a head, wherein the head does not have any conducting material;
a neck, wherein an outer surface of the neck has a first conductive layer thereon, the neck has a depression;
a tail, wherein a tip of the tail has a second conductive layer thereon; and
a body extends between the neck and the tail, wherein one or more conductive paths are formed on an outer surface of the body extending between the first conductive layer of the neck and the second conductive layer of the tip, wherein one or more conducting paths are integral with the body, wherein a diameter of the head is more than that of the neck and the body.
