Selfie Videos Can Be Used To Measure BP?

Published

on

BP can be measured using selfie videos. Could you have ever imagined? No right? But well, it seems like this may be possible. In good news for people who have blood pressure (BP) problems, monitoring BP might one day become as easy as taking a video selfie.

Researchers have tested a technology called transdermal optical imaging. Seems like, this measures blood pressure by detecting blood flow changes in smartphone-captured facial videos.” This study shows that facial video can contain some information about systolic blood pressure.” This was carried out by said researcher Ramakrishna Mukkamala. He is a professor at the Michigan State University.

Ambient light penetrates the skin’s outer layer.  As a result, this allows digital optical sensors in smartphones to visualize and extract blood flow patterns. Transdermal optical imaging models can use this to predict blood pressure.

The Study

For the study, the research team measured the blood flow of 1,328 Canadian and Chinese adults. Most importantly, it did so capturing two-minute videos using an iPhone equipped with transdermal optical imaging software.

Consequently, the researchers compared systolic, diastolic and pulse pressure measurements captured from smartphone videos. This was done using a traditional cuff-based continuous blood pressure measurement device. Next, the researchers used the data to teach the technology how to accurately determine blood pressure and pulse from facial blood flow patterns.

It’s interesting to note that the device measures BP according to international standards. However, researchers videoed faces in a well-controlled environment with fixed lighting. Hence it is unclear whether the technology can accurately measure blood pressure in less controlled environments, including homes.

Also, the study participants had a variety of skin tones. But the sample lacked subjects with either extremely dark or fair skin. Thus, we can’t tell how successful this device will be. But if it is any good, it’ll be one smart invention!

Chandrayaan-2 Spins History In Lunar Orbit

Published

India’s spacecraft to the moon Chandrayaan-2 successfully entered the lunar orbit on Tuesday, clearing a crucial move for it to land on the moon’s surface on September 7.

The spacecraft will hover around the moon’s orbit for the next few weeks, before it is slowly lowered onto the lunar surface. Chandrayaan-2 is an integrated spacecraft comprising an orbiter, a lander – Vikram named after the father of India’s space programme Vikram Sarabhai and Pragyan, a rover that will roll out out once the lander touches ground.

India’s first moon mission Chandrayaan-1 suffered damage to a few instruments after it faced issues with the heat shield of the spacecraft on entry into the lunar orbit. Space scientists had attributed to the lack of adequate information on the heat generated due to friction when entering the moon’s orbit, a crucial data the US declined to offer. This time around, Isro officials had enough data from its first mission to make the lunar entry smooth.

“We did what all humanly was possible, but at the same time since it is new mission and it is a terrifying moment for us,” said K Sivan, Chairman of Isro.

A series of orbit manoeuvres will be performed on Chandrayaan 2 spacecraft to enable it to enter its final orbit passing over the lunar poles at a distance of about 100 km from the moon’s surface, Indian Space Research Organisation said.

“The landing day is fixed and the location of the Moon is fixed, but our launching day delayed to achieve the same landing day, we worked on the time based on that,” Isro chairman K Sivan said. “After landing images will be made available by the Rover”.

A little while ago, we found out that Apple might launch the next iPhone on September 10. Now, however, the news suggests that Apple might launch the next Apple Watch along with it. According to a recent report by iHelp BR, the Apple Watch will come in ceramic and titanium models. Apple’s next series of smart wearables will come in 44mm and 40mm sizes and run watchOS 6 right out of the box.

The report gives out information about the two new materials that next iWatch will come in. These reports are based on a couple of animations found in the Apple Watch’s initial setup process.

The copy in the leaked animation reads, “44mm titanium case. Designed by Apple in California.” It then shifts to, “44mm ceramic case. Designed by Apple in California.”

Apart from a tiny Apple logo in the centre of the animation, no other detail is revealed in the animation.
