This Wrist-Worn Device Tells You When You are Dehydrated


Water, water everywhere and not a drop to drink, someone once said. Sure, we have no idea who that someone was, but they sure were right. Human beings need water to survive, even more than food(much to the chagrin of the fast food industry.) Even worse? Many of us don’t drink enough water on a day-to-day basis and have no idea. We go through our lives thinking that coffee, soda and beer count which, of course doofus, they don’t. You need the real stuff. Pure, unadulterated two parts hydrogen and one part oxygen. Now there’s a piece of wearable technology that makes sure we are getting enough of said real stuff.

Developed by Sandia National Laboratories in the United States, this hydration monitor sure looks like a smartwatch doesn’t it? It doesn’t tell the time, however. It does tell the amount of times you should be forcing water down your gullet, however. An array of micro-needles on the underside of the watch-like device sticks into your skin to measure your interstitial fluid levels, which is the amount of fluids between your cells. When these levels perilously, or even just not-so perilously low, it’ll let you know, thus sending you to your closest literal watering hole.

The company envisions this gadget being of great use to hospitals and the military and other places where people routinely get dehydrated(maybe the desert.) They are even in talks with smartwatch makers to put their tech in actual smartwatches, which will no doubt also be able to tell the time.
