A medical instrument (300) having a distal portion and a proximal portion, the medical instrument comprising: a sensor (310) printed on a distal portion of the medical instrument and having at least one coil formed of a conductive material; at least one non-conductive material (430) covering the at least one coil of the at least one sensor; a conductive layer (613, 615, 623, 625, 633, 635) circumferentially printed around the proximal portion of the medical instrument; a non-conductive layer (640) printed on top of the conductive layer; and at least one pair of contacts (320, 330; 550, 560) electrically connected to the at least one coil and coupled to the conductive layer, the conductive layer connectable to a measurement device (160) configured to detect an induced electrical signal based on a magnetic flux change of the electromagnetic field, wherein a location of the medical instrument in a coordinate system of the electromagnetic field is identified based on the electrical signal induced in the sensor. |
