20090289314 | MICRO-ELECTROMECHANICAL RESONANCE DEVICE WITH PERIODIC STRUCTURE - A Micro Electro Mechanical Systems resonance device includes a substrate, and an input electrode, connected to an alternating current source having an input frequency. The device also includes an output electrode, and at least one anchoring structure, connected to the substrate. The device further includes a vibratile structure connected to an anchoring structure by at least one junction, having a natural acoustic resonant frequency. The vibration under the effect of the input electrode, when it is powered, generates, on the output electrode, an alternating current wherein the output frequency is equal to the natural frequency. The vibratile structure and/or the anchoring structure includes a periodic structure. The periodic structure includes at least first and second zones different from each other, and corresponding respectively to first and second acoustic propagation properties. | 11-26-2009 |
