Use of low conductivity materials will result in a correspondingly small inductive sensor shift, which restricts the measurement resolution of the LDC. For example, water is not an effective target material. Even a saturated salt water solution has a conductivity that is 0.000001% of copper, which results in an extremely small inductive response.

The human body is another poor target; while in some conditions it may appear to provide a noticeable response, the actual source of the shift is a capacitive interaction with the sensor.
