Physiological signal monitoring devices and intelligent bracelet
Technical Field
The invention relates to the technical field of dynamic monitoring equipment, in particular to a physiological signal monitoring device and an intelligent bracelet.
Background
Wearable devices are portable devices that can be worn directly or on the body. The products that appear in the market in the front have intelligent wrist-watch, intelligent bracelet, intelligent glasses, intelligent shoes, intelligent clothes, intelligent necklace etc. in addition, these all can be called wearable device. For real-time dynamic monitoring of human physiological signals (for example, monitoring of heart rate, electrocardiogram and the like), a scheme exists in the related art in which optical heart rate monitoring is integrated on wearable devices such as a smart bracelet or a smart watch, so that real-time dynamic monitoring of the heart rate of a user wearing the smart bracelet or the smart watch is realized.
In the correlation technique, what optical heart rate monitoring on bracelet or the wrist-watch adopted realizes heart rate monitoring based on photoelectricity volume pulse wave technique, and its principle can simply be expressed as beating a bundle of light to wrist skin, detects the light intensity that reflects back. Therefore, the heart rate monitoring device is composed of an LED lamp for emitting light and a sensor for monitoring the intensity of reflected light on hardware. Due to the heart beat, the blood volume in the blood vessel may have a rhythmic change. Some of the light emitted by the LED lamp is absorbed by blood in the blood vessel, and the larger the blood volume is, the more the light is absorbed, and the less the light is reflected back. With the rhythm of heart beat, the blood volume in blood vessel changes periodically, and the intensity of the reflected light detected by us changes. According to the detected light intensity signal change interval, the heart rate of the user can be calculated.
