Fitbit Could Beat Apple To Game-Changing New Feature
Will a future Fitbit measure blood stress?

How’s your blood stress? If you wish to test it, you want a blood stress cuff. Whereas there are a number of smartwatches which might measure this, most notably Samsung, nearly all want you to calibrate your blood stress as soon as a month with a standalone cuff. Swiss firm Aktiia has a intelligent machine that measures it within the background (avoiding white coat syndrome) however you continue to must test it towards a cuff each 30 days. Aktiia provides a wireless-enabled cuff with the Aktiia band.
February 25 replace. Effectively, Fitbit might be able to measure blood stress earlier than Apple Watch, nevertheless it’s simply certainly one of a number of well being metrics Apple is making an attempt to guage. This week introduced information of one other of them, arguably more durable to realize than blood stress: non-invasive glucose monitoring.
Bloomberg’s Mark Gurman reported that Apple has hit “main milestones not too long ago” in creating a strategy to measure how a lot glucose is in a physique with out the necessity to prick the pores and skin to succeed in blood.
Whereas it’s by no means been publicly declared as an aspiration, I’m assured it’s one thing Apple is trying into, and this work—Gurman says it’s codenamed E5—appears to be transferring ahead apace.
Let’s not get carried away too quickly. He says there’s nonetheless “years of labor forward” however Apple now feels assured it may finally deliver glucose monitoring to market, it appears.
Even so, the prospect of not needing to jab one thing into your pores and skin or insert a patch into the pores and skin that must be changed each couple of weeks is a significant step ahead. It could profit everybody, diabetics, pre-diabetics or everybody else who desires to maintain observe of an essential physique metric.
Gurman says Apple’s non-invasive method will use optical absorption spectroscopy. He explains it this fashion: “The system makes use of lasers to emit particular wavelengths of sunshine into an space under the pores and skin the place there may be interstitial fluid — substances that leak out of capillaries — that may be absorbed by glucose. The sunshine is then mirrored again to the sensor in a manner that signifies the focus of glucose. An algorithm then determines an individual’s blood glucose stage.”
That is thrilling, and it’ll add to the appreciable well being capabilities of the Watch—when it arrives.
Now, a newly revealed patent reveals that Fitbit is working delivering a blood stress monitor in a smartwatch that doesn’t want the month-to-month calibration.
Really, there may be one different machine that does this, the Huawei D. It has a strap which inflates to measure your blood stress. It’s intelligent, however not fairly comfy sufficient to put on every single day.
Anyway, Fitbit’s new patent, noticed by GizmoChina, means that blood stress monitoring from nothing however a wearable is on the horizon, no cuff required. The place “a conventional blood stress cuff works by squeezing an artery with a various quantity of stress and ‘listening’ for the power of the affected person’s coronary heart beating towards that stress,” because the patent says, this machine works in a different way.
The patent reveals a wearable machine that has a stress sensor within the show. The person presses the sensor with their index finger, the place the radial artery is, inserting it sideways on the sensor. Directions will observe as to how a lot stress ought to be utilized and the heartbeat is measured by way of a photoplethysmogram (PPG) sensor that works optically.
This implies the sensor can divine systolic and diastolic readings, which is what makes up a blood stress measurement.
The patent says, “A person applies a variable stress to his or her blood vessels whereas a PPG sensor measures the amplitude of blood quantity pulses. The ensuing PPG sign and related stress information is used to calculate blood stress. Normal approaches to figuring out blood stress from oscillometric information can be utilized.”
So, will Fitbit implement this earlier than Apple will get spherical to it (the Cupertino large is believed to be engaged on including this functionality to a future Apple Watch)? Effectively, it’s laborious to know. Initially, deciphering correct blood stress data isn’t all the time simple, so—patent or no patent—Fitbit can have loads of testing to do earlier than it releases the characteristic in certainly one of its wearables.
And secondly, it’s not clear how superior Apple is in its work, although the corporate is understood for its perception that what’s essential will not be do it first however do it proper. However with so many firms engaged on easy, correct blood stress monitoring on the wrist, it’s starting to really feel like a case of when, not if, it’s going to arrive.
