​        Recently conducted studies show that a small adhesive sensor can find out quite a bit about your body based on your perspiration. The sensor can even send the information gathered from your sweat wirelessly to your smartphone. This sensor could potentially become the easiest way access someone’s health information in the near future, maybe even replacing blood tests. Sweat is obviously much easier to get than blood, which makes it very possible that these sensors could soon be used as an alternative to blood tests.  Sweat can be used for a number of things including diagnosing diseases and uncovering drug use. Perspiration can be used for these things because it is a chemical full of molecules ranging from electrically charged ions to more complex proteins that can help show what is happening inside of a human body.

          In more recent studies, chemical sensors were implanted in a small, soft, silicone rubber disk that can stick to skin to collect and analyze sweat to show health markers. For example, the sensor can tell you how you are responding to workouts and exercise. It can even tell you if you need to drink more water or replenish your electrolytes as well as show you your sweat rate and loss. This device will allow people to monitor their health with more ease and efficiency than ever before as it will show you the information right on the spot. This sweat sensor is just another example of how advanced technology is getting in recent years and how the future of tracking and maintaining good health is looking bright.
