If you’d ever wished for a smart wearable that you don’t need to charge, the Matrix PowerWatch 2 is going to offer just that and it is real, because this fitness tracker uses solar-cell and your body heat to stay charged, which the latter charging method is achieved with a thermoelectric generator.
The PowerWatch 2 has a rather complete set of fitness tracking features, there’s a built-in GPS, a heart rate sensor, and tracks a variety of things such as steps, pace, distance, cadence and sleep.
One might wonder what happens if the PowerWatch 2 hasn’t been worn for sometime, one of the engineers told me that it has a power reserve that would last for a year, and if the battery really dies off, they do have an inductive charger that will revive the watch.
