Wearable device and control method thereof

Abstract

The present application discloses a wearable device and a control method thereof, the wearable device comprises a housing, a main circuit disposed inside the housing, the housing includes a bottom case, an elastic component, and a sensor component for detecting the physiological index of a user, an inner side of the elastic component is disposed around the sensor component, an outer side of the elastic component is connected to the bottom case, the sensor component is electrically connected to a main circuit, and when the physiological index of the user is required to be detected, the elasticcomponent is caused to be close to the skin of the user by elastic deformation. By providing the elastic component on the wearing device, when the user wears the wearable device to measure the physiological index, the elastic component deformation causes the sensor component to automatically float up, which fills a gap between the wearing device and the user's skin, reduces looseness and other phenomena, and improves measurement accuracy.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201711351099.X and the invention title "An Elastic Electrode Structure and Wearable Device" filed with the China Patent Office on December 15, 2017, the entire contents of which are incorporated by reference in this application. technical field [0002] The present application relates to the field of terminals, in particular to a wearable device and a control method thereof. Background technique [0003] With the development of smart terminal technology, wearable devices such as smart watches and smart bracelets currently on the market will add some sensors to measure the user's physiological indicators. [0004] For example, a smart watch or bracelet can be set to measure heart rate with a photoplethysmograph (Photoplethysmograph, PPG), and an electrocardiogram (ECG) to measure ECG, and its functional modules can be set and fixed on the back of the watch case, or On th...

Problems solved by technology

[0004] For example, a smart watch or bracelet can be set to measure heart rate with a photoplethysmograph (Photoplethysmograph, PPG), and an electrocardiogram (ECG) to measure ECG, and its functional modules can be set and fixed on the back of the watch case, or On the inside of the bracelet, the height of the module is limited by factors such as appearance and comfort. There may be a certain raised height but not too high, so it cannot guarantee the need to stick to the skin in various wearing scenarios

[0005] However, the commonly used optical or electrical signal sensors require close contact with the skin to measure accurately, otherwise the optical or electrical signals will be unstable due to the shaking of the sensor, and the signal is weak and of poor quality, making it difficult to extract effective data for calculation. Always wear the watch bracelet tightly, because too tight will oppress blood circulation and cause user discomfort
