Researchers have been looking for alternatives of expensive conventional accelerometers in vibration measurements. Micro-ElectroMechanical Systems (MEMS) accelerometer is one of the available options. Here the performance of one of these MEMS accelerometers compared with a well known commercial accelerometer.

This paper discusses a MEMS implementation of a planar Van de Graaff generator in a standard MUMPs process. The ability to generate high voltages in autonomous MEMS devices may be useful in various applications such as Smart Dust [1].

This newly formed center is part of an overall set of centers on MEMS/NEMS fundamentals supported by DARPA. The MITOSU-HP Focus Center aims to develop new methods for fabrication of MEMS and NEMS that do not use conventional lithographic methods. The Center leverages the leading expertise of MIT and OSU in MEMS and printed devices, with the printing expertise of HP. The focus center is organize...

This paper presents a study of RF MEMS switch designed to be integrated in tunable filters for applications from W-frequency band to V-frequency band. Along the whole process, we go into detail of each procedure to present a complete study from design to fabrication and characterization of a RF-MEMS switch. The proposed concepts are validated by experimental results.

Background and purpose: Medical errors are one of the most common threats to patient safety. Medication errors have a number of consequences, including the increase in patient mortality, length of stay, and healthcare costs. Materials and Methods: This study was conducted by Food and Drug Deputy of Mazandaran University on medication errors reported received from covered hospitals during 201...

Within the past decade, researchers in the field of tissue engineering have recognized the need for newmaterials with soft and elastic properties. As a result, many groups have focused on the synthesis, characterization, and application of materials with a wide range of biodegradable and elastomeric properties.1 The combination of these polymers with Micro–Electro–Mechanical Systems (MEMS) tech...

Although it is challenging to implement follower forces in macroscale laboratory experiments, they can be implemented fairly easily in MEMS devices. This paper discusses the implementation of follower and axial end forces in a beam-type MEMS resonator for the application of resonant frequency tuning. r 2005 Elsevier Ltd. All rights reserved.

The singular parabolic problem ut = ∆u − λf(x) (1+u)2 on a bounded domain Ω of R with Dirichlet boundary conditions, models the dynamic deflection of an elastic membrane in a simple electrostatic Micro-Electromechanical System (MEMS) device. In this paper, we analyze and estimate the quenching time of the elastic membrane in terms of the applied voltage —represented here by λ. As a byproduct, w...

Reliable operation of a miniaturized mechanical system requires that nanomechanical motion be transduced into electrical signals (and vice versa) with high fidelity and in a robust manner. Progress in transducer technologies is expected to impact numerous emerging and future applications of microand, especially, nanoelectromechanical systems (MEMS and NEMS); furthermore, high-precision measurem...
