Matrix Industries PowerWatch 2 Review

Matrix Industries PowerWatch 2

Smartwatches that track your movements and vital functions are increasingly popular. What’s less popular is having to charge them up each evening. Made by a subsidiary of thermoelectric specialist Matrix Industries, this here PowerWatch gets around that by harvesting your body heat to power a device that’s as feature-rich as its rivals, yet never needs plugging in.

This wizardry is achieved by converting temperature differences directly into electrical energy through a phenomenon called the Seebeck effect. Needing a hot side and a cold side to operate, the hot side is the aluminum plate on the back of the watch, while the cold side is the entire metal bezel and body.

With the two separated by a layer of insulating thermoplastic, the watch is more efficient in cold climates where the variance between the heat of your body and the ambient temperature is greater. With bars on the watch indicating how much power is being generated at anytime, it’s tech that’s already been proven by the brand’s previous model.

Now, this latest version adds GPS functionality to bring it into line with the very smartest of its competitors. With gesture control and twin audio-haptic feedback, the PowerWatch 2 also includes an optical heart rate monitor sleep tracker, and step-counter.

Pairable with Android and iOS devices, it’s also able to twin with apps like Strava, Google Fit, and Apple HealthKit. At 70 g and just 16 mm thick, it also looks like a conventional watch thanks to an aircraft- grade aluminum casing and sapphire glass face.
