Matrix PowerWatch 2: This Smartwatch Might Never Need Charging
id="article-body" class="row" section="article-body"> The Matrix PowerWatch 2 mixes solar and thermal power to keep charged constantly.
Sarah Tew/CNET The Matrix PowerWatch 2 is the sequel to a watch I wore a couple of years ago made by Matrix Industries, a thermoelectrics startup in Menlo Park whose headquarters I visited last year. The original PowerWatch worked, but wasn`t great. This version, which I first got a peek at nearly a year ago, feels a lot better. It`s finally close to being an everyday watch I`d use as a casual smartwatch.
It looks like a big old Casio G-Shock on my wrist. But it buzzes. A message pops up. I check it, and my step count, and my heart rate. Basic fitness stuff. I`d say it wasn`t notable, medium.com (pop over to these guys) except the Matrix PowerWatch 2 has been on my wrist for nearly a week and never lost any battery life. And, if all goes according to plan, I`ll never, ever need to charge it.

It`s a smartwatch powered by solar energy and your body heat
It`s still far from the best smartwatch I`ve ever worn, but I don`t think co-founders Douglas Tham and Akram Boukai are aiming for that claim. It`s the way this watch never needs charging that`s the amazing part. The watch`s power recharging can be monitored in the phone app, where daily counts of thermal and solar energy can be graphed (I seemed to generate 170 microwatt-hours one day, while solar power generated another 310 microwatt-hours).
