Apple is apparently working on a new and innovative hydration sensor, which will be used on its wearable products. A new patent has revealed the new technology that is the first of its kind for its Apple Watch.
The patent was first spotted by PatentlyApple on the USPTO and was titled as “Hydration measurement with a watch.” In this patent, the Cupertino based tech giant added that “Traditional techniques for tracking hydration are generally invasive, expensive, or unreliable.” This refers to all the existing methods that determine hydration through methods such as a single test fluid sample. So, in other words, the company is working on a new technology that would not require such a process.
The patent describes a hydration sensor that uses non invasive electrodes that are placed against the skin. Apple describes this method as a “reliable and elegant” solution that would work by measuring the electrical properties of the Apple Watch user’s sweat. The patent adds that “a high level of electrical conductance of the perspiration can indicate a high concentration of electrolytes and a low level of hydration. By further example, a low level of electrical conductance of the perspiration can indicate a low concentration of electrolytes and a high level of hydration.”
Notably, the patent description also describes the sensor’s function in detail. The iPhone maker adds that its hydration tracking system will function “non invasively, repeatedly, accurately, automatically, and with minimal user intervention.” The patent also states that users’ hydration levels are an integral and important aspect of their health. It is especially important to provide this data after the user performs physical activities like working out since it offers a structured water intake management system that also encourages the user.
