ABSTRACT:
A nano-electromechanical filter. The filter includes, on a substrate, at least one microtip extended by a beam-shaped nanostructure. The microtip and the nanostructure are at least superficially conductive. The nanostructure forms a resonator. At least one input electrode and at least one output electrode are formed on an insulating layer, on both sides of the axis of the microtip, in the vicinity of the apex of the microtip. The input electrode receives a signal to be filtered and the output electrode provides a filtered signal. The filter can be particularly applied to wireless communications.
