    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. A method for sensing an analyte in ambient air.

    摘要： A method for manufacturing or preparing thin-film stacks that exhibit moderate, finite, stress-dependent resistance and which can be incorporated into a transduction mechanism that enables simple, effective signal to be read out from a micro- or nano-mechanical structure. As the structure is driven, the resistance of the intermediate layers is modulated in tandem with the motion, and with suitable dc-bias, the motion is directly converted into detectable voltage. In general, detecting signal from MEMS or NEMS devices is difficult, especially using a method that is able to be integrated with standard electronics. The thin-film manufacturing or preparation technique described herein is therefore a technical advance in the field of MEMS/NEMS that could enable new applications as well as the ability to easily develop CMOS-MEMS integrated fabrication techniques. Also disclosed are: (i) transducers where current flows across a piezo layer from one major surface to the opposite major surface; and (ii) methods of making a transducer the resistivity of a piezoresistive layer is decreased and/or the gauge factor of a piezoresistive layer is increased.
