Why don't we have a similar system as the Seiko Kinetic watches for recharging the batteries from smartbands and smartwatches?
You ever used a dynamo flashlight?
>>107710060What does a dynomo flashlight have todo with smartbands and smartwatches that people wear while doing exercises that require lots of body movement?
>>107709964hi
>>107709964Because you need orders of magnitude more energy for that.
Solar power like the ones from "eco-drive" are much more efficient. Which is why Seiko's "kinetic" line died, while "eco-drive" is still so popular today.
>>107710157>unironically wearing quartz
>>107710228>Wears a watch that is innacurate at Its main job: time keeping
>>107710077Because then you'd know how much purposeful winding you need for 20 minutes usage, before you even try and scale it down while providing 10x as much power.
>>107710157That solar "ring" could work since smartwatches and smartbands have huge bezels. It would even work on most smartphones
>>107710269We have like 98% body/screen ratio on even cheap phones these days.
>>107709964The amount of electricity is way too small
>>107710269No. You don't get enough energy for it.The energy requirements of a simple watch movement and the cheapest smartwatch/band is vastly different.Like a CR2250 can run your watch for 10 years, and the best you get out of a smartband is a couple weeks.
