Abstract: A probe for atomic force microscopy (SM) comprising a micromechanical resonator (RMM) and a tip for atomic force microscopy (P1) projecting from said resonator, the probe being characterized in that: it also includes means (EL1) for selectively exciting a volume mode of oscillation of said resonator (RMM); and in that said tip for atomic force microscopy (P1, P1?) projects from said resonator substantially in correspondence with an antinode point (PV1) of said volume mode of oscillation. An atomic force microscope including such a probe (SM?). A method of atomic force microscopy including the use of such a probe.

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.

Abstract: This filter comprises, on a substrate (2), at least one microtip (4) extended by a beam-shaped nanostructure (6). The microtip and the nanostructure are at least superficially conductive. The nanostructure forms an electromechanical resonator. At least one input electrode (16) and at least one output electrode (18) are formed on an insulating layer, on both sides of the axis of the microtip, in the vicinity of the apex thereof. The input electrode receives a signal to be filtered and the output electrode provides a filtered signal. The invention is particularly applied to wireless communications.
