the embodiments and/or technical features in the embodiments described in the present application may be arbitrarily combined with each other, and the technical solutions obtained after the combination also fall within the protection scope of the present application.

It should be understood that the specific examples in the embodiments of the present application are for the purpose of promoting a better understanding of the embodiments of the present application, and are not intended to limit the scope of the embodiments of the present application, and that various modifications and variations can be made by those skilled in the art based on the above embodiments and fall within the scope of the present application.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
