I think the chip might come from one of Ben Counter's Grey Knight books. I'm sure it is mentioned when he talks about the crew of Alaric's Strike Cruiser; the crew are described as having had their emotions 'pruned' so that they stay focussed and unafraid, and also that they have explosive devices (either implanted in their brain, or in a collar around their neck) that monitors them for extreme mental distress. Should the device record a certain set of stimuli, those that are typical (if the word 'typical' could ever be used for such an event!) of daemonic possession/attack, then it kills the person rather than let them fall to the daemon.
It might even be that it's not the crew of the Strike Cruiser but, instead, it's the Servitors on Titan who aid in the interrogations of those who have fallen to daemonic taint, or who work in the libraries full of forbidden knowledge. Either way, I'm sure this 'chip idea' comes from Ben Counter.
I can see it being useful in some circumstances, but a real hindrance in more. You'd also have to keep such a thing for use on low-level functionaries, using it to police those who don't have the mental capacity to protect themselves, but who are too numerous/engaged in repetetive and boring tasks that having an overseer who could protect them would be a total waste of resources; after all, these folk are eminently replaceable!
