“Your screen knows if you are thirsty”: a smartphone detects dehydration with 92 % precision thanks to AI and its capacitive sensors

Technological advances transform our daily life every day, and smartphones are no exception. However, In Saudi Arabia, researchers have highlighted an unsuspected capacity of the screens of our mobile phones. Therefore, These screens, known for their tactile sensitivity, could play a crucial role in dehydration detection, an often underestimated health problem. For example, This fascinating discovery opens the door to new medical and preventive applications at hand.

Dehydration: a major health “your screen knows if you issue

Dehydration is manifested by a water deficit. Therefore, mineral salts in the human body, vital elements for its proper functioning. Similarly, With almost 60 % of our body composed of water, maintaining an optimal hydration level is crucial. Furthermore, Symptoms of dehydration can range from the simple feeling of thirst to more serious disorders. However, such as fatigue, dizziness or even kidney complications. Furthermore, Thus, the possibility of monitoring its hydration using a smartphone could have significant repercussions on public health.

A revolutionary technological innovation – "your screen knows if you

Researchers at the University of Sciences. Technologies of King Abdallah (Kaust) in Saudi Arabia explored the potential of capacitive screens of smartphones beyond their initial function. These screens, designed to convert tactile signals into digital controls, can also measure the skin’s capacity to store electrical loads. This capacity being influenced by the level of hydration. scientists combined this technology with artificial intelligence to create a personal hydration measurement device.

Results that arouse hope

The results of this study are promising.. By analyzing the data of 4. 000 participants, including many athletes observing Ramadan, the researchers have managed to differentiate the states of hydration and dehydration with a precision of 92 % among athletes and 87 % in other participants. These results demonstrate the potential efficiency of this technology for daily hydration surveillance. According to Soumia Siyoucef. a former student of the research group, this method could allow a simple and fast evaluation of hydration by simply placing a “your screen knows if you finger on the smartphone screen.

To an extended application

Although this technology is particularly interesting for athletes. people during fasting periods, it could also benefit other vulnerable “your screen knows if you groups. The elderly. often subject to dehydration due to the decrease in the feeling of thirst, could greatly benefit from this device. Likewise, children, who do not always think of drinking enough, could be better protected thanks to proactive surveillance. This innovation raises the hope of reducing the risks linked to dehydration in a simple and accessible way for all.

The capacity of smartphones to detect the level of hydration may well revolutionize our approach to health prevention. If this technology finds its place in our daily lives, it could transform our way of managing our well-being. However. this innovation also raises questions: how to integrate this technology in a secure and efficient manner in the devices we use every day?
