摘要： Disclosed in a non-contacting electric potential sensor capable of being readily reduced in its size, which includes a detecting electrode, an electrically-conductive movable shutter, and a driving unit for driving the electrically-conductive movable shutter. The detecting electrode is to be placed facing a measurement object whose electric potential is to be measured. The electrically-conductive movable shutter is disposed so as to be movably located in a spacing formed between the detecting electrode and the measurement object when the detecting electrode is placed facing the measurement object, so that an exposure degree of the detecting electrode against the measurement object can be controlled. The driving unit includes a current injecting unit for selectively injecting current into the electrically-conductive movable shutter in a direction approximately perpendicular to a moving direction of the electrically-conductive movable shutter.

摘要： An electric potential sensor includes a detecting electrode, a capacitor modulating unit for modulating a coupling capacitance between the detecting electrode and a measurement object by using an electrostatic force, and a shielding unit for electrically shielding the detecting electrode from electric fields due to the electrostatic force of the capacitor modulating unit. An electric potential of the measurement object is measured based on a change caused by the capacitor modulating unit in the amount of electrical charge induced in the detecting electrode. Entrance of lines of electric force due to the electrostatic force of the capacity modulating unit into the detecting electrode is prevented or reduced, so that an unfavorable mixture of driving noise into an output signal of the detecting electrode can be prevented or reduced.

摘要： An electric potential measuring apparatus including a substrate disposed facing a measurement object, a detecting electrode provided insulated from the substrate, and a capacity modulating unit for modulating a coupling capacity between the detecting electrode and the measurement object. In the electric potential measuring apparatus, a region with a dielectric constant less than a dielectric constant of the substrate is formed in the substrate to achieve an increase in resistivity of a portion of the substrate between detecting electrodes, or a decrease in a stray capacity between the detecting electrode and the substrate.
