One is a motion state sensor (three-axis acceleration sensor) that can sense three-dimensional rhythms, which uses a capacitive accelerometer to sense motion conditions such as acceleration or vibration in different directions. Simply put, when a person walks normally, two accelerations, horizontal and vertical, are generated. When the user takes a step, the center of gravity rises when one foot touches the ground, and the vertical direction accelerates upward, and the horizontal direction accelerates forward; while the center of gravity falls back when the user continues to walk forward, the vertical acceleration turns downward, and the horizontal acceleration reverses when the foot is retracted. While recording these different acceleration changes, the three-axis accelerometer draws a regular curve, and then uses filtering, peak and valley detection, and other means, using a variety of algorithms and logical operations, and finally converts these data into readable numbers on the bracelet APP, namely the number of steps, distance, and number of calories consumed. The other is the green light photoelectric measurement method, which consists of two green light-emitting LEDs and a photosensor, located on the back of the bracelet. Its working principle is based on the fact that the blood in the arm blood vessels will change in density when pulsating, causing changes in light transmittance. The LED emits green light waves, and the photosensor receives the reflected light from the arm skin. By sensing the changes in light field intensity, the heart rate can be calculated, and then the continuous monitoring of the heart rate can be used to reflect the human body's movement. </span> </div> </div> </div> </div> </div> </div> </div> </div> </div> <p> <br mpa-from-tpl="t"/> </p> <p style="text-align: center;"> <br mpa-from-tpl="t"/> </p> <div data-mpa-template="t" mpa-from-tpl="t"> <div data-mpa-template="t" mpa-from-tpl="t" style="font-size: 17px;"> <div data-role="paragraph" mpa-from-tpl="t"> <div data-id="93476" mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;text-align: center;"> <div data-width="100%" mpa-from-tpl="t" style="display: inline-block;width: 100%;vertical-align: top;border-style: solid;border-width: 1px;border-radius: 0px;border-color: rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -30px;margin-bottom: 10px;font-size: 13px;"> <div mpa-from-tpl="t" style="padding-top: 0.3em;display: inline-block;vertical-align: top;height: 2em;border-bottom: 1px solid rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -0.3em;display: inline-block;vertical-align: top;background-color: rgb(255, 255, 255);font-size: 29px;height: 1em;width: 1.4em;line-height: 1.2em;color: rgb(27, 37, 49);"> <p> <em> <strong mpa-from-tpl="t"> 02 </strong> </em> </p> </div> </div> </div> <div mpa-from-tpl="t" style="margin-top: -10px;"> <div mpa-from-tpl="t" style="padding: 0.5em 0.3em;display: inline-block;border-width: 2px;border-style: solid;border-color: rgba(255, 255, 255, 0);background-color: rgb(255, 255, 255);color: rgb(27, 37, 49);"> <p> <strong mpa-from-tpl="t"> Sleep monitoring </strong> </p> </div> </div> <div mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;margin-bottom: 10px;padding-right: 16px;padding-left: 16px;text-align: justify;font-size: 14px;line-height: 1.75em;letter-spacing: 1.5px;color: rgb(63, 63, 63);"> <p style="text-align: center;"> </p> <p style="margin: 15px 16px 20px;line-height: 1.75em;"> At present, the principle of sleep monitoring in smart bracelets is to analyze the sleep state through the body movement recorder. Simply put, the smart bracelet will have a three-axis acceleration sensor and a photoelectric sensor, which can measure the quality of sleep according to the amplitude, frequency and heart rate of wrist movements during sleep. </p> <p style="margin-left: 16px;margin-right: 16px;line-height: 1.75em;margin-bottom: 25px;"> The three-axis acceleration sensor can detect tiny movements, and the photoelectric sensor can detect heart rate conditions. Then, a certain algorithm is used internally to determine whether the user is awake, in light sleep, or in deep sleep. As for how to determine the user's state, this depends on the preset parameters of the bracelet. The bracelet will preset several trigger conditions to determine whether the user has entered a sleeping state. When the monitoring data of the bracelet matches the preset data, the bracelet will determine that the user has entered the corresponding mode. Of course, different bracelets will have different monitoring result deviations due to differences in hardware and software. </p> </div> </div> </div> </div> </div> </div> </div> </div> <p> <br mpa-from-tpl="t"/> </p> <div style="margin-bottom: 15px;"> <br mpa-from-tpl="t"/> </div> <div data-mpa-template="t" mpa-from-tpl="t"> <div data-mpa-template="t" mpa-from-tpl="t" style="font-size: 17px;"> <div data-role="paragraph" mpa-from-tpl="t"> <div data-id="93476" mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;text-align: center;"> <div