Smart wear, also known as wearable devices, has four main characteristics: 1, which is comfortable or even insensitive to wear; 2. Normal life should not be disturbed during use; 3, the appearance should be suitable for use occasions and environment; 4. Lightweight and wireless are the most basic requirements.
Nowadays, there are many smart wearable products, such as smart glasses, smart bracelets, collars, brain rings, Cosmetic Contact Lenses, baby pajamas and so on. , more widely used in the health field.
Many new smart wearable devices released recently support the function of blood oxygen detection. AppleWatchSeries6 Smart Watch, Glory Watch GSPro and Glory Watch es all support the function of blood oxygen detection. AmazFetGTR 2, GTS2 and vivoWATCH released on September 22nd also support the function of blood oxygen detection. What's the use of more and more common blood oxygen tests? What does this indicator represent? Let's get to know each other.
How important is oxygen saturation?
Cells in the human body live on oxygen, and oxygen entering the human body through the respiratory system will combine with hemoglobin and be transported to various organs. Oxygen saturation is a measure of the percentage of hemoglobin combined with oxygen, so oxygen saturation is a key index to measure health, and the oxygen content in human blood can be known through this parameter.
Generally speaking, the normal oxygen saturation is between 95% and 100%. If the oxygen saturation is less than 90%, it can be considered as hypoxemia. Low oxygen saturation means hypoxia, which will affect the central nervous system, liver, kidneys and other important organs. Therefore, oxygen saturation is an important index, and the measured data can help to judge the current health status.
Although the newly released AppleWatchSeries6 is the first time to add the blood oxygen detection function, many smart devices already support the blood oxygen detection function. HUAWEIWATCHGT2 smart watch, Glory Bracelet 5 and some Samsung mobile phones all support the blood oxygen detection function, so the blood oxygen detection function on smart devices is nothing new.
These smart wearable devices that support blood oxygen detection generally release light beams with different wavelengths through light emitting diodes. The ratio of hemoglobin carrying oxygen can be judged by using the difference of absorption rate of hemoglobin carrying oxygen to beams with different wavelengths, that is, the saturation of bleeding oxygen can be detected.
The newly released AppleWatchSeries6 also detects oxygen saturation in a similar way. According to Apple, AppleWatchSeries6 is equipped with a brand-new blood oxygen sensor, which consists of four groups of LED clusters and four photodiodes. It will irradiate blood vessels with different light and measure the amount of reflected light at the same time. With the blood oxygen APP, you can calculate the oxygen content, and it is relatively simple to use in practice.
Application Scenario of Oxygen Saturation Detection
Because blood oxygen saturation can be detected anytime and anywhere through smart wearable devices, the application scenarios of blood oxygen detection are very extensive.
The function of oxygen saturation detection can help to judge the state of sleep breathing. For example, intermittent apnea may occur during sleep, resulting in insufficient oxygen supply. Continuous blood oxygen testing can record the data of blood oxygen saturation during sleep, and analyze whether there is hypoxia during sleep through the data, so as to judge the sleep health state.
In addition, like some people who often work overtime, they can also judge the current state through the oxygen saturation detection function. If the oxygen saturation is low, they need to take a quick rest, which is more friendly to their health.
The function of detecting blood oxygen saturation can not only make you know your physical condition at any time in your daily life, but also play a better health auxiliary role in some special scenes. For example, in outdoor extreme mountaineering and other sports scenes, you can know your physical condition at any time through blood oxygen saturation and judge whether you need to rest or adjust your exercise intensity, so as to better cope with various sports scenes.
Generally, apps on mobile phones can synchronize the health data of smart wearable devices, so even when you are away from home, you can get to know your parents' blood oxygen data and other health data by means of remote synchronization data. Let your care add more details.
summary
Oxygen saturation is an important index to measure health. Adding the function of blood oxygen detection to smart wearable devices can make the detection more comprehensive, and can be combined with other detection data to let you know your physical condition more clearly and in detail, which can play a greater reference role. Smart wearable devices that are constantly upgrading around health monitoring can make it easier for ordinary people to understand their physical condition and add more protection.
