In my sci fi world there is a small device that, when injected into someoneâs blood, cancels out special abilities/superpowers. Itâs used in prisons by the government the protagonists are rebelling against. I was thinking about making it also be used to cause physical pain in to punish prisoners who step out of line, possibly controlled by remote, but Iâm not sure how that would work. What would a chip in someoneâs bloodstream need to do to cause pain? Would that even be possible?
I can think of several ways it would be possible. My instinct was that it would have a high mortality rate but then I realised that I actually have no way of knowing because this is pretty far from modern torture.
 I can see the appeal in this sort of fictional idea. However that comes with the proviso that torture is generally very very low tech. We live in a world where you can literally 3D print an oesophagus and the most common form of torture globally is hitting people.
 There is a really strong tendency in fiction to show these incredibly complicated, high tech torture devices: often implying that torture is complicated, âskilledâ and can be âimprovedâ with technology. None of these things are true.
 Personally I feel like these tropes feed in to torture apologia. Theyâre not the worst form of it out there, but theyâre false and they function in a way that supports what torturers say over what survivors say.
 I think that you can probably write this kind of remote control press-button-for-pain scenario without tripping in to that. But only if youâre aware itâs a possible problem in the first place.
 As for how it could work- My first thought as a chemist was âby releasing something into the bloodâ but I donât think that would work as youâve described. I think it would require a much larger implant then youâre implying in order to release a sufficient quantity of anything.
 Which is possible, arm implants along these lines exist. Theyâre bulky enough to feel through the skin and they need to be replaced periodically to keep functioning. Iâve never had one and Iâm not a medic so I donât know any more then that.
 If youâre willing to research medical implants and adjust the idea a little⌠Well we often use capsaicin as a way to test an animal still has the capacity to feel pain*.
 The LD50 in mice (lethal dose for 50% of the tested population) is 47.2mg/kg. It is possible to be poisoned by capsaicin although I do not have much information on what that looks like in humans. Thereâd be risk of poisoning from repeated abuse by the guards in this story. Thereâd also be a risk of poisoning if the device itself malfunctioned or was damaged and say⌠burst.
 Something smaller (I think the word âchipâ implies something quite small) would work differently because it wouldnât have the space to hold a significant amount of any chemical.
 I think that electric shocks are probably the most likely method with a smaller device. Which also comes with a significant risk of killing someone.
 Iâll be honest I have no idea what kind of difference it would make if the electricity was applied underneath someoneâs skin. It isnât something Iâve seen before. I suspect the heat generation might cause problems. It could damage tissues and cause blood clots which would increase the chance of lethal heart attacks or strokes.
 If the heat killed a lot of tissue around the device I think that could lead to⌠serious problems, possibly death. Having a lot of dead, rotting tissue in the body is pretty dangerous.
 Generally repeated electric shocks kill, sometimes from heart failure, sometimes from things like falling injuries.
 Itâs also (unsurprisingly) incredibly painful. Alleg has a pretty good description of his experience of electrical torture in The Question. You can also find descriptions online as the use of Tasers and stun guns has become more common globally.
 Iâm finding it difficult to judge this one because my instinct is that delivering an electric shock internally would cause additional damage. But Iâm not sure what that would look like.
 Again I think this sort of device could easily malfunction and kill someone. Or malfunction and just stop âworkingâ.
 Thereâs also a chance of the immune system attacking the implant. Which- I donât know a lot about because Iâm not a medic. I think it could be an important factor though.
 With both of these ideas itâs worth questioning whether this would be worth the effort. Iâve found a lot of authors donât quite think this through so let me try and break it down.
 This is what has to happen before it can be used:
it needs to be designed
a prototype needs to be created
it needs to be tested
several iterations of redesign and new prototypes
parts need to be sourced
the whole thing needs to be assembled on a larger scale
it all needs to be paid for
the people who are supposed to be using it need to find it easy to use
 Tasers very nearly didnât make it off the ground. It took decades of concerted work and funding from their manufactures to make them a âsuccessâ. Rejali does a pretty interesting run down of the way it happened if you want more information.
 The question you need to ask yourself is: would all of this have any advantage for the abusers compared to using pepper spray, Tasers or a stick?
 Because unless youâre really sure the answer is âyesâ then I think this sort of thing is really really unlikely. And when it comes to writing torture simpler is usually better.
 Like I said I can see how the base of this idea could add to your story. So I donât want to dismiss it out of hand. But the existence of a device like this says a lot about the society youâre writing. Do the implications fit with the world youâre building?
 Torturers are⌠generally incredibly lazy and pretty dumb. Which makes the use of high tech devices less likely. Because the competition is a slap. For something to take off it needs to be as easy, quick and reliable as that. And probably also robust enough to be stamped on, vomited over etc.
 So: is there enough drive in this world to add torture to the functionality of this device? Is there the money to fund it? Is there the time to design and create it? And is it going to be reliable and tough enough to actually be used?
 If there was a rush to make something that blocked super powers adding more things (that might interfere with that main function) to the device probably wouldnât have been a priority.
 Basically if you want this kind of device make it fit with the world youâve built and think about whether itâs actually adding anything that a more typical torture wouldnât.
 Aaaand Iâm going to leave it there cos I think Iâm talking in circles. I hope that helps :)
