Abstract
A medical instrument includes a printed sensor, a surface, at least one non-conductive material, and at least one pair of contacts. The sensor has at least one coil formed on a conductive material. The surface is suitable for receiving the printed sensor and can be placed in an EM field. The at least one non-conductive material covers the at least one coil of the sensor. The medical instrument contains multiple conductive and nonconductive layers. The at least one pair of contacts are electrically connected to the at least one coil and connectable to the conductive layer, the conductive layer coupled to a measurement device, which senses an induced electrical signal based on a magnetic flux change of the EM field. The location of the medical instrument in a coordinate system of the EM filed is identified based on the induced electrical signal in the sensor.
