[1]Universidad de los Andes, Bogotá, Colombia

A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital ... Mehr lesen

Modeling Partially Absorbing Biosensors

D. Kappe[1], A. Hütten[1]
[1]Bielefeld University, Bielefeld, Germany

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 ... Mehr lesen

Simulations of Micropumps Based on Tilted Flexible Structures new
