Strong mechanical vibration have well known negative consequences, like
nerve damage and problems with blood vessels. The circulation is
hampered. But these effects appear at strong vibrations, like when using
a pneumatic sander.

I don't think the device we are talking about would need so strong
vibrations that there is any need to worry about such effects.

We touch and feel things all the time and that does not damage the nerves
or circulation.
