Hello.  I have a strange request for information.  I am trying to
develop a penetration grid application using a single layer flex grid.
The penetration grid is basically a simple break-wire system.  The
problem is that all the flex materials, we have tried to use, have been
too rugged.  This penetration grid needs the characteristic of being
almost fragile/brittle so that any attempt to puncture the grid or
seperate the traces from the substrate would cause the traces to
fracture (open circuit).  I understand that making the grid fragile
means that it probably cannot be produced.  But is there some surface
treatment that can be done, after processing, to cause this fragile
effect?  Is there some substrate material that could "age" quickly after
manufacture?  Is there a different conductor metal which could help this
fragile effect?  Any help would be greatly appreciated.

Thanks,
David Plentovich
