Abstract
A resonant sensor including a support, a proof body suspended from the support and having a resonant frequency ωa, an element that measures a force including at least one resonator of resonant frequency ω, the force being applied by the proof body, and a mechanical decoupling structure interposed between the proof body and the resonator. The decoupling structure includes a decoupling mass, a first connecting element between the decoupling mass and the proof body, a second connecting element between the decoupling mass and the resonator, the decoupling structure having a main vibration mode whose resonant frequency ωis such that ωa<ω<ω, the decoupling structure forming a mechanical low-pass filter between the proof body and the resonator.
