Reinventing clinical grade Blood Pressure Monitoring by optical sensors

aktiia, a Swiss company based at Neuchatel and Zürich in Switzerland has achieved a breakthrough in the way the blood pressure is monitored. Backed by nearly 15 years of research, this medical startup company has patented the technology for continuous blood pressure monitor, 24/7, without interrupting the daily routine.

The technology combines information from embedded sensors in commonly worn wearables for heart rate monitoring with clinically validated software algorithms to monitor individual blood pressure. The optical sensor in the wearable picks up the signals from the pulse waveform, analyze and modulate it to be displayed as blood pressure reading.

The Optical Heart Rate Monitoring technology (OHRM), so commonly used in smartphones and bracelets was pioneered by the Swiss Research and Technology Organization (CSEM) way back in 2004. The OHRM relied on the so-called Photo-Plethysmography principle (PPG).

The aktiia team released that the PPG technology applied at the wrist holds much more information than just measuring the heart rate. Under the able guidance of the co-founder and CTO, Josep Sola, the team identified and extracted the additional information from the pulse waveform at the wrist, resulting in the birth of the Optical Blood Pressure Monitoring (OBPM) technology.

The technology is backed by over 30 peer-reviewed publication and numerous clinical trials in acute and low-acute settings.

aktiia has recently raised CHF 4 million in seed round to commercialize its groundbreaking, cuffless, blood pressure monitoring technology. The partners include Silicon Valley-based TransLink Capital, Swiss-based Redalpine, and other international angel investors.

aktiia plans to embed the algorithms in non-medical third-party wearables for daily tracking the blood pressure trends for preventive purposes, as well as in aktiia’s medical grade wearable for the continuous monitoring of blood pressure in patients with hypertension.

“This technology is a quantum leap in the fight against hypertension and will revolutionize the way we look at blood pressure,” stated Michael Sidler, Co-Founder, and Partner of Redalpine.

“TransLink has always been on the forefront of wearable technologies, and we are constantly on the lookout for pioneers. We are very excited to be a part of what will be a healthcare game changer,” said Eric Hsia, Managing Director of TransLink Capital.

  1. The opposite effect, known as "masked hypertension," can also occur—some people have normal blood pressure readings at the doctor's office but high blood pressure most of the rest of the time.

  2. First, I want to complement this site administrator for creating this platform I frequently get cold sores(which lasts for 5-6 days on my lips and its painful both physically and mentally) .. As a bodybuilder, I basically get outbreak due to the daily pressure and heat in the body.. Recently I stumbled upon my salvation. I found a herbal remedy to cure hsv completely, in just 4weeks ..

    I got to know about Dr Utu after seeing a lady's testimony online. I reached the doctor and I ordered for herpes herbal medicine. He sent the herbs to me and I started making use of them. In just 2days, the cold sores are cleared. 4weeks after medication, I went to the hospital for test of cold sores and it was completely NEGATIVE.

    By following every prescription, i was able to cure my cold sore in less than 4weeks. 100% natural herbs no after effect.
    Note: Please do let others know if this work for you.
    The doctor's email is drutuherbalcure@gmail.com
    Note : follow all instructions accordingly..

    If you are sure that you have benefited from this African herbs be courageous to inform others.
    Thanks in advance
