One of the major problems smartwatch manufacturers have encountered is trying to come up with a way to run the numerous and complex features a smartwatch comes with while trying to give it the best battery life ever. You don’t want to keep charging your watches like it is your smartphone, do you?
Here comes the PowerWatch from Matrix Industries which made it possible, instead of needing to be charged every night, your smartwatch harnessed and converted your own body heat into electricity to keep it running?
The creators of the PowerWatch are using the device as a proof-of-concept for their thermoelectric generator technology, and they’ve managed to make it small and efficient enough to incorporate into a device as compact as a watch.
While other products like this exist, like the BioLite’s Camp. But the PowerWatch needs nothing more than for you to wear it.
How The PowerWatch works:
For this watch to work, it was designed that one side requires a constant source of heat, while the other side needs to remain much cooler. The important factor is the temperature difference between the two, which is why the technology works so well when integrated into a watch.
The human body does its best to remain at a constant internal temperature of 98.6 degrees Fahrenheit. That heat propagates out to the skin, where it can be absorbed by the back of the PowerWatch while it’s being worn. On the other side of the watch is a metal housing and crown, with heatsinks disguised as part of its design, that help it to remain considerably cooler than the side touching the wearer’s skin.
As long as that temperature difference exists, the smartwatch is able to generate all the power it needs to run.
Then, whenever the watch isn’t being worn, it automatically goes into a low-power sleep mode, powered by an internal battery, so that it maintains the correct time and date until you put it back on again.
But the major downside of the watch is that there will be no smartphone notifications popping up on your wrist, which is a major feature for a smartwatch to be missing when even basic fitness trackers let you keep tabs on who’s trying to contact you.
Because the smartwatch is so dependent on the wearer’s body heat for power, it’s also able to accurately track how many calories have been burned during a workout, given their subtle fluctuations in body temperature. This is a major advantage over other fitness tracking wearables that track calories burned by extrapolating data from a heart rate monitor and motion sensors.
