I dream about the smart device not needing to be charged in a traditional way. But, as mentioned in the article (https://www.wareable.com/wearable-tech/kinetic-powered-wearables-2034), technology is still not there. The startups are not managing to collect money due to the inability to describe and prove the working power-generating method of an on-wrist gadget. The closest they came is an example of shirts made of smart two-layered materials that create static electricity with friction and power LEDs. In the case of tracking devices, I read it also requires much more energy than it can be generated by kinetics at the moment. But a step forward would be a prolonged life of ordinary devices with kinetic charging add-on.

This is how the old Seiko kinetic powered watch worked https://core.ac.uk/download/pdf/295649.pdf. I can even think of a better way to do this. I'm sure someone has done it but can't seem to find it at the moment. Imagine a looped plastic tube, coil spun around it, then a magnetic ball would freely move around it as the person moves. That would create a small charge which can be fed into a capacitor until it builds up enough to be pushed into a battery. Depending on the battery size anything could be powered. It would just take a lot of time for enough power to build up. But with the GPS tracker, we only need one transmission to find whatever we are tracking.
