This paper presents ongoing research aimed at development of a MEMS magnetometer capable of nanoTesla sensitivity. Such a device would pave the way for inertial-grade MEMS IMUs. A resonant sensor is proposed, based on a Xylophone Bar sense element, and is analysed both directly and via COMSOL. Mode shapes and frequencies are found as functions of geometric parameters, and the results used ...
In recent years, optical manipulation using optical radiation pressure has been widely studied. In this study, the radiation pressure exerted on various kinds of microscopic objects with different laser beams was evaluated by COMSOL Multiphysics software. By changing beam shapes, microscopic objects can be trapped and rotated. This paper is in Japanese.

This paper describes the characteristics of MEMS microchannel and various issues of its designing. Here the major parameters are pressure drop and heat transfer rate. Various structures are modeled and optimized to get a minimum pressure drop and maximum heat transfer rate. The simulation results provide the characterization for Temperature, Mass flow rate, Pressure drop and Reynolds number. Here ...

In this research, we performed multiple COMSOL Multiphysics® simulations. We analyzed the dispersion curves of waves in a LAMB wave pressure sensor; simulated a thin metal film in a microbolometer and observed the resulting stress; investigated the thermal behavior of an acoustic wave microbolometer; and modeled the fluid-structure interaction (FSI) for piezoelectric-based energy harvesting from ...

Optical tweezers work on the idea of non-contact Optical Pressure felt by transparent particles, when shined by coherent light source such as lasers. On the other hand when light falls on the metal it excites the electron inside it and make them free. When these free electron cloud moving in an harmonic frequency it satisfies the resonance condition called surface plasmon resonance (SPR). We ...

The paper presents a method of extraction of coupling of modes (COM) parameters for a one port surface acoustic wave (SAW) resonator from the results of finite element analysis in COMSOL Multiphysics®. The COM parameters calculated are electromechanical coupling coefficient, reflection coefficient, and SAW phase velocity. In addition, the quality factor of the SAW resonator is determined. The ...

By introducing a periodic modulation in a waveguide, it is possible to create an interaction between forward-traveling and backward-traveling modes of an optical waveguide. Bragg grating may be a one dimensional diffraction grating which diffracts light from the forward-traveling mode into the backward traveling mode. Since the Bragg grating reflects at the wavelength for which it is ...

Large deflection actuators are becoming increasingly important for microsystems. Since actuation forces are usually small, large deflection actuators usually require flexures with low stiffness. Rectangular serpentine flexures are often used for such actuators due to their low stiffness and large linear deflection range. In this paper we investigate the performance of curved serpentine flexures ...

The bearing and shaft are part of a safe and arm device constructed as an assembly by a multi-layer additive/subtractive plating and planarization processes (EFAB technology). Devices are constructed by a multi-layer additive/subtractive planarization process. This paper evaluates the lubricating flow between the shaft and journal of the MEMS bearing for seven configurations. The pressure ...
