These Glasses from Microsoft Can Monitor Your Blood Pressure

  •  Microsoft is branching out into healthcare by launching a pair of eyeglasses that can monitor blood pressure.
  • The tech giant filed a patent for the eyeglasses called Glabella as competitors including Apple have done so in the past on potential groundbreaking invention.
  • Microsoft’s prototype medical device is designed for easier use and more accurate reading than a conventional inflatable cuff.

Microsoft has filed a patent for its newest innovative product—a wearable set of eyeglasses capable of monitoring blood pressure more accurately than a traditional BP monitor. The product, called Glabella, has the capability to record physiological data of the user.

Microsoft’s rivals Apple, Amazon, Google and Samsung, have all filed patents for their newest inventions so others cannot reproduce or sell them. With a patent, these products with potentially groundbreaking technology are protected. Google has filed a patent for eyeglasses with a heart rate monitor.

Microsoft software engineers Christian Holz and Edward Wang developed the prototype medical device to continuously track blood pressure.

“Our glasses prototype incorporates optical sensors, processing, storage, and communication components, all integrated into the frame to passively collect physiological data about the user without the need for any interaction,” Holtz and Wang wrote on the Microsoft website.

Glabella also continuously records the stream of reflected light intensities from blood flow as well as inertial measurements of the user’s head, according to the engineers.

“From the temporal differences in pulse events across the sensors, our prototype derives the wearer’s pulse transit time on a beat-to-beat basis,” they added.

On their patent application, Microsoft states that Glabella measures and stores the user’s pulse waves, repeatedly, at three different sites on the face and uses inertial sensors and a processing unit that compares the continuously recorded pulse waves – to obtain the user’s pulse transit time – the delay between the moments at which the blood ejected from the heart reaches the three sites.

The sensor can likely serve as a socially-acceptable capture device, one which would require no user input or behavior changes during regular activities and still collect data that would inform physicians and patients, according to Microsoft.

Medgadget wrote on its website that Glabella has the potential to identify the activities, diet, drugs, and other factors that influence an individual’s blood pressure because of its continuous “measurements thousands of times a day.”

Microsoft has already tried the Glabella with four volunteers continuously using it for five days, and the device has shown a pretty good correlation in estimating systolic blood pressure compared to a standard cuff, according to Medgadget.
