If people discuss renewable power, sweat isn’t exactly something that springs to mind. Still, it seems like that organic bodily process is effective at digesting fitness trackers and maybe even smartwatches too.
Researchers at the University of Glasgow in Scotland have generated tech that may use sweat to substitute traditional batteries in devices. It operates by collecting the sweat you naturally produce and causing the ions in it to respond to polymers from the technician, leading to a reaction that creates electricity.
The investigators analyzed the technician by strapping a small version of the mobile to runners and using them exercise – the mobile-powered a load of LEDs, showing that it works, and might theoretically operate to a larger scale also.
How can this smartwatch work in real life?
Depending on the results of the experimentation, the sweat-powered technology works. However, it does not seem like it generates enough power to permit you to forgo conventionally charging your wearable apparatus entirely.Instead, the sweat tech could supplement regular charging, which means that you’d need to charge your fitness tracker or smartwatch far less often than you have to.
The technology appears ideal for fitness trackers, as generally, you wear them if you’re busy. But it’s possible the tech would work in smartwatches too. It isn’t clear when or if we’ll find this tech pop up in real wearables.
Still, it likely won’t be for a couple of years. We often hear of scientists generating tech that could revolutionize your merchandise. Such as super-thin smartphone camera lenses or super-long-lasting graphene batteries. Still, they don’t necessarily make their way into products that you can purchase.
Sweat Powered Smartwatches
Saying this, sweat-powered smartwatches and exercise trackers could be hugely valuable. Both for daily use to help save you charging your device regularly. And for the ecological ramifications of reducing our power usage and battery consumption. Hopefully, we will see the tech soon, then.
