Transparent electrically conductive coating for capacitive proximity sensor

I am looking for electrically conductive transparent paint or coating , due to adhere on wood metal and concrete ( on glass is also useful) . resistivity may be quite poor . a spray version is best as it must be applied on site (application is Low frequency antenna design for capacitive proximity detection due to transform any object into an electrically conductive sensor )

YOU CAN USE SILVER MIRROR TECHNIQUE , ON GLASS IT IS DULL BUT YOU CAN SEE THROUGH.

Hi

I am looking for electrically conductive transparent paint or coating that can be spray painted unto wood or finish paints like acrylic. The application is for a sensor that detects the change in current when you touch the surface(note the level of current using is less than 1 amp).
