Dielectrophoresis (DEP) is a method for cell manipulation without physical contact in lab-on-chip devices, since it exploits the dielectric properties of cells suspended in a microfluidic sample, under the action of locally generated high-gradient electric fields. The DEP platform that has been developed offers an integrated solution for customizable applications. Several functional units, ...

A wireless passive pressure sensor and the measurement system were design and simulated using COMSOL 4.3. The sensor is based on MEMS capacitor attached to a planar inductor for wireless powering and readout. An external coil is used for the measuring system. The pressure to be measured compresses the MEMS capacitor and changes sensor\'s resonance frequency. COMSOL 4.3 was used for the analysis ...

Designing and constructing a lab-on-a-chip device poses a variety of questions. Transport of all required substances, detection of the analyte and its deposition on a sensor have to be incorporated. Different strategies have been developed to achieve good coverages of the sensor, like employing electric or magnetic gradients. On the basis of a ramp like structure, the binding of the analyte to a ...

The transducer's construction used for current measurement in medium voltage power lines for current values kA is shown. The transducer involves magnetic circuit with a gap in which a MEMS structure with a movable cantilever is placed. The beam is made of silicon with a NiFe layer. The beam with the ferromagnetic layer is deflected due to effecting magnetic field. The deflection of the beam is ...

This poster focuses on the development of a capacitive pressure sensor for condition monitoring applications. One method to measure vibrations is to mount an pressure sensor on the vibrating machinery or object and measure the pressure exerted due to vibrations. Measured pressure level helps to detect any deviations from the normal conditions.

A patch antenna based on metamaterials of composite split-ring-resonators (CSRRs) and strip gaps is designed with COMSOL Multiphysics® software. The antenna is constructed by using CSRR structures in forms of circular rings on the patch and employing strip gaps on the ground plane. The signal is fed by a common microstrip line that connects the patch and the input port. The antenna is based on a ...

Modeling of 3D AC electro-osmotic pumps is relevant to the creation of portable or implantable lab-on-a-chip devices for mm/s tunable fluid flows attainable with battery scale voltages. In this analysis using COMSOL Multiphysics we investigate the modeling challenges of computationally calculating systems of fluid flow phenomena governed by AC Electroosmosis in the micro and nano scale regimes.

The variability of the design parameters caused by material properties like thermal conductivity is the major challenge in Micro Electromechanical System (MEMS). In resonator design the basic problem is that the frequency changes with temperature variation and quantitative explanation with respect to this varies. The change can be attributed to the stability in terms of frequency drift in parts ...
