Abstract
Methods of measuring a thickness of a material are disclosed. An oscillating signal at a measurement frequency is applied to a circuit including an inductive component and a capacitive component provided using a pair of capacitive sensor electrodes adjacent the material. The measurement frequency is less than a resonant frequency of the circuit, and the resonant frequency is based on the inductive component and the capacitive component. Information regarding a value of a measured parameter is generated based on applying the oscillating signal at the measurement frequency to the circuit. A value of the measured parameter is related to the thickness of the material.
