A conductive lead that connects a medical sensor or probe to a monitoring or analytical machine. The conductive lead is flexible, lightweight and can be manufactured at a very low cost. The conductive lead has a dielectric flexible substrate. Conductive ink is printed upon the flexible substrate. The conductive ink forms contact pads and connection lines on the flexible substrate. The connection lines electrically interconnect the various conductive pads. An insulation layer covers the connection lines The insulation layer can be dialectic ink that is printed atop the conductive ink. Peel-away protective covers are used to cover the contact pads. Any one of the contact pads can be exposed for use by removing the protective cover that covers it. The contact pads are used to electrically interconnect with both the sensor and the machine.
