A catheter adapted to measure a contact force includes a proximal segment, a distal segment, a spring segment extending from the proximal segment to the distal segment, and at least one inductive sensor. The at least one inductive sensor includes a first plate of high magnetic permeability material disposed on the proximal segment, a second plate of high magnetic permeability material disposed on the distal segment opposite the first plate, at least one first coil disposed adjacent to the first plate between the first plate and the second plate, and at least one second coil disposed adjacent to the second plate opposite the first coil between the first plate and the second plate. The second coil is electrically connected in series with the first coil. The first coil and the second coil are configured to output a signal indicative of displacement between the first coil and the second coil.
