Nowadays, science and technology are becoming more and more advanced, and methods for measuring body temperature are also innovating. In ancient times, if you wanted to measure body temperature, you could only feel it with the back of your hand. Later, thermometers appeared, and now you can measure body temperature on your phone, which was unimaginable in the past. So, is it accurate to use fingerprints to measure body temperature on your phone?
Is it accurate to use fingerprint to measure body temperature on a mobile phone
Mobile phones need to have temperature sensors to measure body temperature and see if the user has a fever. A temperature transducer refers to a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core part of temperature measuring instruments, with a wide variety of types. According to the measurement method, it can be divided into two categories: contact and non-contact. According to the characteristics of sensor materials and electronic components, it can be divided into two categories: thermistor and thermocouple. It is still relatively accurate.
What is the correct method for measuring body temperature
There are three commonly used methods for measuring body temperature: oral measurement, axillary measurement, and anal measurement. The thermometer used for oral measurement is called an oral thermometer, the thermometer used for axillary measurement is called an axillary thermometer, and the thermometer used for anal measurement is called an anal thermometer. Regardless of the measurement method used, the mercury column in the thermometer should be shaken to below 35 ℃ before measurement.
Although mobile temperature measurement has been achieved and the method is still very scientific, more people may still prefer or prefer to use the old method of measuring body temperature, which is a thermometer. This is partly because the principle of measuring body temperature with a thermometer is more direct and easy to understand, which makes people more trust it. On the other hand, it is also because of the habits developed over the years, indicating that the promotion of new technologies still requires some time.
