We present a problem-adapted finite element model, which enables the design of a novel type of a highly miniaturized, electrostatic MEMS membrane pump, as well as the investigation and the optimization of its operation. The electro-mechanical actuation scheme constitutes a strongly ... Read More

Multiphysics Inertial Particle Focusing (IFP) Model Validated for 3D Microfluidic Geometries

G. Spinola Durante1, D. Bayat1
1CSEM SA (CH)

Inertial focusing of particles in a fluid flow is a physical effect induced by inertial forces already happening at the micro-fluidic scale. COMSOL Multiphysics® has provided an implementation of the drag and lift forces to compute this effect for a constant parallel-wall fluid channel ... Read More

Thermo-Electrical Improvement of a MEMS-IR-Emitter Membrane

Toni Schildhauer1, Andreas T. Winzer1
1CiS Forschungsinstitut für Mikrosensorik GmbH, Erfurt, Germany

NDIR (Non-dispersive infrared) sensors are state of the art for measuring gas concentrations in the Mid-infrared spectrum, e.g. components of exhaled human breath. These sensors require fitting light sources. Micro light bulbs and other filament based light source are sensible to ... Read More

Predictive Simulations of Warpage Phenomena on Arbitrarily Patterned Silicon Wafers

Filippo Sabatini1
1Politecnico di Milano, ST Microelectronics

In this simulation, we aim to comprehend the origin and mechanism of the warpage phenomenon in patterned silicon wafers, which are key components in the field of microelectronics. This issue can become more pronounced in the presence of high global density of the patterns and can lead to ... Read More
