What if there was a smartwatch that would last for months or even years on end without you needing to plug it in or replace the battery? Well, take a gander at the Matrix PowerWatch 2. It is powered by your body heat using thermoelectricity (like its predecessor, which was announced last year), and this time around adds supplementary solar charging technology. As a result, you should never have to worry about battery life ever again (as long as you're alive and you are in reach of sunlight on occasion).
Given its relatively low-power methods for recharging, don't expect power-hogging features like cellular connectivity with the PowerWatch 2. However, it does offer GPS location tracking, heart-rate monitoring, a full-color display, a calorie counter and advanced push notifications from your smartphone. It is compatible with both iOS and Android devices, and it is water resistant to a depth of 200 meters.
The Matrix PowerWatch 2 is currently available for preorder on Indiegogo priced at $199 (the regular price is listed at $499), however most of those 200 early bird offers have been exhausted at this point. Matrix's fundraising goal of $100,000 has already been surpassed thanks to 500+ backers.
If all goes according to plan, the smartwatch will ship in June.
