A wearable inductive-force sensor, which provides high-sensitivity dynamic measurements of both normal force and shear force, utilizes three spiral planar force sensing coils. These spiral planar coils allow the measurement of shear force in the x and y directions and the measurement of a normal force in the z direction. The force sensor is configured to be mounted in various locations, such as an insole of a shoe, so as to provide real-time force sensing of forces that are applied to a patient's feet as they move. In addition, force-measurement electronics used with the force sensor are configured to use resonance-frequency division signal multiplexing to monitor the response of the force sensing coils, which allows the sensor to have minimal complexity, while still being highly sensitive.
