Non taken. Its a good show stopper though lol.

When the plate inside the stud finder is over wall board, it will sense one dielectric constant (sort of like an insulating value); but when it is over a stud, the dielectric constant is different. It works on a capacitance differential generated by density difference. The circuit in the stud finder can sense the change and reports it on its display. The second patent below shows you exactly how to build this sort of stud finder.

The latest technology in stud finders uses a very small radar system to detect the stud.

I turned out my walls are not built with wooded studs as I thought but rather metal ones..The stud detector actually picked them up easily in the end...
