Next Version of BP-monitoring Smart Glasses

Glabella (BP-monitoring smart glasses) records the stream of reflected light intensities from blood flow as well as inertial measurements of the user's head.

Glabella: Microsoft is developing the next version of its smart glasses that can work as a cuff-less, wearable and unobtrusive blood pressure measuring device.

The device 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, according to a paper published on Proceedings of the ACM Journal of Interactive, Mobile, Wearable and Ubiquitous Technologies.

Blood Pressure Cuffs - Are you Measuring your Blood Pressure Right?
Your health care provider may use a blood pressure monitor to measure blood pressure or suggest the use of home blood pressure monitor for a better BP control.

‘Microsoft is working on advanced BP-monitoring smart glasses. ’

From the temporal differences in pulse events across the sensors, this prototype derives the wearer's pulse transit time on a beat-to-beat basis.

A person's pulse transit time -- the time delay following each heartbeat as the pressure wave travels between two arterial sites -- provides an indirect measure of blood pressure, according to a report in IEEE Spectrum.

Although the glasses did well in a test run, they are not yet ready to hit the store shelves as the Microsoft researchers plan to evaluate the Glabella glasses in a clinical setting.

Blood Pressure Screening
Hypertension accounts for nearly 6% of deaths worldwide.

The team is also developing a next version of the device to make it more power efficient while making the frame smaller, the report added.

Currently, a small chargeable coin battery keeps the device running.

Blood Pressure Calculator
Blood pressure readings – what do the numbers mean? Use Medindia’s blood pressure calculator to check whether you blood pressure is at healthy level.

The aim is to shrink the device to such an extent that it could become a clip-on that works with anyone's regular glasses, the report added.
