You could probably use an infrared camera and a heat gun. Heat the wall
and then look at it with the camera. The drywall that is against studs
will change temperature more slowly; heat up slower, cool down slower
thus allowing you to see where the studs are.

Wait I have a better idea. First, take down all the drywall. Then
apply uranium radition to the studs. Then put up new drywall. Then
get a geiger counter and voila - you'll hear a bunch of loud static
when you get near a stud. Brilliant!
