I don’t think this design will amount to anything. The modern cuff design has stuck in part because it’s very simple to use, and also very durable. When you start adding more moving parts and gadgets, you have more points of failure, and more things can go wrong when you are trying to get these things on an uncooperative person.

If your intention is a standard arrest, conventional cuffs are just the ticket.
On the other hand, if you have neutralized a cell of folks that need to be made an example of, parading them around prior to an eventual execution might be beneficial to creating a controllable environment. Nothing like watching your hero contort with Tased energy.
And the 'enemy' (a.k.a. us) can't stage a rescue, because with a push of a button, you can inject your prize with a lethal dose of whatever you like.
