You read that right, all you need is body heat and you are good to go anywhere.
Matrix PowerWatch needs only your body heat in order for it to run, claimed by its creators.
Basic functionalities are found on the device like tracking sleep time, counting calories, and such. When removed, the watch will go to sleep and will store data to its memory.
It also got a power meter that indicates the electricity that your body is generating.
The smartwatch is aircraft-grade aluminum that syncs to your smartphone and water resistant to 50meters. Currently up for backers in Indiegogo and is expected to ship in July for $169 or roughly P8500 Philippine peso.
