8. A position sensor, comprising:
(a) a flexible substrate formed into a three-dimensioned object defining an opening extending along a central longitudinal axis;
(b) a first field-sensing coil formed on a first layer of the flexible substrate, the first field sensing coil defining a closed-loop shape that fully encircles a first axis, the first axis being orthogonal to the central longitudinal axis; and
(c) a second field-sensing coil formed on a second layer of the flexible substrate, the second field-sensing coil defining a closed-loop shape that fully encircles a second axis, the second axis being orthogonal to both the central longitudinal axis and the first axis, the first field-sensing coil and the second field-sensing coil being located at a common longitudinal location, the first field-sensing coil and the second field-sensing coil being configured to sense components of a magnetic field oriented along the first axis and the second axis, respectively.
