The Apple Watch Series 8 would be able to take your temperature

According to information from analyst Ming-Chi Kuo, Apple would integrate a measurement of body temperature on its Apple Watch Series 8. Opposite, Samsung would have trouble developing sufficiently reliable algorithms for this measurement.

For several months, there have been insistent rumors of new health measures on the next generation of connected watches from Apple, the Apple Watch Series 8.

We know that Apple is actively working on the development of several new features that should arrive over the next few years. In addition to heart rate, blood oxygen saturation or electrocardiogram, Apple would include including a system to measure blood pressure or blood sugar levels. However, these two novelties should not arrive this year. The most anticipated novelty for 2022 should indeed be the arrival of a thermometer on the Apple Watch Series 8.

This Sunday, analyst Ming-Chi Kuo, usually very knowledgeable about Apple’s plans, posted a series of tweets to provide an update on Apple’s progress in this area.

The challenge in implementing precise body temperature measurement is that skin temperature quickly varies depending on outside environments. A smartwatch can’t support core temperature measurement in terms of hardware, so it needs an excellent algorithm to work together.

“Apple canceled temperature taking on Apple Watch 7 due to algorithm flaws prior to validation and testing last year. I believe the Apple Watch 8 in the second quarter of 2022 could incorporate body temperature measurement if the algorithm meets Apple’s high requirements before mass production”indicates the analyst of TF International Securities.

Body temperature probably at Apple, but not yet at Samsung

It must be said that taking body temperature at the wrist is particularly complex. Indeed, the measured temperature will in particular be influenced by the immediate environment. It is therefore difficult to get an idea without going through algorithms capable of compensating for the outside temperature. Huawei, for example, already offers temperature measurement on its latest connected watches. However, it is a measurement of skin temperature and not body temperature. A difference that can be more than 5 degrees. However, for the measurement of a fever for example, this difference is far too high to be able to draw reliable data. “The challenge in integrating accurate body temperature measurement is that skin temperature varies rapidly depending on the external environment. A watch can’t support body temperature just with hardware, so it needs a great algorithm to work”says Ming-Chi Kuo.

The analyst indicates that Apple would not be the only manufacturer of connected watches on the spot. According to his information, Samsung would also like to offer a measurement of body temperature on its future Galaxy Watch 5. However, the Korean manufacturer would also have trouble offering a reliable measurement in the absence of a sufficiently effective algorithm. According to Ming-Chi Kuo, the Samsung watch would not yet be able to offer such a measure this year.
