In this work, the process of micro-channels in electrochemical micro-milling by using rotating magnet assisted helical tool is presented. The results show helical tool and Lorentz force of the rotating magnetic field that enhance the renewal of the electrolyte and machining efficiency. The feed rate can be raised under the magnetic field assisted in terms of experimental results; moreover, the ...

Porous Silicon (PS) can easily be formed by electrochemical etching of silicon in HF based electrolytes at room temperature. Since, PS is compatible with silicon IC technology; it finds lot of applications in the fabrication of MEMS devices. In the current study, we discuss the design of a condenser microphone using a Silicon/ Porous Silicon composite membrane as a movable plate. The performance ...

This paper gives an overview of modelling microsensors on geometry and system level. The focus will be on the generation of the multiphysics reduced order system model and the coupling with package and ASIC models. The method is based on modal superposition. This means all the details of the sensor can be considered in a finite element model. The mechanical mode shapes of this model form the ...

A single-crystal diamond NEMS switch was fabricated while batch production of SCD MEMS/NEMS structures were developed. The diamond NEMS switches exhibit high performance with respect to high controllability, high reproducibility, and good reliability. Modeling and simulations were made that were consistent with experiments.

There is urgent need to monitor dental and oral diseases, such as tooth decay, gum diseases, and teeth grinding. Such monitoring can be achieved by embedding sensors in the mouth. This technique faces some difficulties. The first is how the power needed for the operation of the sensors and the associated electronic chips can be generated. This power can be generated using the pressure exerted by ...

This paper will describe the dependence of capacitive accelerometer characteristics on the accelerometers physical dimension and its material properties. The sense element of the accelerometer is designed on the basis of a commercially available torsion based accelerometer technology. The sense element consists of an asymmetrically shaped flat plate of metal supported above a substrate surface by ...

The objective of the work is to propose a reliability enhancement model for antigen detection system (ADS) using bio MEMS based cantilever array sensors using heterogeneous modular redundancy technique. The reliability of the ADS is expressed in terms of the constituent sub systems which are heterogeneous not only in their respective structures and behaviors but also in their forms. The possible ...

: One of the most commonly used techniques for quantification of beating forces exerted by cardiomyocytes is culturing them on a bed of vertical microcantilevers or microposts. The position of the microcantilevers is observed through advanced imaging techniques and the displacements are observed over a period of time. The stiffness of the microcantilevers is known and thus the force can be ...

The oxidation behavior of metallic nanoparticles is investigated in respect to material parameters like Mott potential, defects on the microstructure and oxide volume increase per ionic defect. An emphasis is laid on magnetic nanoparticles where the degree of oxidation can be measured via the reduction of the magnetic moment.
