This clearly isn't a story but just my doing some product design. I've long thought about cellphones as everything you need for a slave collar. Remove the screen, add some punishment feedbacks and you have everything you need for a dystopian scifi movie. Of course, if I did put it in a story, and I have thought of many small stories to put it in, I would have to skip most of the explaining of the device to focus on the actual story.

In terms of look, I imagine something like this.
