The Matrix PowerWatch X uses your body heat for charging

Back in 2016, Matrix announced its battery-free PowerWatch, which used body heat to charge itself. While it was certainly an interesting concept, it didn't quite hit the mainstream, particularly due to its limited capabilities, which included noting your activity level, calories burned, and monitoring your sleep.

Fast-forward to 2018, and Matrix has shown off its new and improved PowerWatch X, which once again uses the principle of thermocouple to charge itself off your body heat, while offering a lot more than its predecessor.

According to Engadget, apart from offering basic fitness tracking capabilities, the PowerWatch X can also receive notifications from a smartphone over Bluetooth. What's even better is that the device's proprietary thermoelectric energy converter can generate enough electric energy from your body heat to power a vibration motor, so that the PowerWatch X can vibrate if you receive a call.

But Matrix isn't just stopping at building the PowerWatch X, it's also using thermocouple to develop a "Energy Harvesting Sensor Beacon", however, details of the project are currently unknown.

If you're interested in the PowerWatch X - which has a shipping date of January 2018 - you can pre-order it for $249 from Matrix' website.