data-width="100%" mpa-from-tpl="t" style="display: inline-block;width: 100%;vertical-align: top;border-style: solid;border-width: 1px;border-radius: 0px;border-color: rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -30px;margin-bottom: 10px;font-size: 13px;"> <div mpa-from-tpl="t" style="padding-top: 0.3em;display: inline-block;vertical-align: top;height: 2em;border-bottom: 1px solid rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -0.3em;display: inline-block;vertical-align: top;background-color: rgb(255, 255, 255);font-size: 29px;height: 1em;width: 1.4em;line-height: 1.2em;color: rgb(27, 37, 49);"> <p> <em> <strong mpa-from-tpl="t"> 03 </strong> </em> </p> </div> </div> </div> <div mpa-from-tpl="t" style="margin-top: -10px;"> <div mpa-from-tpl="t" style="padding: 0.5em 0.3em;display: inline-block;border-width: 2px;border-style: solid;border-color: rgba(255, 255, 255, 0);background-color: rgb(255, 255, 255);color: rgb(27, 37, 49);"> <p> <strong mpa-from-tpl="t"> Heart rate monitoring </strong> </p> </div> </div> <div mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;margin-bottom: 10px;padding-right: 16px;padding-left: 16px;text-align: justify;font-size: 14px;line-height: 1.75em;letter-spacing: 1.5px;color: rgb(63, 63, 63);"> <p style="text-align: center;"> </p> <div style="margin: 15px 16px 25px;line-height: 1.75em;"> The principle of heart rate monitoring has been explained in the sports monitoring column. It is listed separately here because the function of heart rate monitoring is not only used in the scope of sports monitoring, but also can be used for continuous attention to health, such as evaluating cardiopulmonary health. You can share the heart rate measurement results with friends through mobile devices such as mobile phones. Some middle-aged and elderly people and people with high risk of chronic diseases can also share data with their family doctors to help doctors observe their conditions more comprehensively and continuously. <span style='font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif;color: rgb(51, 51, 51);letter-spacing: normal;'> </span> <span style='color: rgb(51, 51, 51);letter-spacing: normal;font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif;'> </span> </div> </div> </div> </div> </div> </div> </div> </div> </div> <p> <br/> </p> <p> <br/> </p> <div data-mpa-template="t" mpa-from-tpl="t"> <div data-mpa-template="t" mpa-from-tpl="t" style="font-size: 17px;"> <div data-role="paragraph" mpa-from-tpl="t"> <div data-id="93476" mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;text-align: center;"> <div data-width="100%" mpa-from-tpl="t" style="display: inline-block;width: 100%;vertical-align: top;border-style: solid;border-width: 1px;border-radius: 0px;border-color: rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -30px;margin-bottom: 10px;font-size: 13px;"> <div mpa-from-tpl="t" style="padding-top: 0.3em;display: inline-block;vertical-align: top;height: 2em;border-bottom: 1px solid rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -0.3em;display: inline-block;vertical-align: top;background-color: rgb(255, 255, 255);font-size: 29px;height: 1em;width: 1.4em;line-height: 1.2em;color: rgb(27, 37, 49);"> <p> <em> <strong mpa-from-tpl="t"> 04 </strong> </em> </p> </div> </div> </div> <div mpa-from-tpl="t" style="margin-top: -10px;"> <div mpa-from-tpl="t" style="padding: 0.5em 0.3em;display: inline-block;border-width: 2px;border-style: solid;border-color: rgba(255, 255, 255, 0);background-color: rgb(255, 255, 255);color: rgb(27, 37, 49);"> <p> <strong mpa-from-tpl="t"> Temperature monitoring </strong> <span style="color: rgb(63, 63, 63);font-size: 14px;letter-spacing: 1.5px;"> </span> </p> </div> </div> <div mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;margin-bottom: 10px;padding-right: 16px;padding-left: 16px;text-align: justify;font-size: 14px;line-height: 1.75em;letter-spacing: 1.5px;color: rgb(63, 63, 63);"> <div style="margin: 15px 16px 25px;line-height: 1.75em;"> Body temperature monitoring is achieved through a temperature sensor, which is located on the back of the smart bracelet. Of course, through temperature sensing on both sides of the body, a more accurate human body temperature value can be obtained. The specific working principle is that the sensor collects data and transmits it to the CPU for processing, and then the monitored arm temperature can be displayed on the screen. At the same time, it can also serve as a data basis for further monitoring of health, physiological cycles, etc., and deeply explore the health monitoring and health care functions of smart bracelets. <span style='font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif;color: rgb(51, 51, 51);letter-spacing: normal;'> </span> <span style='color: rgb(51, 51, 51);letter-spacing: normal;font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif;'> </span> </div> </div> </div> </div> </div> </div> </div> </div> </div> <p> <br mpa-from-tpl="t"/> </p> <p style="text-align: center;"> <br mpa-from-tpl="t"/> </p> <div