Researchers build blood pressure measuring app for iPhone, no need for the Galaxy S9's fancy sensor

Researchers build blood pressure measuring app for iPhone, no need for the Galaxy S9's fancy sensor
So, earlier this year, Samsung launched the Galaxy S9 and Galaxy S9+ with a new sensor added to them — one that measures blood pressure. And, after testing it, we concluded that it manages to get ballpark readings — nothing you should trust above dedicated medical equipment, but good enough to see if your readings are OK on a day-to-day basis.

Surprisingly, however, a group of Michigan State University researchers (Anand Chandrasekhar, Keerthana Natarajan, Mohammad Yavarimanesh & Ramakrishna Mukkamala) has figured out a way to develop an iPhone app that does the same with no need for any extra sensors. The idea is pretty nice, too — the user needs to place their finger over the front of their iPhone, trying to cover the selfie camera and apply a bit of pressure on the screen (as pictured). The app will then use readings from both the camera sensor and the variation of 3D Touch pressure felt on the display.

So, yes, we've seen some apps out there that use just the phone's camera sensor to read blood pressure. However, the use of 3D Touch here is innovative and seems to be beneficial for the readings' accuracy. According to the research, during testing, the app showed errors about 2mmHg higher than a finger cuff type device. In other words, it's not super-accurate, but using it on a daily basis to monitor your BP for any abnormalities is an achievable goal.

The team wants the app to be ready for prime time in 2019. Since iPhones are so popular, the researchers hope that they'd be helping for the improvement of a lot of lives.

Well, let us be the party-crashers. Apple is currently debating whether or not it should get rid of 3D Touch on its 2019 iPhones and going forward. Why? Pressure-sensitive displays are expensive to build, yet the majority of users out there barely care for or use 3D Touch. It's also not great that a ton of app developers haven't found a way to implement 3D Touch in their software products in any way that is meaningful or appropriate. So, Cupertino is considering scrapping the feature altogether. Well... that'd certainly throw a monkey wrench in the plans of Michigan State University team of researchers.

"not super-accurate" as the article said, and can't measure SpO2. Thanks for wasting your time anyway..

Just trying to make Samsung look bad again. The app is trash and I would take Samsung sensor over a app any day.

Exactly, those nasty guys at PhoneArena paid those researchers to develop this app for iPhones and thus make Samsung look bad again on an article, damn!.... #samsungtrollslogic #onlysmartpeopleuseandroid *rolls eyes

Why the hell are you using hashtags as if you're on a social media site? Besides that, your sarcasm has really become lackluster, although it never had any luster, to begin with. If you're going to troll, stick to acting like a mature adult and not some pre-pubescent child. I honestly expected more from you and other people who troll each other on this site.

I’m sorry I don’t fulfill your expectations I didn’t know I have to comply some requirements here about comments, the two trolls above are living on every apple article and I’m sick of people like them, I’m not supposed to have a decent conversation with people who I really don’t respect in the least because they go around thinking they can insult, bash and troll all they want on every apple article so I can’t have a “mature” response to those people, you definitely have to respond in kind, I have no intention to be respectful with android trolls on apple articles, I always try to shame them since I’m sick of them for dealing with them for many years even before I was an apple user

This is a discussion site. Anyone can post in any article they want to. This article is about apple and Samsung so, how in the heck am I trolling. Get over your self, lol Also why I said what I said is the writer could have simply said, Researchers build blood pressure measuring app for iPhone, but they had to say it with a dig at Samsung.

I’m sorry sissy but your excuse for trolling is not strong enough

If Samsung is mentioned in the article it is NOT trolling.

Your problem is that it's the exact same on both sides. Apple has just as many fanboy trolls. Its the nature of tech websites now, they get clicks by starting flame wars. No article can be published without a jab at someone or some thing. Samsung's sensor is far more accurate and a better solution, but this articles headline claims that this app can replace it. Its just phone arena stoking the flames. Everyone is over-polarized now. This article wouldn't have elicited a response at all if it was titled "Apple app can measure blood pressure." Of course, it probably wouldn't have received any views then either.

So you have to push your finger against the selfie cam? That's a bit inconvenient. Also does it monitor HR or SpO2?

Little by little we are coming closer to those awesome Tricorders.
