Wearables that measure blood pressure from unusual areas are currently being developed by Apple, Samsung, and now Microsoft.
BPMs normally come in one of two forms: those that are worn on the upper arm, and those that are worn on the wrist. This is true of both smart and classic BPMs. Although blood pressure readings collected at the wrist may not be as reliable as those taken at the upper arm, both of these monitors utilise the inflatable cuff technology. This is due to the fact that the arteries in your wrist are thinner and do not run as deeply under the skin as those in your forearm.
However, a number of businesses are exploring the possibility of relocating their operations to other areas. At CES 2018 earlier this year, Omron demonstrated HeartGuide, a sphygmomanometer that is the size of a watch and claims readings that are just as accurate as those obtained from devices worn on the upper arm. The arrival of the device is anticipated for the fall of 2018.
Tech behemoths are also making their way into this sector. Apple has just received a patent for a watch that automatically inflates itself to monitor blood pressure. It comes with a cuff that has sensors built into it, and the sensors are combined into a collection of very small airbags. The upcoming Galaxy Watch from Samsung is another possibility. It is said to be able to monitor your results by shining polarised light on them and then detecting the strength of the light that is dispersed after the light has been scattered.
The development of a blood pressure monitoring gadget by Microsoft, however, may have sent the company down the most peculiar path of all. A study written by Christian Holz and Edward Wang of Microsoft Research disclosed the existence of the prototype.
The glasses come equipped with optical sensors that are discretely hidden within the frame and go by the name Glabella. From that point on, they continuously measure pulse waves at three separate sites on the user’s face, and then they calculate the time and frequency between these spots and the heart in order to determine blood pressure. The glasses are also capable of collecting data on physical activity, allowing them to function as a tracker of activity around the clock.
It is interesting to note that the accuracy of the sensors has only been demonstrated while measuring systolic blood pressure. When the heart is actively pumping blood throughout the body, this is the value that represents the blood pressure at its highest point. Both readings have their applications, despite the fact that systolic blood pressure is often believed to be more significant than diastolic blood pressure. It is more accurate to determine your risk of suffering a stroke or heart attack based on your systolic blood pressure.
A high diastolic blood pressure, on the other hand, is detrimental to the health of the heart since it indicates that the heart is not relaxing as much as it should, which can lead to various cardiovascular issues.
According to the report, a test was carried out in the real world, and the results demonstrated that the technology was reliable. It is not totally clear whether we will actually see a consumer version of this device but it seems likely. Patents are frequently granted to manufacturers for technologies that are never developed beyond the planning stage. Patents make it harder for competitors to enter the market and steal ideas from others.