data-mpa-template="t" mpa-from-tpl="t"> <div data-mpa-template="t" mpa-from-tpl="t" style="font-size: 17px;"> <div data-role="paragraph" mpa-from-tpl="t"> <div data-id="93476" mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;text-align: center;"> <div data-width="100%" mpa-from-tpl="t" style="display: inline-block;width: 100%;vertical-align: top;border-style: solid;border-width: 1px;border-radius: 0px;border-color: rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -30px;margin-bottom: 10px;font-size: 13px;"> <div mpa-from-tpl="t" style="padding-top: 0.3em;display: inline-block;vertical-align: top;height: 2em;border-bottom: 1px solid rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -0.3em;display: inline-block;vertical-align: top;background-color: rgb(255, 255, 255);font-size: 29px;height: 1em;width: 1.4em;line-height: 1.2em;color: rgb(27, 37, 49);"> <p> <em> <strong mpa-from-tpl="t"> 05 </strong> </em> </p> </div> </div> </div> <div mpa-from-tpl="t" style="margin-top: -10px;"> <div mpa-from-tpl="t" style="padding: 0.5em 0.3em;display: inline-block;border-width: 2px;border-style: solid;border-color: rgba(255, 255, 255, 0);background-color: rgb(255, 255, 255);color: rgb(27, 37, 49);"> <p> <strong mpa-from-tpl="t"> Blood oxygen saturation monitoring </strong> </p> </div> </div> <div mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;margin-bottom: 10px;padding-right: 16px;padding-left: 16px;text-align: justify;font-size: 14px;line-height: 1.75em;letter-spacing: 1.5px;color: rgb(63, 63, 63);"> <p style="text-align: center;"> </p> <p style="margin: 15px 16px 20px;line-height: 1.75em;"> Blood oxygen saturation refers to the percentage of the combined capacity of oxygen and hemoglobin in the blood to the total hemoglobin capacity, and is an important physiological parameter of the respiratory cycle. Blood oxygen saturation can reflect the body's oxygen supply status. The blood oxygen saturation of a healthy person is generally maintained between 95-100. When the blood oxygen saturation is between 80-85, vision and cognitive abilities will change. When the blood oxygen saturation is around 75, your physical condition is already very dangerous and you need to see a doctor immediately. </p> <div style="margin: 15px 16px 25px;line-height: 1.75em;"> As the intelligence of smart bracelets improves, in order to better serve sports enthusiasts, some manufacturers have begun to add blood oxygen saturation monitoring functions. Its working principle is to calculate the pulse blood oxygen saturation by optimizing the hardware optical path and algorithm, integrating multiple light sources, and taking advantage of the different reflection and absorption rates of oxygenated hemoglobin and deoxygenated hemoglobin to specific light, performing signal extraction, enhancement, noise suppression, algorithm processing and other measures. <span style='font-family: mp-quote, -apple-system-font, BlinkMacSystemFont, "Helvetica Neue", "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei UI", "Microsoft YaHei", Arial, sans-serif;color: rgb(51, 51, 51);letter-spacing: normal;'> </span> </div> </div> </div> </div> </div> </div> </div> </div> </div> <p style="text-align: center;"> <br/> </p> <div style="margin-bottom: 15px;"> <br mpa-from-tpl="t"/> </div> <div data-mpa-template="t" mpa-from-tpl="t"> <div data-mpa-template="t" mpa-from-tpl="t" style="font-size: 17px;"> <div data-role="paragraph" mpa-from-tpl="t"> <div data-id="93476" mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;text-align: center;"> <div data-width="100%" mpa-from-tpl="t" style="display: inline-block;width: 100%;vertical-align: top;border-style: solid;border-width: 1px;border-radius: 0px;border-color: rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -30px;margin-bottom: 10px;font-size: 13px;"> <div mpa-from-tpl="t" style="padding-top: 0.3em;display: inline-block;vertical-align: top;height: 2em;border-bottom: 1px solid rgba(27, 37, 49, 0.46);"> <div mpa-from-tpl="t" style="margin-top: -0.3em;display: inline-block;vertical-align: top;background-color: rgb(255, 255, 255);font-size: 29px;height: 1em;width: 1.4em;line-height: 1.2em;color: rgb(27, 37, 49);"> <p> <em> <strong mpa-from-tpl="t"> 06 </strong> </em> </p> </div> </div> </div> <div mpa-from-tpl="t" style="margin-top: -10px;"> <div mpa-from-tpl="t" style="padding: 0.5em 0.3em;display: inline-block;border-width: 2px;border-style: solid;border-color: rgba(255, 255, 255, 0);background-color: rgb(255, 255, 255);color: rgb(27, 37, 49);"> <p> <strong mpa-from-tpl="t"> Vibration wake-up/reminder </strong> </p> </div> </div> <div mpa-from-tpl="t"> <div mpa-from-tpl="t" style="margin-top: 10px;margin-bottom: 10px;padding-right: 16px;padding-left: 16px;text-align: justify;font-size: 14px;line-height: 1.75em;letter-spacing: 1.5px;color: rgb(63, 63, 63);"> <p style="text-align: center;"> </p> <p style="margin: 15px 16px 20px;line-height: 1.75em;"> The smart bracelet has a built-in vibration component that can wake up the sleeping user through vibration.
