Blood pressure e-tattoo promises continuous, mobile monitoring:

Blood pressure is one of the most important indicators of heart health, but it's tough to frequently and reliably measure outside of a clinical setting. For decades, cuff-based devices that constrict around the arm to give a reading have been the gold standard. But now, researchers at The University of Texas at Austin and Texas A&M University have developed an electronic tattoo that can be worn comfortably on the wrist for hours and deliver continuous blood pressure measurements at an accuracy level exceeding nearly all available options on the market today.

[...] Graphene is one of the strongest and thinnest materials in existence, and it is a key ingredient in the e-tattoo. It is similar to graphite found in pencils, but the atoms are precisely arranged into thin layers.

[...] The device takes its measurements by shooting an electrical current into the skin and then analyzing the body's response, which is known as bioimpedance. There is a correlation between bioimpedance and changes in blood pressure that has to do with blood volume changes. However, the correlation is not particularly obvious, so the team had to create a machine learning model to analyze the connection to get accurate blood pressure readings.

In medicine, cuff-less blood pressure monitoring is the "holy grail," Jafari said, but there isn't a viable solution on the market yet. It's part of a larger push in medicine to use technology to untether patients from machines while collecting more data wherever they are, allowing them to go from room to room, clinic to clinic and still get personalized care.

    You care. You are ALSO clearly disturbed by my overpowering & OUTSMARTING you! You are having a shit fit that I am IMPOSING MY WILL over your bullshit downmods AND crapping all over you letting YOU do THAT to yourself due to your errors I exposed DALEK [] and you ARE the "schizo" you PROJECT you are trying to project that onto me - how? I don't keep a FAKENAME like YOU DO, I post as myself (AC but I "id" myself signing off as "APK" in my posts) - YOU by contrast "play batman" lol, & post UNIDENTIFIABLE AC anonymous to HIDE it IS you, Dalek... after all, who ELSE would care enough to FOAM @ THE MOUTH like you are now? Nobody else would but YOU, Dalek!

    * :)

    (Yes folks - it is THAT EASY to show you that I AM BEYOND YOUR CONTROL & yes, that I am IMPOSING MY WILL ON YOU, running you DRY of your ABUSED "downmodpoints" CENSORSHIP - I override it AND also OUTSMART THE HELL out of WANNABES like Dalek the fakename).


    P.S.=> Yup, per tradition? You're MAKING me just HAVE to say it again: THIS? This is just "too, Too, TOO EASY - just '2ez'" & it ALWAYS IS vs. no-mind do NOTHING ever in the computer sciences wannabes... apk

    You should smoke some weed man, or try tincture. I hear it's legal now by you. Dry herb vaporizers are good (heats herb to 420°F to vaporize oils), but avoid the disposable pen types. For tincture look for MCT oil, and CBD might also help.

    It took me a few tries before I found a tincture that got me the high I like. Not all highs are the same, but there might be a high that could help you mellow out.
