Apple Watch Patent Shows an Air Pump for Monitoring Accurate Blood Pressure
Apple also seems to be creative in development. Apple was criticised earlier for not having adequate health sensors in the watch series. A new patent for the popular smartwatch proves that. According to this, Apple patented the idea of an attachable blood pressure sensor that works with compressed air.
Earlier this year, it was reported that Apple had rolled back plans to measure blood pressure with the Apple Watch until 2024. After a few tests, there should have been several issues. As a new patent shows, Apple has been looking for creative ways to measure blood pressure with the smartwatch ever since.
Apple Watch with an air pump?
The patent filing suggests that the Cupertino-based company could use a separate device to measure blood pressure in future wearables. The sketch shows a compact device placed between the bracelet and the back of the wrist. It consists of stacked components, including a liquid-filled sensor that is said to help determine the pressure changes, as well as multiple sensors.
The patent also mentions an inflatable layer and an air pump intended to compress blood vessels. This function is comparable to a classic blood pressure monitor, in which the blood vessels in the upper arm are compressed with a cuff. However, Apple’s solution is much more complicated and involves small mechanical and electronic parts. The pending patent does not mean that this technology will actually be used in future Apple watches. In general, Apple is unlikely to use such a curious solution to measure blood pressure.
In addition, there are already smartwatches such as the Galaxy Watch 4, which can measure blood pressure without a pump mechanism. But it’s exciting to see what creative ideas the Apple engineers have, isn’t it?
