  • Crowdfunded product Muse Ring One claims to be able to monitor blood pressure
  • The Muse team says it’s analyzed over 4,000 test users to identify the correct way to measure BP
  • If true, it’ll have cracked LED-based BP measurement before many smartwatches

Whether it’s fall detection, an ECG, blood oxygen monitoring or running third-party apps, the best smartwatches grow in scope as personal health each year (or, if it’s an Apple Watch, they do the opposite and wind back features due to a patent dispute!).

More Information:

Does Ring One measure Blood Pressure?

Yes, Ring One is the first smart ring to do cuff-less blood pressure measurements. It uses contextual awareness to choose the best time to measure your blood pressure and gives you accurate readings. The two optical PPG sensors work together in perfect sync to get the best signal. The algorithms use your height, weight, age and gender to estimate your blood pressure based on the signal received by the PPG sensors.

One wearable tech company claims to have cracked it. It’s not Apple, Google or Samsung that’s leading the charge, but a company called Muse Wearables in India, which hopes to release the best smart ring for blood pressure monitoring.

So it has done what Apple, Google, or Samsung haven’t.
And what Aktiia hasn’t been able to do (without calibration).
No published papers.
No CE certification.
It is an Indiegogo campaign.

Chicago biohub publishes its first research, discovering way to continuously monitor inflammation

The study, co-led by Northwestern University researchers at the Chan Zuckerberg Biohub Chicago, was published this week in the peer-reviewed journal Science.

The sensors were implanted in diabetic rats to track changes in certain proteins that can indicate inflammation. While it’s already possible to measure changes in the proteins through periodic blood or urine tests, the sensors could provide a way for doctors and scientists to continuously measure the changes as they occur.

Interesting - anyone know how it compares to Elemind out of MIT: How to get a better night's sleep by hacking your brainwaves (NewScientist) - #27 by Neo

Both seem to have done real clinical trials that show that they work, here is from Somnee, link above and thread have data for Elemind

I’ve ordered a Somnee. I will report if it works for me.

@cl-user Cool. Thx. Did you compare vs Elemind before making the decision?

#48

I’ve chosen the Somnee because you don’t keep it during the night. It’s just a 15 min stimulation before sleeping and you remove it for the night.
Also the Elemind study was about sleep onset which is not an issue for me while the Somnee one was sleep onset + sleep quantity. Both studies are underpowered and underwhelming though.

Thx for color. I like that Elemind is through sound waves instead of electric signals.

The wear for 15 min vs all night has pros and cons on both sides - especially if the eeg reading works as well as both of the companies claim, being able to respond to state of sleep at point during the night might be quite powerful

Look forward to hearing about your experience.

Hypothetically one could do a Brian Johnson type of more is better approach and each night first use Somnee and the switch over to Elemind.

(I had ordered Elemind way before hearing about Somnee, and it actually just arrived - so hope to start trying it next week or so).

@Joseph_Lavelle think you were optimizing sleep? Have you looked at either?

@adssx - the increased sleep might also help with neuroprotection and against depression

Thanks Neo.

Do we have a study comparing the efficacy of Somnee or Elemind to a placebo/sham device?

#51

I have had some better sleep hygiene recently or it has been something else, but feels like I’ve slept amazing, feel really energized in the morning. I don’t know what to track part of sleep, I remember in the past that my Oura scores hasn’t really reflected this. I wonder if accuracy is too low or the composite score is not good.

So it’s worthwhile to optimize to feel energized in the morning and early day without stimulants I think and that’s the marker of good sleep. I tried drinking a cup of green tea on top but then I just felt like a mouse on cocaine. Preventing decline of this with age is also super important. I would trade a lot for this, and I suspect this to have benefits on top that aren’t directly experienced… (i.e neuroprotection or depression risk).

I think one of the Somnee trials might have been like that - “fixed stimulation”:

IMG_9388
IMG_93881052×663 49.5 KB

They also did one vis a vis melatonin and vs prescription sleep meds so that should also control for some/most of the placebo effect

Elemind was like 6 moths since I looked at so can’t remember their details, but quick skim suggests

“During the Sham week, the headband silently recorded EEG.”

