Monitoring is in fashion, carrying devices “Wearables” What they are called is something that we see more and more common, to be loaded with sensors by the body and that these are part of our daily clothing is the price that we have to pay if we want to have a better control of our day to day.

Jawbone is just one of the many companies that are dedicated to the manufacture and sale of these devices, among them we recognize brands such as Fitbit, Garmin, Xiaomi, Nike, Misfit and even Razer itself with its Nabu, but Jawbone with its UP3 has been successful in something about the others, I mean the approach.

The Jawbone UP3 is a smart bracelet, but it is not a fitness tracker, it does not notify you if they call you, nor does it vibrate if they send you a message, nor does it have a screen that shows you information, does not do any of that.

The Jawbone UP3 is a Healt Tracker, and it is precisely that (and that is the most advanced in the market even today) that makes it special and allows it to stand out from the rest.

Instead of being a device oriented to people who are already active, this focuses on sedentary people, a bracelet that helps to understand our health and how our day-to-day affects our body and mind.

Mission: Improve our health

Counting steps, calories, distances traveled, the phases of sleep and all those things is nothing special, charging almost € 200 for a bracelet that only does that is a sin, for this we have the beautiful Xiaomi Mi Band 1S that for € 20 It even includes an optical heart rate sensor, but then, what does this bracelet do that allows it to reach that value?

The Jawbone UP3, unlike the rest of wearables, is an invisible bracelet, a device with the latest technology capable of hiding in our sleeve with subtlety as if it were a more aesthetic accessory, a bracelet that presents quality finishes that can even pass as a mere aesthetic accessory, but after that fine and precious class layer and exquisiteness hides a whole engineering feat, loaded with sensors such as a three-axis accelerometer, a Bluetooth 4.0 LE module and a set of "bioimpedance" sensors.

Bioimpedance sensors?

It is normal that you have doubts about the functionality or purpose of these sensors, and it is precisely here that stands out above the others, these sensors are located inside the circle of the bracelet, arranged in the form of 5 metallic squares with golden appearance (whose existence one ignores when wearing it thanks to its fine profile and rounded tips) divided into two groups of two and one loose at the top.

Using these sensors, many things are measured, such as the electrical resistance of our skin, the beats per minute of our heart, our breathing rate and even what is known as "Galvanic Cutaneous Response" or (GSR), the latter is, to understand it simply, what we notice when we get a scare, that chill or tension that runs through our body, both when we are sad, and when we get scared, as when we are happy, we I could say that it is like an emotional response through the skin.

What are these sensors for?

Well, thanks to them, the Jawbone UP3 can measure things like the beats per minute of our heart every few minutes during The 24 hours of the day (without spending hardly any energy on it), our breathing and body temperature.

These data allow the bracelet not only to follow our heart rate throughout the day and all night (to detect the impact of our lifestyle on our heart), but to know when we are in the REM sleep phase, a unique feature that only UP3 is capable of, and this is more important than it seems, since conventional wristbands measure the sleep phases by following 3 of them (Awake, Light Dream and Deep Dream), but the REM phase it is a phase as important as any other, it is the phase in which we are dreaming, during this phase (REM = MOR = Rapid Eye Movement) our brain repairs its cells and establishes the neural connections necessary to consolidate short-term memory into memory in the long term, while the phase of deep sleep what it does is repair the muscles and joints such as tendons.

Knowing how many hours of REM phase we have enjoyed in one night allows us to have a better idea about whether we have rested well or if our brain still needs a rest, since quantifying and analyzing sleep is more difficult than saying Light Dream and Deep Dream, something that only helps us determine when we are more likely to wake up.
