from Claus Ludewig –
In a patent application, Apple has explained how blood pressure can be measured with a future Apple Watch.

The Apple Watch Series 7 has been available in stores since October 15, 2021. If you want, you can get the smartwatch in size 41 millimeters for 400 euros. The successor called Apple Watch Series 8 is expected this year. The new smart watch is said to have a body temperature sensor. However, it is not yet possible to measure blood pressure with an Apple Watch. In a patent, the manufacturer explains how it could become possible in the future Determine blood pressure using a smartwatch.

No optical sensor for measuring blood pressure on the Apple Watch

Instead of an optical sensor, the blood pressure should be measured by compressing the arm. In conjunction with an air pump, a sensor is pressed against the user’s skin to determine the blood pressure in a blood vessel. There is a liquid in the sensor itself, so that the blood pressure is measured via the liquid volume. According to the patent, a special bracelet is required to use this type of blood pressure measurement. An Apple Watch with a blood pressure measurement could not be available until 2024 at the earliest.

First of all, the Apple Watch Series 8 will probably be available in autumn 2022. The sensors are said to only be able to detect body temperature and warn of increased temperature. There should not be any specific measured values ​​for body temperature, so that Apple can save itself the time-consuming and expensive approval from the FDA. Consequently, you will not be able to measure fever with the Apple Watch Series 8.
