Low Cost Vibration Measuring Device Using MEMS Accelerometer

Pandiyan J., Umapathy M., Balachandar S., Arumugam M., Ramaswamy S., Larsen & Toubro Limited, IN

This paper presents the design of an acceleration sensing transmitter using Micro Electro Mechanical System (MEMS) capacitive accelerometer. It describes the accelerometer sensor interfacing circuit, rms-to-dc converter and voltage to current loop converter circuit design, [...]

Tuning of a MEMS RF Filter

Hammad B.K., Abdel-Rahman E.M., Nayfeh A.H., Virginia Polytechnic Institute and State University, US

We present an analytical model and use it to find closed-form expressions describing the response of a tunable MEMS RF filter. The filter is made of two identical clamped-clamped micro-beams suspended over input and output [...]

Building an Effective Patent Portfolio

Itchkawitz B.S., KNOBBE, MARTENS, OLSON & BEAR LLP, US

Effective patent portfolios provide a competitive advantage to high-tech companies by (i) protecting the company’s core technologies or “crown jewels,” (ii) defining areas of exclusivity and barriers to entry to the marketplace by competitors, (iii) [...]

MEMS-based solid propellant micro-rocket with micro-igniter on thin membrane for next generation of low-cost small space and aeronautic engines

Chaalane A., Rossi C., Estève D., LAAS/CNRS, FR

In this work, a new planar structure of solid propellant micro-rocket, for microspacecraft and Micro-Air-Vehicle applications is reported. These applications require extremely low levels of thrust and impulse in a very sort time. We have [...]

The Dynamic Performance of a Micro-machined Coriolis Flow Meter

Clark C., Wang S., Cheesewright R., Brunel University, UK

The dynamic performance of micro-machined Coriolis flow meters Summary The performance of a prototype MEMS mass-flow meter developed by ISSYS was investigated using the Brunel University Virtual Coriolis Meter facility. The flow meter comprises a vacuum sealed [...]

A Bio-Inspired Rotor Powered by a Micro-Bubble

Kao J., Warren J., Xu J., Attinger D., Columbia University, US

We present and characterize a novel micro-rotor actuation concept, where acoustic oscillations of a micro-bubble produce a steady fluid flow driving a microfabricated rotor at a rotating speed as high as 600 rpm. Developing micro-machines [...]

Optical Micro-Spectrometer with Sub-Nanometer Resolution

Avrutsky I., Chaganti K., Salakhutdinov I., Auner G., Wayne State University, US

We develop a super compact optical fluorescence spectrometer. Our unique innovative design combines advantages of guided wave planar optics and free-space microoptics. This innovation allows for miniaturization that is not achievable with pure planar or [...]

A Novel Optical Waveguide Based Accelerometer

Chen F., Salcic Z., Wang J., The University of Auckland, NZ

A novel accelerometer proposed in this paper utilizes desired advantages which waveguide structure has as its sensor, such as high sensitivity due to photoelastic effect and wide spectral response range. It extends previous research by [...]

A Nano-Scale Module with Full Spin-Wave Interconnectivity for Integrated Circuits

Eshaghian-Wilner M.M., Khitun A., Navab S., Wang K.L., UCLA, US

In this paper, we present a nanoscale computational architecture for integrated circuits where the nodes intercommunicate using Spin Waves. The key advantage of the proposed architecture is that the information transmission is accomplished without charge [...]

Approximate Pattern Matching in Nanotechnology

Annampedu V., Wagh M.D., Agere Systems Inc., US

Approximate pattern matching is comparing an unknown pattern with a database of stored patterns with a specified error tolerance. This ability to compensate for real world sensor errors makes approximate pattern matching an ideal choice [...]
