Dynamic Observation of Magnetic Particles in Continuous Flow Devices by Tunneling Magnetoresistance Sensors

A. Weddemann[1], A. Auge[1], F. Wittbracht[1], C. Albon[1], and A. Hütten[1]

[1]Department of Physics, Thin Films and Physics of Nanostructures, Bielefeld University, Bielefeld, Germany

Dynamic measurement of magnetic particles in continuous flow devices is made very difficult by the limitations imposed by the sensors themselves. Thus, certain sensor layouts are restricted to either number sensitive or spatial resolutive measurements of magnetic particles. We ... En savoir plus

Multiphysics Modeling of Nanoparticle Detection - Current Status and Collaboration Sought

D. Krizaj[1], I. Iskra[2], Z. Topcagic[1], and M. Remskar[2]
[1]University of Ljubljana, Faculty of Electrical Engineering, Ljubljana, Slovenia
[2]Institut Jozef Stefan, Ljubljana, Slovenia

We are developing nanoparticle detector for airborn particles. The detection principle is based on condensation of nanoparticles forming micron sized water droplets and detection of the droplets by a capacitive type nanodetector. We have successfully performed some experimental ... En savoir plus

Simulation Driven Design of Blood Warmer

Rajesh K. [1], Sivakumar A [1],
[1] HCL Technologies, Chennai, Tamil Nadu, India

Blood Warmer is a movable instrument intended to deliver peripheral warmth to the arterial piping so as to keep the blood under warm conditions or liquid passing by throughout transfusion. The instrument is used to keep the blood or fluids under desired warm states before to transfusion ... En savoir plus

V. Tzanov [1], E. Ledesma [1], F. Torres [1], N. Barniol [1],
[1] Universitat Autonoma de Barcelona, Spain

Micromachined ultrasound transducers can work as a sensor or actuator for measuring fluid speed and direction, mixing and exciting particles (sonication), taking images (ultrasonography), non-destructive testing and many other purposes in various fields. In this work, a COMSOL ... En savoir plus

MEMS Based Silicon Load Cell for Weighing Applications

D. Chauhan[1], B. D. Pant[2]
[1]Kurukshetra University, Kurukshetra, Haryana, India
[2]CSIR- Central Electronics Engineering Research Institute, Pilani, Rajasthan, India

Load cells are force sensors, which are used in weighing equipment. The objective of this work is to develop MEMS based load cell. In this work two different load cell designs were simulated. First design is based on compressing a meander like polysilicon strain gage for the measurement ... En savoir plus
