Claim Text:
1. A sensor comprising: a stand; a first body connected to the stand to be movable along a sensing axis by first suspension means defining a suspension plane; two resonators that are arranged symmetrically about the first body along the sensing axis and each of which comprises a pair of second bodies each connected to the stand by second suspension means in order to be capable of vibrating along a vibration axis that is substantially perpendicular to the sensing axis, and that are connected to each other by third suspension means; transducer members connected to a control unit for detecting a position of the first body relative to the stand, for setting the second bodies into vibration along the vibration axis, and for detecting respective vibration frequencies of the second bodies; and surface electrostatic coupling means connecting each second body to the first body in such a manner that a movement of the first body relative to the stand along the sensing axis leads to an increase in electrostatic coupling for one of the pairs of second bodies and to a decrease in electrostatic coupling for the other pair of second bodies.
