I think of this in the same way as
the generation of electricity through movement by
humans, such as with piezo sensors in sneakers.
Maybe such a jewelry could produce micro-power
just by moving about. Curious about all of this.
Any thoughts are greatly appreciated. brian

I have a watch made by Seiko that operates on that principle. It's from
their "kinetic" series, and I never have to wind it or change batteries.
Great for absent minded types like myself. I can go for weeks without
wearing it, and it still keeps the time.
