Manzana has received patent approval for a highly accurate body temperature sensor within weeks of the launch of the Apple Watch Series 8 which, according to rumors, will have those capabilities.
Apple sent the proposal to the United States Patent and Trademark Officelater discovered by MyHealthApple. The title is “Temperature sensor in electronic devices“. Although the document suggests that it can be used on any computer, the illustrations shown refer to a Apple Watch.
The granted patent proposes an electronic component that stores a sensor and a differential probe. The system works by calculating the difference between the two ends of the probe. One touches the surface to be measured and the other the sensor. In such a way that, by calculating the difference in voltages, the sensor can correlate it with a specific temperature.
The patent explains in technical detail how the hardware component and thermal sensor work. And how it can be mounted on mobile devices in internal or external areas. In the latter case, it makes specific mention of how it can be located on the back of a smartwatch. It also makes mention of a high-precision absolute temperature sensor.”
The temperature sensor was in the Apple Watch Series 7, but it was delayed to the Series 8
Originally, the temperature sensor was going to arrive last year along with the Apple Watch Series 7. Apple scrapped the new feature after problems with algorithm development. This did not meet the necessary requirements prior to the technical validation testing process.
The problem with temperature measurement using the surface of the skin is that it changes significantly depending on the climate where the person is. Hence the need for an algorithm that compensates and produces results that are as accurate as possible.
Perhaps with the release of Apple Watch Series 8, which would be accompanied by a new design – although new rumors suggest that this will not be the case – is the right time to include a reliable temperature measurement system. This, in addition, would offer a significant amount of information to users. From the possibility of predicting diseases to helping couples with the process of conceiving children. It would also give more context during sleep phases and even detect if you have a fever. Although the latter, apparently, will not be available from the beginning.
It is true that granted patents do not guarantee new products or new functions. But the temperature sensor would be launched in September along with the new Apple Watch Series 8, according to Wall Street Journal as Mark Gurman in Bloomberg.
