Smartwatch that need no charging

Smartwatches are becoming ever more ubiquitous (total smartwatch shipments exceeded 6.1 million in Q3 2016, an annual increase of 60 percent) but there’s one major obstacle preventing them from being fully adopted by a dubious public… battery life.

However, that could be a problem confined to history if claims by the makers of the Matrix Powerwatch ring true. Just landed on Indiegogo, the Powerwatch is powered by thermoelectric technology, which converts heat to electric power. It’s the same tech that NASA used to power the Voyager spacecraft and Curiosity the Mars rover.

On the Powerwatch, it takes the body heat of the user and turns that into the juice to run the show.


It’s not a full-on smartwatch, running Android Wear or the like, but it does measure calories, steps and sleep – with the calorie count apparently more accurate than fitness tracker rivals as it analyses this directly from the same heat that it uses to power itself. When you’re not wearing the watch, it has memory on board to store your stats in a low-power state.

I’ve been told by the team behind the Powerwatch that it’s just the first product of the gate of a body-heat powered stable. “We aim to make this energy harvesting technology a reality for the IoT and wearables industries, alleviating the battery recharge/replacement pain point and helping to drive down costs for commercial businesses,” said senior engineer Anne Ruminski


“Also on our roadmap are medical devices, battery-less hearing aids, and smart logistics – energy harvesting sensors that track pallets and shipping containers that are wireless and don’t need batteries,” she added.

Back to the Powerwatch and it offers multiple watch faces, all displaying the power meter of how much battery life your body is generating. It’s made from a rugged aircraft-grade aluminium and is water resistant to 50m. There’s a smartphone app (iOS and Android) that all the info collected by the Powerwatch pairs to and it also syncs up with Google Fit or Apple Healthkit as well.

You can order one now from $99 – the suggested retail price is going to be (55000 naria) $169.99. Shipping is expected to begin in July 2017.
