The Matrix Powerwatch, a smartwatch powered by calories burned, is a new product that finally transcends the inconveniences of other smartwatches. These have an extremely short battery life, as a result of which the market loses a large share of otherwise potential buyers. The Matrix Powerwatch is a watch that never needs charging – it uses human heat to generate energy. In addition to the fact that its hypothetical battery never runs out, it also has a built-in special biometer that allows the user to see the number of calories burned at the expense of charging the battery.
