Polymeric Nanowire Architectures and Nanodevices

Liu H., Kameoka J., Verbridge S., Craighead H.G., Cornell University, US
We devised a method, named as scanned electrospinning technique, to form a variety of one-dimensional polymeric nanostructures. It is a straightforward technique that enables the rapid fabrication of oriented polymeric nanowires as well as their [...]

Frequency Stability and Noise Characteristics of Ultra-High Frequency (UHF) Nanoelectromechanical Resonators

Feng X.L., Roukes M.L., California Institute of Technology, US
Nanoelectromechanical systems (NEMS) are emerging as great candidates for a variety of technological applications ranging from sensors and actuators to signal processing and communications [1]. Nanofabricated high-frequency (often in the VHF/UHF bands) electromechanical resonators (i.e., [...]

On the Air Damping of Micro-Resonators in the Free-Molecular Region

Hutcherson S., Ye W., Georgia Institute of Technology, US
Predicting air damping on micromachined mechanical resonators is crucial in the design of high-performance filters used in wireless communication systems. In the past, most of the work focused on devices with minimum feature size on [...]

Air Damping in an Ultra-High-Frequency Disk Resonator

Yap L.K., Yap L.Y., Yap L.K., Yap L.Y., Ye W., Georgia Institute of Technology, US
In this paper we investigate the air damping in a circular disk radially oscillating at 1GHz. First the compressibility effects of air between the disk and the substrate are studied. The pressure perturbation along the [...]

Design and Simulation of a MicroElectroMechanical Resonator Oscillator

Parlak M., Naseer M., Gurbuz Y., Sabanci University, TR
MicroElectroMechanical (MEM) vibrating structures such as linear drive resonators can be used as driving components in signal processing applications. The choice of these components is assisted by the fact that these MEM devices display high [...]

In this paper we investigate the air damping in a circular disk radially oscillating at 1GHz. First the compressibility effects of air between the disk and the substrate are studied. The pressure perturbation along the [...]

Analysis of the Nonlinear Behavior of a MEMS Variable Capacitor

Innocent M., Wambacq P., Donnay S., Tilmans H., Engels M., DeMan H., Sansen W., IMEC, BE
Today’s wireless communication systems often require a high linearity for the RF building blocks. One of these blocks can be a tunable LC filter using MEMS variable capacitors (varicaps). In these filters, the varicaps are [...]

Micromechanical Pierce Oscillator for Resonant Sensing Applications

Seshia A.A., Low W., Bhave S.A., Howe R.T., Montague S., University of California, US
We present the design techniques and experimental characterization of a Pierce oscillator circuit adapted for micromechanical elements with resonant frequencies lying between 100 and 300 kHz. Micromechanical double-ended tuning fork resonators serve as the crystal [...]

Simulation and Characterization of High Q Microresonators Fabricated by UV – LIGA

Basrour S., Majjad H., Coudevylle J.R., Coudevylle J.R., de Labachèlerie M., CNRS, FR
This paper is devoted to a study on a new metallic microresonator realized by UV-LIGA technique. This device is excited electrostatically and takes advantage of the contour modes or Lamé-modes of the structure. Design methods [...]

Air-damping Effect on a Micro- and Nano-machined Beam Resonator

Xu G., Zhang C., Jiang Q., University of California, US
The air-damping effect on the resonant frequency and the quality factor of a micro- and nano-machined beam resonator is studied. The beam, placed in a uniform magnetic field, is driven to vibrate transversely by the [...]
