WMe2 - health tracker that takes accurate readings
Devices Medgadgets / / December 19, 2019
In our editorial sent to test the company's development Rooti Labs - WMe2 biosensor that comes close in function to a full-fledged medical devices.
He can do everything that they can fitness tracker counts steps, calories burned, measures the heart rate, helps to monitor the amount of sleep.
And he knows a lot more: calculates the blood pressure through the propagation velocity of the pulse waves and estimates the state of the autonomic nervous system in terms of variability of heart rhythm.
All measurements are performed using a small sensor size 18.5 × 46.5 × 8.5 mm and weighing 15.8 g
It can be worn as a bracelet, which supplied the straps are provided in two colors: white and black. A can be used in conjunction with kardiopoyasom. In edition came sensor, which can be via dongle fasten the female sports top. Also in the package includes instructions and battery charger.
WMe2 controlled through an application on your smartphone. Tracker is compatible with iOS 8 systems (iPhone 5+, iPad 3+), Android 4.3+.
bracelet Diet: calories, steps, distance, dream
The mode sensor bracelet has several functions, working as a digital clock, pedometer, calorie counter. Moreover, the sensor detects the distance traveled. To view the current data, it is sufficient to press the side button or double-tap sensor. Long press on the button includes a sleep mode locking.
All information after synchronizing with the smartphone are entered in the application in which you can specify the target: the desired amount of sleep, steps and time for training.
It all know how fitness devices, this feature WMe2 not the case.
band mode: cardiointervalogram
With the sensor can measure the pulse pressure and to estimate the age and balance of the autonomic nervous system.
The autonomic nervous system is responsible for the work of the unconscious body. It makes the heart beat, it reduces the smooth muscles of the bodies, she commands the release of hormones and so on. It consists of the sympathetic and parasympathetic divisions. First Division accelerates the entire system, the other slows.
Sympathetic section includes a mode of "fight or flight", if the external environment is unfavorable for the residence, there is a shortage of nutrients, inability to relax, overexertion or lack of movement. You can guess that a couple of points could be included in the list of each first. For us, this means that the body is in a constant state of stress.
In a healthy young body work departments balanced. In diseases and during the aging sympathetic section begins to take over, which is why in the end the blood circulation gets worse, the person gets tired much faster, disrupt the function of all organs. Assessment of the state of the ANS helps determine how your body is exhausted.
To get the data you need to keep WMe2, holding it between thumb and forefinger. Within 75 seconds, the device evaluates the rhythm with which your heart beats, and after processing the information indicates how many years of your internal regulation system and which department dictates your body that do.
If the arrow on the indicator declined balance to the left, and the balance is in the range from 0.8 to 4, then you are normal: the dominant influence of the parasympathetic division. Deviations indicate problems.
Left - an example of the results obtained in the morning. Right - in the evenings. The age difference VNS - 30 years. All the powers given Layfhakeru. :)
It calculated the age of the autonomic system method of analysis of heart rate variability.
WMe2 removes cardiogram, ie records the heart's electrical signals. But only one diversion (in a medical institution is removed from the lead 3-12) and only in order to evaluate the difference in the duration of heart rate.
And the results that appear when decoding, called cardiointervalogram.
Cardiointervalography - method of research activity of the heart based on the graphic recording intervals between successive R-wave of the electrocardiogram.
High battlements in cardiogram indicated by the letter R, and are key, as is signaled to initiate in the ventricles. The intervals between these teeth are not exactly the same, and they determine the rhythm.
Signal variability rhythm WMe2 assesses spectral analysis. Thus cardiosignal portions are divided into individual components according to their amplitude-frequency characteristics.
This is what we see in the decoding results from WMe2, where the abbreviations represent different components of the range. Without going into details, we get this:
- HF-component (High Frequency) shows the influence of the parasympathetic division.
- LF-component (Low Frequency) shows the effect on the heart rate of the sympathetic division.
- VLF-component (Very Low Frequency) demonstrates the effect of the factors supporting the consistency of the medium in the body.
- Depending on how often different wavelengths in the measurement, it is possible to determine what portion of the autonomic nervous system is now affecting your condition. This is reflected in the index balance LF / HF.
How can we help all the medical data?
Very simple. SNC provides all reactions and processes in the body. The bends and disruptions in the balance of the ANS lead to arrhythmias and occurrence of mass diseases of vascular dystonia and allergies to gastric ulcers.
Simple indicators in the form of balance and age VNS help evaluate how your physical and correctly matched emotional stress, whether you have stress, whether it is necessary to run to the doctor or simply like to be right now relax.
Once you see that "growing up" - it's time to relax. And if WMe2 consistently shows that the older you are, what is written in the passport, it is time to change the mode.
By the way, the results can be sent to clinics. Russian on the list yet, measurements have to inform your doctor without the aid application.
For training
During training WMe2 controls constant pulse, it needs to be worn on special clothes sensor, to which the tracker is attached with the dongle. Developers have released a men's shirt, ladies top and kardiopoyas.
Sports top looks stylish, but important remark: take one size larger! Least. Of course, when socks fabric stretch, but in my top was hard to breathe, so serious about checking it was not only yoga.
You choose the type of activity, which are going to do, and specify your heart rate at rest (or are measured at the present moment). All the time you do, the sensor monitors the heart rate and shows the zone in which you are. On the charts easier to keep track of whether you pick up the load correctly.
breathing training
WMe2 not only monitors the state of the autonomic system, he is also helps to normalize the balance, if you have a problem with that. To do this, perform breathing exercises for the application program. Keep sensor as in the measurement of the state of the ANS, and follow instructions. Proper training should adjust the balance between the divisions of the nervous system.
Bracelet believes that the stress I do not know how to cope, but to the middle of a workout I fell asleep. So it helps to relax.
trends
The app collects statistics and allows you to track the progress of both the individual indicators, and on all measured parameters as a whole, showing clearly how your condition depends on the mode.
Minuses
Minus one. This is an unstable operation of Android-application. Several times the testimony just have not been removed, and I had to admire here on these posts.
In this case, successful measurements do not deviate from the data obtained for comparison in the clinic: the heart rate of the ECG results, blood pressure and pulse WMe2 displays with minimal error.
On iOS, the app is running smoothly.
Output
They still exist! Non-invasive sensors health monitoring, which can carry anytime, anywhere, and that show accurate results.
The device includes a program for the gym, but its main feature is not a standard measure heart rate (pulse, it seems, will soon be even measure irons), and heart rate analysis and the conclusions that we can do on the basis of data.
I can not recommend WMe2 as an exclusively medical device with any diseases, but for WMe2 prevention tool will bring many benefits.
Layfhaker is grateful to online store Medgadgets.ru for providing the test device.
