Wearable device and photoelectric pulse sensing assembly

Abstract

The invention provides a wearable device and a photoelectric pulse sensing assembly, and relates to the technical field of electronic devices. The divergence angle of light emitted by a luminous component in the wearable device can be decreased, the utilization rate of the light is increased, thus the detection accuracy of the heart rate, blood oxygen saturation degree and other parameters can beincreased, and power dissipation is reduced; the wearable device includes a substrate, one or more luminous components, light, and one or more lenses, wherein the luminous components are mounted on one side of the substrate, light is configured to emit one or more optical bands, the lenses are arranged on the light emitting sides of the one or more luminous components, each lens corresponds to oneor more luminescent components, and each lens can decrease the divergence angle of the light emitted by the one or more emitting components corresponding to the lens. The photoelectric pulse sensingassembly can be mounted in a wearable object, so that when the wearable object is worn on a target organism, the heart rate, blood oxygen saturation degree and other parameters of the target organismcan be detected.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a wearable device and a photoelectric pulse sensor component. Background technique [0002] A wearable device is a portable device that can be worn directly on a person's body, or integrated into a person's clothing or accessories. With the rapid development of electronic technology, wearable devices can realize more and more functions by detecting parameters such as heart rate and blood oxygen saturation of the human body, such as sports monitoring, health monitoring, sleep monitoring and other functions. [0003] In related technologies, wearable devices usually use PPG (Photoplethysmography, photoplethysmography) pulse wave method to detect parameters such as heart rate and blood oxygen saturation. Among them, PPG is a principle based on photoelectric detection of blood volume changes with pulse pulse A method for measuring parameters such as heart rate and blood o...

Problems solved by technology

[0004] However, during the detection process of the above-mentioned wearable devices, the light loss is relatively serious, which leads to less light entering the human body, and the intensity of reflected light after being absorbed by human blood and tissues is also correspondingly reduced, thereby affecting heart rate and blood oxygen saturation. The detection results of parameters such as temperature and temperature reduce the detection accuracy of parameters such as heart rate and blood oxygen saturation.
