    Abstract: A method and system for measuring displacement of a structure is disclosed. The method and system comprise providing a first capacitance and providing a second capacitance. The first and second capacitances share a common terminal. The method and system further include determining a difference of the inverses of the value of the first and second capacitances when the structure is displaced. The first capacitance varies in inverse relation to the displacement of the structure.
