Does grounding occur if I stand, walk barefooted, or wear grounding shoes on a ceramic tile, wood, or carpet flooring?

If tile is unglazed, and sits directly on a slab or ground, yes, you are grounded. If the tile sits on plywood or some other kind of wood, plastic, or vinyl under structure, you will not get any conductivity. Grounding does not work if standing on carpet or wood floors (which insulate and prevent contact with the earth's electrons).
