    What insulating materials can I use?

    Any that's ~ 0.05mm - 5mm thick -  e.g. electrical insulating tape if you wish.

    How could I cover the metal material(sensor) with the insulated material, the printing , plating or coating? 

    That'sf or you to decide - it's a mechanical decision for you. Electrical tap if you like.

    Do I only cover it on the surface where we touch? or both sides?

    Only where you touch.
