Smart watches have added more and more functions, such as eSIM, GPS, sleep monitoring, heart rate monitoring, blood oxygen monitoring and so on.
In daily life, our common devices for detecting body fat are body fat scale and sebum forceps.
Body fat scale is a weighing instrument that can measure fat, moisture and so on besides weight. The principle of human body fat scale is that muscle contains more water such as blood and can conduct electricity, while fat is not. Because the channel conductor of current in the body is muscle, the weight of muscle can be known from the difficulty of current passing, so as to judge the proportion of muscle in the weight.
Sebum forceps are instruments for detecting human body fat. Its advantages are convenient to carry and simple to use, but it is necessary to calculate body fat according to the formula.
Can I measure body fat with a smart watch?
The technical principle of measuring body fat by smart watch is similar to that of human body fat scale, and the wearer's body fat is measured by bioelectrical impedance technology. Samsung conducted a clinical experiment and recruited 203 volunteers aged 65,438+08 ~ 68 at St. Mary's Hospital in Seoul. Samsung integrates the wristband and body of wearable devices into special sensors for data collection. After putting on the equipment, volunteers press the sensor on the front of their bodies with their fingers to form a current circulation with the human body, and then complete the body fat detection. The whole process is similar to measuring ECG with AppleWatch.
Samsung filed a patent on 20 15, which also indicates that Samsung may be developing a wristband with body fat measurement function, and will add a new function called "BodyComposition" to its smart wearable products, which allows users to measure body fat percentage through smart watches.
According to the patent document, the watchband is equipped with electrodes. When measurement is needed, the user only needs to put two fingers at the relevant positions for bioelectrical impedance analysis (BIA), that is, the ratio of fat to water can be calculated by using low-power current, and the resistance between adipose tissue and non-adipose tissue can be analyzed.
So far, there is no small device like smart watch on the market to measure the body fat of BIA. If Samsung's patent can be realized, it will be the same as the ECG function of AppleWatchSeries4, which is a major breakthrough for wearable devices in the field of health care.
What is the difference between smart watches that do health monitoring, such as Le Jiu Watch, Huawei and Xiaomi?
The difference between Lejiu Watch, Huawei and Xiaomi Smart Watch;
First, Xiaomi smart watch
1, product name: Mi Dai 5;
2, battery life: 14 days long battery life, magnetic charging;
3. Sensors: high-precision six-axis sensor, PPG heart rate sensor.
3. Supported sports types: outdoor running, walking, cycling, indoor running, swimming in the pool, sports, indoor cycling, elliptical machine, skipping rope, yoga, rowing machine, running, automatic walking detection, pace reminder, full kilometer reminder and high heart rate reminder;
4. Health: 24-hour heart rate sleep monitoring+women's health;
Second, Huawei smart watches
1, product name: Huawei bracelet 4;
2, battery life: the use time in typical scenes is up to 7 days;
3. Sensors: 3-axis acceleration sensor, optical heart rate sensor and infrared wear detection sensor;
4. Support sports types: outdoor running, walking, cycling, mountain climbing, indoor riding, hula hoop, rowing machine, automatic detection of running and walking;
5. Health: blood oxygen test, sleep monitoring, continuous heart rate monitoring, static high heart rate reminder, static low heart rate reminder;
Third, Lejiu smart watch
1, product name: Lejiu smart watch;
2, battery life: the use time in a typical scene is up to 3 days;
3. Sensors: professional monitoring sensors;
4. Support sports types: support the detection of outdoor running, walking, cycling, mountain climbing, indoor cycling and other sports;
5. Health: health examination, exercise sleep monitoring;
Extended data:
Recommended:
1, if you only look at the cost performance, Xiaomi is more recommended. Its main function is to check the amount of exercise and monitor the quality of sleep.
2. I think it has more functions and the bracelet is more comfortable. I recommend Huawei, which also focuses on sports monitoring, but adds automatic identification and recording of users' various sports routes and frequencies, including walking, running, climbing and cycling.
In order to monitor your health more professionally, I recommend Lejiu smart watch. The product positioning of this brand is completely different from that of Xiaomi Huawei. Lejiu Watch is to analyze the health risks of users, timely warn and remind them of abnormalities, assist in rescue and push various health reports to users every week.
The smart watch for health detection focuses on the ECG detection function of ZeppZ smart watch. At present, there are few smart watches that can do ECG detection on the market. ZeppZ has made a great breakthrough in this function. It is equipped with an electrode ECG sensor, which allows us to quickly obtain ECG data and timely warn potential heart problems and risks through the detected data. In addition, it is equipped with the most concerned blood oxygen detection function, which can detect blood oxygen saturation anytime and anywhere, and the blood oxygen data is more accurate.
What brand of smart health monitoring watch should I buy?
At present, there are many smart monitoring watches on the market, but the emphasis is still different. For example, watches for exercise, sleep, blood oxygen and heart rate also include exercise, daily life and health management. If you are a smart watch that mainly monitors sports data, Garmin is the first choice. In this respect, Garmin's watches are more professional, which can help you understand your physical condition and double the exercise effect.
What brand of watches are used to monitor heart rate and blood pressure?
At present, brand watches that can measure heart rate and blood pressure, such as Huawei's smart watches and Xiaomi's sports smart watches, or bracelets, can monitor heart rate online in real time and can work all day, and these brands are also relatively mature smart watches in China, which can be used as a reference.
