Wearables and Sweat Tracking

Technology has always been intimately linked to the human body. From sharpened flint to smartphones, we've been carrying our inventions for millennia—but the relationship is about to get even closer. The next generation of electronic devices might not just be near our bodies, they could be powered by them.

Staying alive guzzles energy. To keep us ticking, our bodies need to burn between 2,000 and 2,500 calories per day, which is convenient enough to power a modestly used smartphone. So if just a fraction of that energy could be siphoned, our bodies could in theory be used to run any number of electronic devices, from medical implants to electronic contact lenses—all without a battery in sight.

Sweat-powered wearable

Wearable devices for health monitoring and fitness management have foreseen a rapidly expanding market, especially those for non-invasive and continuous measurements with a real-time display that provide practical convenience and eliminate safety/infection risks. 

Forget about other devices, currently, our sweat can charge up the wearable electronics that we carry with us, i.e., smartwatches. The smartwatches that are assigned the task of keeping our daily health record and tracking our calories and sweat burn out, will now be automatically charged by our sweat.

Advantages of Sweat tracking Smartwatches

The battery life of any electronic device that we use is the first-most bothering thing. That one feature which we surely check is the battery power and how long will it's one charge last. Our smartwatches are one such device that we can not afford to keep away from us. We get them only to keep a track of our hourly physical activity. In such cases, especially charging them up is a disadvantage.

But the idea of Sweat power has added new features to the smartwatch and will increase its demand as well.