Nowadays, many smart wearable devices support the function of blood oxygen detection, so it is convenient to measure blood oxygen saturation. However, it is not easy to make the blood oxygen detection function play a greater role. For example, the accuracy of blood oxygen saturation detection is also critical, because it is related to the reliability of data. Of course, the data provided by most smart wearable devices are for reference only. In addition, if continuous blood oxygen detection is to be realized, the endurance requirements of smart wearable devices will be higher, which will directly affect the experience of blood oxygen detection function.
What are the opponent parameters?
A brief introduction to the observation parameters is as follows:
1. weight
Considering daily wear and exercise, the self-weight of the watch is the key factor to be considered first. Watches must be light to carry around 24 hours a day. Let's take a look at the weight parameters of oppowatch:
Official weight data of oppowatch style.
Official weight data of oppowatch style.
The heaviest stainless steel watch weighs 45.5g, even lighter than an egg (about 50g), while the female 4 1mm watch only weighs 29.7g, which is the lightest of all smart watches with heart rate esim card function at present. Weight is a small detail that long-term sports enthusiasts will pay attention to, and oppo obviously pays attention to the comfort of weight for long-term sports, and the weight parameters created can be said to be sincere and excellent.
2. Water resistance
The second consideration of sports watches is waterproof and sweat-proof. If you sweat for a long time, you must reach a higher ATM compression and waterproof level.
Opposing waterproof standard level
Opposing waterproof standard level
Different models of OPPOWatch have different waterproofness. For 46mn dial, 5ATM waterproof is supported, and for 4 1nm dial, only 3ATM waterproof is supported.
Here, I want to make it clear that 3ATM waterproofing does not mean supporting waterproofing within 30 meters underwater. Many netizens will misunderstand: 3ATM refers to being able to withstand 3 atmospheric pressure standards and being in a laboratory environment; Therefore, in the actual environment, 3ATM watches can not be taken to swim, but can only be used for waterproof life, sweating, splashing water or long-term rain; 5TM is only suitable for short-distance swimming in shallow water at most. For long-distance swimming or diving, the watch must be at least 10ATM waterproof.
Therefore, in terms of waterproofing, if everyone has swimming scenes, 3ATM's 4 1nm dial is not applicable. It is not recommended that you wear it in the shower.
At present, most smart sports watches on the market are also 5ATM standards, so oppo is qualified in waterproof, and the styles should be carefully selected according to their own usage scenarios.
3. Heart rate detection
If you want to do scientific exercise, heart rate detection is very important.
We can control the rhythm and intensity of exercise through the heart rate value, so that our exercise time is within the state range needed to achieve the goal.
Oppowatch also has an optical heart rate detection function. As I said in my last article, it is of course impossible to match the accurate performance of optical heart rate with ECG detection (mainly due to too many environmental factors), and most manufacturers need to adjust the detection results through algorithms. At present, OPPO and the Sports Science Research Institute of the State Sports General Administration cooperate exclusively with GoMore to establish a physical fitness model according to your physical condition. I believe that the cooperation of this algorithm will play a certain role in the accurate performance of heart rate test.
However, daily exercise, such as sprinting, jogging, fitness, etc., does not require high accuracy of heart rate, and the average value of basic heart rate meter test is relatively accurate.
But if you want to carefully control sports, such as triathlon and marathon, you must wear a heart rate belt when training. Of course, people with this demand are generally athletes or marathon enthusiasts. We ordinary people don't need to be so precise.
At present, oppo's heart rate detection does not support external heart rate band for the time being, but because the system is based on coloros developed by Android, it is not difficult to develop an interface to realize docking.
Therefore, the heart rate and oppowatch meet the basic needs and meet the standards.
Exercise and socializing
Sports need supervision, and effective supervision, communication and guidance are also very important for sports to effectively achieve their goals. Everyone wants to have a group of like-minded brothers who cheer each other up and compete with each other every day.
Oppo also noticed the positive role of socialization in promoting sports. In the system, the sports platform APP support and data docking for Glug and Fit are realized. You can put your usual sports records in your own sports circle to punch in and share your sports records and status.
