Abstract:
1. Electromechanical filter, comprising: a substrate; at least one microtip formed on the substrate and an apex of the microtip extending by a nanostructure in a form of a beam that extends along an axis of the microtip, the microtip and the nanostructure being, at least superficially, electrically conductive, the nanostructure forming a resonator; an electrically insulating layer formed on the substrate and including a cavity in which the microtip is located and, substantially at a level of the apex of the microtip, a bore that extends the cavity, an edge of the bore surrounding the apex; and at least one input electrode and at least one output electrode formed on the insulating layer and that end substantially at the edge of the bore, on both sides of the microtip, the input electrode configured to receive an electrical signal to be filtered and the output electrode configured to supply a filtered electrical signal, a coupling being created between the input and output electrodes and the nanostructure, the coupling enabling the resonator to be set in resonance.
