Abstract
A variable capacitance device including at least one first fixed electrode and a second electrode free to move with respect to the fixed electrode, each electrode including a body and protuberances projecting from at least one face of the body. Each electrode is arranged such that the faces of each electrode provided with the protuberances are facing each other, the distance separating the two faces facing each other being greater than the sum of the heights of a protuberance from the fixed electrode and a protuberance from the mobile electrode. The electrodes are capable of moving with respect to each other in two parallel planes along at least one main direction.
