I was wondering If anyone's tried to make micro dermal jewelry that can vibrate with piezoelectric ceramics; similar to north sense, but just a buzzer that can be screwed on and wired into an external device. I'm planning on making a few later this year for a project, but if I can find pre-assembled versions of the parts I'm looking for it'd be really helpful. I want to make a haptic device that's easy to install, so someone with no knowledge of grinding can just buy it and immediately use it with little to no instruction.
