Can Huawei mobile phone develop an app that can measure body temperature through infrared rays?

I am glad to be able to answer your question.

First, there is a software called temperature detection, which can be found in Huawei market. It doesn't feel accurate. Every test is different. Do you have a fever? Try a fever to see if it is accurate. This seems to be foreign software. By the way, this software has many advertisements.

Second, Huawei's mobile phone itself does not support functions such as measuring blood pressure, indoor temperature, body temperature and heartbeat. It may be because the temperature detector needs many parts and is too thick to be installed on the mobile phone, but the technology will definitely solve this problem in the end.

Third, during the national epidemic, any community should take temperature. If Huawei's mobile phone can break through this function, it will be cool, and it will absorb countless powders in an instant, which will also solve most problems. Recently, Huawei's HarmonyOS system and HMS have confronted Google's Android system and GMS. Huawei has produced a lot of hard-core things, which won the hearts of the people, and everyone's expectations for Huawei are higher. I still hope that in this battle, I will fight a Jedi counterattack and attack the world perfectly.

Finally, I hope my answer can help you or give you more inspiration.

To do infrared temperature measurement of mobile phone, hardware, namely infrared temperature sensor, must be involved.

First, this is the probe of an ordinary infrared thermometer, which is about 1 cubic centimeter. What needs to be done is to miniaturize it and install it in a mobile phone.

And equipped with corresponding signal processing chips and circuits. Of course, this can be integrated into the motherboard. However, with the current trend of modular mobile phones, it is better to make one separately, and it is better to connect it with the motherboard with wires, which is also convenient for subsequent maintenance.

Second, another idea is to connect the mobile phone to read data through wireless or wired connection, so that the temperature can be measured without changing the configuration of the existing mobile phone.

But it feels like taking off your pants and farting. Why do you need accessories when you have a ready-made infrared thermometer? Why do you want to turn on your cell phone when you can check your temperature directly? Extra effort

The space in the mobile phone is inch by inch, and an infrared probe is forced into it. Personally, I really don't think it is necessary!

First, an APP without hardware participation is a rogue.

In order to truly measure accurately, hardware needs to participate, that is, professional hardware emits infrared rays to detect body temperature, and then feeds back the test results through the mobile APP.

If the mobile phone itself does not have these things, making such an APP can be said to be hooliganism, which is simply fake and meaningless.

Second, it is unnecessary to add hardware, but it will increase the cost.

Seriously, there seems to be such a demand in this situation. In normal times, this requirement is completely false, and no one will use this function at all.

On the contrary, if mobile phone manufacturers want to add this function, it will not only increase the cost, but also increase the cost of other R&D and design. Therefore, from a practical point of view, such a function is completely unnecessary in non-special periods, and no manufacturer will do so.

Third, it is also cheap to have professional equipment of this kind, such as forehead temperature gun.

In addition, if you really have this demand, just buy an extra temperature gun, which is more professional.

In fact, from the perspective of the market or users, we should also let professional equipment do professional things, rather than a mobile phone to do all the functions. In the future, mobile phones will become airplanes, cars, fishing rods, pens, kitchen knives and everything. This is unrealistic and unrealistic.

Mobile phone manufacturers are basically not very active in this function, because it is not just needed, and it will increase the extra production cost of mobile phones.

To talk about this problem, we must first look at the principle. Although some apps claim to be able to measure body temperature, they are not accurate compared with traditional thermometers. The principle of temperature measurement of these APP mobile phones is probably through a thermistor sensor (NTC), and the resistance changes with temperature. However, it is obviously unscientific to realize the thermometer with the help of the thermistor sensor inside the mobile phone without increasing other costs. Because the NTC inside the mobile phone generally only measures the chip temperature and battery temperature, it takes a long time for the machine to heat up, which is very inaccurate.

If you want to realize a real thermometer, you need to build a separate sensor (thermal sensor) in your mobile phone. In this way, the cost of your mobile phone will increase, and this function is not needed by every user.

At present, the common practice of some mobile phone manufacturers is that the development of mobile APP is only used to monitor body temperature data. For example, Xiaomi smart thermometer has no measurement function itself, but is only used as supporting management software. Therefore, most of these apps are only used for storage and data analysis.

There is no problem in developing this function, but the accuracy is terrible.

There are basically two kinds of infrared emitting units in mobile phones, namely distance sensors and grating emitters, which are used for face recognition. Not to mention the second one for facial recognition. If there is no camera to cooperate, the light will diverge and it is difficult to capture a stable infrared signal.

As for the distance sensor, the transmitter and receiver have not adjusted their accuracy, but they are basically stable to a certain extent. However, there is no need to force the intensity of light to be the same every time. As a measurement benchmark, it is naturally impossible to obtain accurate results, and there is also a lack of shielding for ambient light, which has serious interference.

