I will put on my engineer hat. If budgets were unlimited, and the scoring equipment could be made lightweight I can think of some interesting possibilities.

You could go beyond a simple electrical connection to determine a "touch" and all of the associated problems (whipping so that the side of the blade contacts for a score). You could utilize pressure plates and set a threshold amount of force for a cut, or a duration of contact to ensure a push/pull motion. This could be adjusted for different weight classes/age groups, or the thresholds could be adjusted if one wanted to simulate armoured vs unarmoured combat. Some issues could arise with respect to ai-men etc, a simple electrical system might be able to signal who hit first, however in an ai men situation, both people are essentially "dead", so a threshold would need to be set to allow for overlaping contact.

You would need some intelligence for nidan waza, if a kote was scored electronically good, but the men was not considered "correct". This would account for the need for live shimpan as well.

This could be good. Or simply adding a vibrating flag, if the hit is landed, then the correct flag will softly vibrating and the rest is depend on the shimpan's judgement. But to add a very light, thin and durable devices are challenging.

That is a neat idea.
