News hardware Apple Watch 8: the most anticipated feature should finally be here
Over the years, the Apple Watch has become more and more a tool for monitoring your health, whether it’s when you play sports, when you fall or in everyday life. With the absence of a new health function on the Apple Watch 7, we could see a thermometer appear in the next version.
A thermometer in the Apple Watch 2022?
In 2021, the Apple Watch 7 comes out with a bigger screen that tickles the edges. And apart from a more resistant slab and the fast charge, it’s nothing on the health side.
Analyst Ming-Chi-Kuo had anticipated an Apple Watch 7 with a body temperature sensor, but not everything went as planned for the Cupertino company. The feature-related algorithm reportedly failed shortly before production began.
Apple abandoned body temperature calculation on the Apple Watch 7 due to an algorithm not up to standard just before the test phases. The Apple Watch 8 could be equipped with it if the algorithm meets Apple standards before production.
This would have aborted the project, and would have (perhaps) postponed it to the following year. This is not information retrieved directly by Kuo, but rather a guess based on the 2021 failure.
The Apple Watch, a real solution against the Covid?
The arrival of a feature like this first raises the question of precision. Apple knows how to do well and less well, but also knows how to improve. Today, the electrocardiogram of the Apple Watch is recognized for its reliability, while the calculation of oxygenation rate in the blood is not yet unanimous.
Tim Cook says it: Apple does not pretend to replace dedicated measuring devices, but wants to offer a practical solution for the user to get an idea of his general state of health.
Regarding the calculation of body temperature, we are of course thinking of the possible applications to fight against the Covid. Even as cases are down in France, caution is in order and we expect Apple to act as they did with FaceID, which now unlocks the iPhone even with a mask.
According to Kuo, it is difficult to reproduce the results of a thermometer that is placed under the tongue or in the ear, when the only accessible surface for a watch is the skin of the wrist. Hence the interest of an efficient algorithm that can overcome this obstacle.
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.

What is complicated with a body temperature sensor is that the temperature of the skin is very dependent on the outside and often varies. Hardware alone can’t do it, so you need an algorithm that holds up.
We know that Samsung is also on the job to implement a thermometer in its Galaxy Watch 5, but Kuo is not very optimistic and does not see the Korean firm succeeding in making the algorithm work for their next connected watch. To see if Apple manages to get ahead of them.
