    摘要: A microelectromechanical (MEMS) resonator is disclosed that comprises a substrate and a resonator body suspended above the substrate by means of clamped-clamped beams, where each beam comprises two support legs with a common connection to the resonator body, and the resonator body is configured to resonate at an operating frequency. The MEMS resonator further comprises an excitation component configured to excite the resonator body to resonate at the operating frequency, where each beam is further configured to oscillate in a flexural mode at a flexural wavelength as a result of resonating at the operating frequency, and each leg is acoustically long with respect to the flexural wavelength.

    摘要: A micromechanical resonator device and a method for measuring a temperature are disclosed. In one aspect, the device has a resonator body, an excitation module, a control module, and a frequency detection module. The resonator body is adapted to resonate separately in at least a first and a second predetermined resonance state, selected by applying a different bias, the states being of the same eigenmode but having a different resonance frequency, each resonance frequency having a different temperature dependence. The micromechanical resonator device may have a passive temperature compensated resonance frequency.
