consuming eight hours of sleep, eating three times a day, and drinking water. To keep at least somewhat steady, these are typically the three things that doctors advise the most, aren’t they? However, one or more of those three are forgotten by some of us. consuming water. Every day, two litters. Each and every day! to prevent dehydration, particularly as the northern hemisphere approaches summer and temperatures rise sharply.
Well, there aren’t always obvious symptoms of dehydration. You might hardly feel thirsty if you’re dehydrated. Did you know that you’ve already started to lose vital physiological processes when you start to feel thirsty? Even worse if you engage in prolonged exercise or fasting.
By simply touching the screen of a phone with your finger, a group of scientists has created a sensor that can determine your level of hydration! Similar to how it recognizes your fingerprint to unlock your phone, you can now determine if you need to drink water because you’re becoming dehydrated.
How does this app work?
A device created by King Abdullah University of Science and Technology (KAUST) can determine your level of hydration simply by touching the screen of your phone.
You don’t need anything else because your phone already has a capacitive sensor system that can identify changes in skin conductivity linked to dehydration due of a certain algorithm and the sensitivity of the screen.
The best part is that no special phone is required; it can be used with any standard touchscreen!
How is hydration measured from your phone?
Your finger is placed on the screen, and an electrical reaction is examined, just as with any other fingerprint scanner. Because electrical conductivity is reduced in dehydrated individuals, the system recognizes these changes and notifies the user to drink more water.
This study was conducted by Tareq Al-Naffouri, who evaluated the system on two populations at risk for dehydration: elite athletes following physical activity and Muslims during the month of Ramadan.
What is Ramadan?
One of the most significant months in Islam is Ramadan. One of the five pillars of Islam, sawm (fasting), is observed by Muslims during this month. It entails abstaining from food and liquids from sunrise to sunset. It honors Muhammad, their prophet, who received the first revelation.
Therefore, it is true that those who observe Ramadan are far more likely to experience dehydration because they fast for extended periods of time.
Applications in health, sports, and more
Beyond personal wellbeing, this technology might be included into healthcare programs for the elderly, people with long-term conditions like diabetes, or even help prevent heatstroke in settings with extremely high temperatures.
How did they do it?
As previously said, both your finger and your phone already have all the features. They carried out this investigation using bioelectronics. Assume for the moment that skin conducts electricity. Your body can hold more electrical charge the more water it contains. However, your body’s capacity to retain that charge is diminished if you’re dehydrated.
This is detected by the FDC2114 board, which is fantastic! Amazingly, it was able to attain 87% accuracy with the fasting group and 92% accuracy with the athletes.
When will it be available?
The developers claim that integrating the technology into current gadgets is feasible and affordable, despite the fact that it is not yet on the market. There is no need to replace the phones’ existing hardware; all that is needed is a software update and algorithm modifications.
As a result, our phones may be used as non-invasive medical instruments. By simply tapping, we may determine whether we need to increase our water intake, much like a test. Don’t you think it’s amazing!