It was a cross over design - so that helps too

But the trials overall are small

You’re right: “Our controlled sleep lab studies were conducted with adult participants, age 30-70. Each participant had at least two sleep sessions, one of which was a sham session (like a placebo – a session where they slept without the stimulation we were evaluating). Sleep activity was recorded using laboratory-grade EEG and EKG systems, and was scored by a certified polysomnography technician, using the same approach as any medical sleep lab. […] Personalization enables faster sleep onset. Data from a sham-controlled real-world study, n=55 participants, 1,800+ nights.”

Still a trial trial. I can’t wait to hear your feedback!

(That’s better than the comparison to metformin because I think the placebo effect is stronger for a big device you put on your head vs a simple pill. And there’s also the meditative effect of taking 15 minutes every day to do nothing before going to bed, whether the device is active or not.)

I just posted in a different thread that we are in the market for a new blood pressure monitor

Are any of these new gadgets ready for prime time? (Rings/watches/etc)

If something does more than just blood pressure, that is a bonus

Open to hearing anyone’s top recommendations, please!!

impressive reveals of CES 2025 so far:

A 360° AI-powered body scanning health mirror that can scan your heart, weight, and metabolic health

The mirror aspect, which provides a 360-degree scan of your body, looks at your weight, heart and lung health and can even take an electrocardiogram. The Omnia also has a base you stand on (the scale part) that reads health metrics and biomarkers that include blood pressure, heart rate, Vo2 Max and can also read your sleep quality. Using an AI voice assistant, the Omnia can make recommendations based on this data. For example, Omnia may tell you to get more steps in or schedule a doctor’s appointment. It also claims to track metabolic health, so it can read your muscle-to-fat ratio, visceral fat, weight trends and more.

Although Withings says the Omnia won’t be on the market any time soon since it’s currently in development, the brand confirmed it will add some of the newer features to existing products later this year.

Cardio Check-Up is an in-app service for heart health that enables users to receive detailed feedback on their cardiovascular health from board-certified cardiologists within 24 hours.

Housed within Withings+, the company’s subscription-based health improvement service, Cardio Check-up, goes live on the first day of CES 2025 (January 7, 2025) and is powered in the U.S. by Heartbeat Health and by DPV Analytics in France, Germany.

Cardio Check-Up is compatible with all current and future Withings devices with ECG capabilities. These include the hybrid smartwatches ScanWatch, ScanWatch 2, ScanWatch Nova, and the new ScanWatch Nova Brilliant, as well as the Body Scan connected scale, the Move ECG and BPM Core connected monitors, and the groundbreaking 4-in-1 MultiScan checkup device, BeamO.

Other new health tech:

The Hormometer provides actionable insights into critical hormones, beginning with cortisol and progesterone. Imbalances in hormones can have wide-ranging effects, contributing to issues such as chronic stress, fatigue, male and female infertility, weakened immunity, weight fluctuations, disrupted sleep, poor heart and bone health, and accelerated aging.

The Echo Flask features an industry-leading 12-ounce capacity, reducing refill interruptions while delivering consistent hydrogen water. With its advanced proton-exchange membrane technology, the flask achieves a hydrogen concentration up to 8.0 ppm—higher than any hydrogen bottle in the industry. https://echowater.com

A lot of devices, for sure. However, being old, I have a very different approach to such news. I have seen too many devices come and go, wild claims and poor delivery. Most recently, I had a disastrous experience with a big company (Abbott) CGM device - you’d think it being a big established pharma company would assure some kind of quality. But my CGM was off by 30-40 points, rendering it 100% useless (plus terrible support what with a very inferior app). And now we’re talking about often brand new companies coming out of the woodwork with “amazing” devices? I’d wait with the enthusiasm until the product actually comes out and actually delivers on the promise. Otherwise, I see this as not much more than the prospectuses with which biotech companies try to encourage investors - a LOT of promise and low to very low odds of delivery. My only response to any of these would be: “call me when it’s out, and when it’s working verified by a lot of independent customers” - until then, I personally would hardly even waste time reading about them, because through the decades I’ve seen this movie too often - most of the time the product either never comes out or doesn’t work as advertised. Of course, I wish them the best, after all, we’re all prospective customers and we’d like nothing more than for all this stuff to be available and reliable - so we’re definitely pulling for them to succeed! YMMV.
