Abstract:
1. An electromechanical filter comprising: a first member for inputting a signal; a second member disposed at a predetermined distance from the first member so as to surround the first member and to be excited due to an electrostatic force caused by the signal input from the first member; and a third member disposed at a predetermined distance from the second member so as to surround the second member and to detect vibration of the second member, wherein the second member receives an attractive force from the first member and the third member so as to be bound and regulated to generate vibration in a rotation direction, wherein the first to third members are conductors, and each of the second and third members has portions differing in permittivity circumferentially, and wherein signal transfer is performed in accordance with a change in electrostatic capacity between the second and third members.
