    摘要: An array of micromechanical oscillators have different resonant frequencies based on their geometries. In one embodiment, a micromechanical oscillator has a resonant frequency defined by an effective spring constant that is modified by application of heat. In one embodiment, the oscillator is disc of material supported by a pillar of much smaller diameter than the disc. The periphery of the disc is heated to modify the resonant frequency (or equivalently the spring constant or stiffness) of the disc. Continuous control of the output phase and frequency may be achieved when the oscillator becomes synchronized with an imposed sinusoidal force of close frequency. The oscillator frequency can be detuned to produce an easily controlled phase differential between the injected signal and the oscillator feedback. A phased array radar may be produced using independent phase controllable oscillators.

    摘要: A composite, analyte sensor includes a substrate; a micro- or nano-electro-mechanical (MEMS; NEMS) resonator that is coupled to the substrate at least two edge locations (i.e., it is at least doubly-clamped) of the resonator, wherein the resonator is in a statically-buckled state near a buckling transition point of the resonator; and a chemically-responsive substance covering at least a portion of the surface of the resonator that will undergo a conformational change upon exposure to a given analyte. The resonator may be a double-clamped, statically-buckled beam (or bridge), a multiply-clamped, statically-buckled dome (or crater), or other resonator geometry. The sensor may include two or more at least double-clamped, statically-buckled, composite MEMS or NEMS resonators each operating near a buckling transition point of the respective resonator, and each characterized by a different resonant frequency.

    摘要: A micro-electrical mechanical oscillator has a resonant frequency of oscillation that is varied by application of heat. The resonant frequency is varied at a frequency different from the resonant frequency of the oscillator to amplify oscillations. In one embodiment, the oscillator is disc of material supported by a pillar of much smaller diameter than the disc. The periphery of the disc is heated by a laser to provide a time varying shift of the resonant frequency (or equivalently the stiffness) of the disc. Feedback from movement of the disc is used to modulate the intensity of the laser, and thus the stiffness of the disc to provide parametric amplification of sensed vibrations, using heating as a pump. Various other shapes of micro-electrical mechanical oscillators are used in other embodiment, including an array of such oscillators on a substrate, each having different resonant frequencies.
