I wonder if this could be used to log a person's activities? If it was in their clothing and if movements of peoples' limbs -- brushing against the fabric -- generated data that could be used to determine what they're doing. E.g. 80% chance they're currently sitting typing at the computer. Or at another moment, that they're probably washing some dishes. Or what particular task a factory worker is working on.
