Wearable Devices and Photoelectric Pulse Sensing Components

Abstract

The invention provides a wearable device and a photoelectric pulse sensor assembly, which relate to the technical field of electronic devices, can reduce the divergence angle of the light emitted by the light-emitting parts in the wearable device, improve the utilization rate of light, and thereby increase the heart rate And the detection accuracy of parameters such as blood oxygen saturation and reduce power consumption. Wherein, the wearable device includes: a substrate; at least one light-emitting component installed on one side of the substrate, configured to emit light of at least one light wavelength band; at least one lens arranged on the light-emitting side of the at least one light-emitting component, and each lens corresponds to At least one light emitting component, each lens can reduce the divergence angle of the light emitted by the corresponding at least one light emitting component. The above-mentioned photoelectric pulse sensor component can be installed in the wearable object, so that when the wearable object is worn on the target organism, the parameters such as heart rate and blood oxygen saturation of the target organism can 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.