OPPOwatch currently supports applications.
OPPOwatch currently supports applications.
Oppo did not adopt a closed sports APP design, but developed a data interface, which is superior to many smart sports watches, which is excellent. I look forward to developing more support for app and platform data interface in the future.
5.8GBROM, massive songs;
OppoWatch has 1 GB RAM and 8 GB ROM. This parameter is basically twice that of smart watches with storage space on the market. At present, the mainstream configuration on the market is 5 12RAM and 4GBROM, and the configuration of OPPO at this price is also kind;
In addition to the space for system and APP installation and data storage, the watch can basically store more than 4G of music space. Support QQ music, cool me and Himalayan, and synchronize member music.
This is also the advantage of an open platform. With the function of storing and playing music, you can have a fun sport by simply bringing a Bluetooth headset and a smart watch when you go out.
6.eSIM function
Put this in the sixth point, because this function is not just needed for sports smart watches, and if it is, it can't be said to be a secondary function of real fragrance.
With the eSIm function, the mobile phone can be free.
With the eSIm function, the mobile phone can be free.
With the esim function, you really don't need to bring your mobile phone, which is good news for those who have busy business, complicated interpersonal relationships and are keen on sports!
Step 7 be patient
As long as there is Esim function, the endurance will not be too strong. Simply put, if the esim function is turned on, the watch will always send and receive signals and receive information and data. At this time, it is really equivalent to a telephone.
However, oppowatch is unique in that it does not adopt the latest Snapdragon single chip scheme, but adopts the low-power chip combination scheme of Snapdragon 2500 and apolo3, which solves the energy consumption problem brought by esim as much as possible. The smart mode reaches more than 1 day (officially announced for 40 hours), and the battery life performance is slightly better than other brands of esim smart watches. After all, the latest chip 3 100 in Snapdragon has not been listed yet, which is believed to be the best solution for the current esim smart meter.
I won't elaborate on the long battery life mode here, because it doesn't have much reference value. You can buy a smart watch without intelligence. . .

8. Playing the dial, sports and fashion are all right.
In terms of software functions, what surprises me most is its diverse dial design customization function, which can not only customize the dial style, parameters and background photo album, but also use AI to shoot and generate a dial suitable for your clothes, play new tricks and become an absolute sports fashionista!
9. Quick-release strap is convenient to wear in different scenes.
Quick release strap is a very convenient function, which can switch between work, business and sports scenes. It only takes ten seconds to change the strap, and it won't get in the way. Some people will say that it's over without changing the strap. If it's a rubber strap, no problem. Cowhide and steel belt are neither sweat-proof nor corrosion-resistant, and their sports comfort will be affected, so they should be replaced.
Besides, who doesn't want to change the pattern and match it? However, at present, oppowatch has only rubber and cowhide straps to choose from, and we look forward to launching more strap options!
Well, that's enough comments about key functions. Others, such as fast charging, I won't introduce them in detail here. If you are interested, I attach the link of the official flagship store for everyone to know.
To sum up:
Oppowatch basically meets the needs of daily exercise, with light weight, waterproof and sweat-proof (waterproof styles have different attention choices) and optical heart rate, which can scientifically control exercise intensity and socialization. Compared with other brands, OPPO Watch has obvious advantages in weight and social interaction. In addition, with esim and 8GB of large-capacity memory, sports can completely abandon the mobile phone and become easier and more convenient. The endurance is not too weak because of esim, and it is quite satisfactory.
There are many patterns on the dial, AI changes its face at will and has strong soft power. Pay attention to women in many details, such as the menstrual reminder of grapefruit App, the design of dial strap is small and light, and the fashionable style feels tailor-made for girls who love to dress up.
From the realization of hardware parameters and software functions, I personally think that it ranks in the first echelon of smart wear in daily sports, the price is below 2000, the hardware configuration and shape materials are quite kind, and the cost performance is high, which can be regarded as an innocuous smart wear product.
Ps: At present, the software only supports Android, and it will take some time for IOS.
