Wearable physiological monitoring
I am proud to be one of the scientists and engineers who made the Biovotion Vital Sign monitor possible. It has been a long way to this technology, but it was an exciting journey and quite a learning curve. And there is still a plenty of development to be done, but we are very motivated by the results of clinical studies performed with our device and the feedback from people who are using the device.
We have been able to achieve motion-tolerant robust monitoring of the Heart Rate (HR) and blood oxygenation (SpO2). One can go to the gym with this device and still get continuous and reliable readings.
We have published some steps of our learning (see below) and more manuscripts are in preparation.
In a meantime, I am tracking my daily life with the prototype device and further working on the algorithms. Some of the data I post in my blog.