To sum up, the results of the temperature measurement app made with the current mobile phone hardware configuration are completely incredible. Just have fun, there is no need to take it seriously.

With the hardware technology and software programming becoming more and more complex, mobile applications as self-diagnosis tools increased greatly last year. The latest product comes from Fraden Corporation, which recently announced that it has obtained the US patent of "Wireless Communication Equipment with Integrated Electromagnetic Radiation Sensor" due to the new infrared thermometer technology of its smart phone built-in module.

Basically, the technology they developed is a new type of infrared sensor built into smart phones, which enables users to measure the temperature of people or objects without any physical contact. Fraden has developed temperature sensor technology for smartphones.

Fraden's smart phone sensor can be used with the digital camera of the mobile phone to record the reading in less than one second.

Fraden sensors require users to point to the face of a person or object to record temperature readings. More specifically, the technology focuses on the use of non-contact infrared sensors, which can detect infrared signals naturally emitted by all surfaces. The user only needs to point the mobile phone at the face of the patient or object, and it will immediately record the internal temperature.

The sensor is installed in today's smart phone, and there is no substantial change to the phone itself: the whole infrared thermometer is packaged in a small ceramic patch module, and its working range includes 5 to 15? Infrared optical devices, infrared sensors, signal conditioners, ADC and I2C serial output circuits in the m spectral range.

It should be noted that the sensor can also be packaged in a TO-46 standard can with through-hole terminals. Further customization can reduce the camera height to 4 mm, and the cost depends on the quantity. The total incremental cost of components is between 1.65 USD and 2.50 USD.

Fraden sensors are very small and do not require any major design changes from the manufacturer. There is nothing outstanding that manufacturers need to consider. The sensor is located near the camera lens, so during temperature measurement, the camera can help locate the object that detects and measures infrared signals. In addition, the mobile phone containing this technology will look like a sensorless mobile phone.

Infrared thermal imager has two working modes: medical temperature and inanimate temperature. The former performs snapshot measurement, while the latter continuously measures and displays the temperature.

In order to measure the body temperature, the infrared lens should be located 0.5 to 6 inches away from the skin. The medical temperature range is 93 to108 F (the clinical accuracy required by ISO is 0.3°F).

In order to measure inanimate objects, the lens can be placed at the position of 0.5 inch to the required distance (all that is really needed is the surface area of the target object collecting infrared radiation), and the viewing angle of the camera lens is about 65438+05.

The sensor can detect the temperature range from-22 F to+400 F, so it can be used in kitchens (cooking, cold storage), bathrooms (bath water, shower temperature), schools (scientific experiments), industrial departments (automobiles, chemical processing, buildings) and so on.

Fraden sensors can be used for several different types of readings. However, the obvious target audience is parents with children, nurses, doctors, veterinarians, inspectors or others who may find it difficult to record the temperature of people, animals or objects.

"Most smartphone models are almost the same with each other, with only a small change," said Jacob, president of Vladen Company, an inventor with more than 50 patents and an expert in non-contact temperature measurement. Dr Vladen explained that the inventor of the popular thermal scanning ear thermometer. "Suppliers with breakthrough functions can use them daily in real life, such as reading children's body temperature and keeping a distance from competitors. We believe that this new patent can become an important competitive advantage for smartphone manufacturers. "

As far as the current situation is concerned, Fraden's sensor has reached the ISO standard and is ready to launch the technology immediately. In fact, the company has provided sensors to qualified companies with important business in the mobile phone market, so I think Huawei can try to cooperate with this company. As long as the camera is slightly modified, the performance of the camera will not be lost, and the infrared temperature measurement effect can be achieved, which is quite worth a try.

In this case, it can be realized on the mobile phone, but only if there is an infrared scanner on the mobile phone. If you don't have this function, you can't detect it with this APP.

So you have to keep up with the hardware.

If the new mobile phone is equipped with this function, it will be a new selling point.

Need mobile phone hardware support

However, there is an APP for measuring heart rate, which is smart and healthy. You can download and play.

At present, an infrared temperature measuring gun costs 400-500 yuan, which is inconvenient to carry around. Huawei's research and development strength is entirely possible to integrate the temperature scanning function into mobile phones.

Mobile phone and health, body getting news, social system publishing and life application are all developed in theory. Nowadays, mobile phones are all screens, and gradually mobile phones are gradually reduced to chips, implanted into human bodies, and service fees are charged regularly. Later, everyone can use it for free, and we only pay for in-app services. Later, the environment changed dramatically, and the electronic failure returned to the original.
