Viscous damping of a periodic perforated MEMS microstructure when the Reynolds’ equation cannot be applied: Numerical simulations
This paper develops a computational model for determining the total damping coefficient for a unit cell of a MEMS microscale device containing a repetitive pattern of holes. The basic cell of the microstructure is approximated by an axi-symmetric domain and the velocity and pressure ... 詳細を見る
Expanding Your Materials Horizons
Materials and their related properties are intrinsically fundamental to the creation, development and solution of viable exploratory models when using numerical analysis software. In many cases, simply determining the location, availability and relative accuracy of the necessary material ... 詳細を見る
A Study of Lubricating Flows in MEMS Bearings
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 ... 詳細を見る
Contactless Excitation of MEMS Resonant Sensors by Electromagnetic Driving
A contactless electromagnetic principle for the excitation of mechanical vibrations in resonant structures has been investigated. The principle relies on no specific magnetic property of the resonator except electrical conductivity and can be adopted for employing the structures as ... 詳細を見る
Droplet Generation by Means of a Two-Fluid Probe
This paper presents a simulation of the operation of a new type of droplet generation probe. This probe, consisting of two concentrically-arranged tubings, is immersed in a beaker of cell medium so that oil is pumped through the outer tubing at a pumping speed less than fluid is drawn ... 詳細を見る
Control of Rolling Direction for Released Strained Wrinkled Nanomembrane
Strained wrinkled and flat nanomembranes have different bending properties when they are released from the underlying substrate. This is caused by increased bending rigidity of the wrinkled film in one direction. We provide theoretical and numerical analysis of the directional rolling of ... 詳細を見る
Thickness Optimization of a Piezoelectric Converter for Energy Harvesting
The conversion of mechanical energy from environmental vibrations into electrical energy is a key point for powering sensor nodes toward the development of autonomous sensor systems. Piezoelectric energy converters realized in a cantilever configuration are the most studied for this ... 詳細を見る
Multiphysics Modelling of a Micro Valve
Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the ... 詳細を見る
Modeling Flow of Magnetorheological Fluid through a Micro-channel
This paper presents the approach taken through the utilization of COMSOL Multiphysics 3.5a, to develop a model that simulates the flow of a magnetorheological (MR) fluid through a micro-channel. The model was developed as an aid in the analysis of a micropump that produces flow by means ... 詳細を見る
Analog to Digital Microfluidic Converter
This paper presents an Analog to Digital Microfluidic Converter (ADMC) using passive valves and enabling the conversion of a continuous liquid flow into droplets for Electro-Wetting On Dielectric (EWOD) actuation. Valves calibration, geometry characteristics and losses reduction have ... 詳細を見る
