Whether or not smartwatches are already on the way out the door is still up for debate. One thing that most people can agree on is that battery life remains an issue on almost every wearable currently on the market.

That won’t be an issue with the Matrix PowerWatch, however, as this particular wearable is powered entirely by your body heat using advanced thermoelectric technology.

As with other wearables, the PowerWatch is capable of syncing to an Android or iOS device where it can track your steps, monitor calories burned and keep tabs on the quality of your sleep. A single button press offers up the option to set a timer or access a stopwatch. It’s also capable of showing you how much electricity your body heat is generating in real-time.

At the heart of the Matrix PowerWatch is the AMBI Q which the company tells Engadget is the world’s lowest power-consuming microprocessor. It’s far from a full-featured smartwatch like you’d find from Samsung or Apple but again, it doesn’t ever require that you take it off to charge it.

Matrix Industries is seeking funding for the PowerWatch on Indiegogo. With two months remaining in its campaign, Matrix Industries has generated over $66,000 toward its $100,000 flexible funding goal. A pledge of $99 (free shipping in the US) gets you on the list to take delivery of a PowerWatch in July of next year.
