An apparatus having a shaft that can sense the depth of penetration, for penetrating into an object (the substrate). The substrate being penetrated has impedance that varies according to the depth under a surface of the substrate. The shaft has a tip for penetration and has conductive ends near to the tip of the shaft. A change of impedance of material of the object between the conductive ends can be sensed to provide information on the depth of penetration. A processor can be provided external to the object being penetrated by the shaft to gather and process the impedance information to determine whether the desired depth has been achieved.
