I don't know about damaging the machine but wet wood has a similar capacitance to our fingers and that is why it stops the blade like that. I wonder if the system can evolve the way airbags did for cars? In the beginning airbags would go off with little provocation; now they are smart enough to realize that they should not go off at all even in a mild crash.

Here's a good video of the mechanism: http://www.youtube.com/watch?v=E3mzhvMgrLE http://www.youtube.com/watch?v=E3mzhvMgrLE I'm not sure there's much wiggle room in terms of "finger detection" (as others have said, conductivity of wet wood is just very similar), but perhaps the brake could be designed in a way that doesn't trash the machine every time it goes off.
