Abstract:
A capacitive sensor comprising:a retaining member; an intermediate member retained by the retaining member such that the intermediate member can rotate around a first axis; a movable member retained by the intermediate member such that the movable member can rotate around a second axis which is perpendicular to the first axis; a weight provided on the movable member; a movable electrode unit consisting of one or more electrodes which is provided on the movable member; and a board on which a fixed electrode unit consisting of one or more electrodes is provided such that the fixed electrode unit faces the movable electrode unit, wherein at least one of the movable electrode unit and the fixed electrode unit includes a plurality of electrodes, and wherein capacitances between the one or more electrodes of the movable electrode unit and the one or more electrodes of the fixed electrode unit change in accordance with the movement of the movable member.
