Apple Watch Series 8: Insider Teases Spectacular Upgrade – Forbes

Apple Watch Series 7 recording an ECG. Will Series 8 offer body temperature monitoring, too?
Apple’s health monitoring capabilities are found in multiple products but none more than the Apple Watch. New tweets from the highly reliable Ming-Chi Kuo from TFI Securities indicate that a new sensor may be about to arrive.
According to the analyst, body temperature sensing could arrive with Apple Watch Series 8. If there’s a ring of déjà vu about this, it’s because the sensor had been predicted for Apple Watch Series 7.
But, Kuo says, “Apple canceled body temperature measurement for Apple Watch 7 because the algorithm failed to qualify before entering EVT stage last year.”
EVT stands for Engineering Validation Test, by the way. So, the intended inclusion failed for software reasons, if Kuo is correct.
This makes sense. It’s one thing to have a sensor which can look out for particular properties and another for the software to be able to accurately interpret what’s found. Kuo explains: “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.”
But there’s better news. Kuo says that for Apple Watch Series 8, this fall, Apple could “take body temperature if the algorithm can meet Apple’s high requirements before mass production.” Time is ticking then, which seems appropriate given we’re talking about a watch.
If rumors were right that the feature was planned for last year but Apple wasn’t happy enough with how things were going for it to be included, then surely another year would be enough for it all to fall into place? Perhaps, but Apple is notoriously perfectionist about these things. It won’t include something that doesn’t work.
And the problem isn’t just limited to Apple. Kuo claims that Samsung is working on a body temperature feature for its next Galaxy Watch smartwatch, predicted for the second half of this year. The algorithm is the issue here, too, it seems.
Body temperature monitoring would be a logical next step for the Apple Watch, promising a greater understanding of stress levels, for a start.
With four months before Apple Watch Series 8 is expected to arrive, there’s time for more leaks to leave us better informed.
