Phase Corrected H-Plane Horn Antenna in Gap SIW Technology

Juan Ramon Mosig, Marc Esquius Morote, Lei Wang

This communication introduces a modified substrate integrated waveguide (SIW), the gap SIW, and deduces an approximate closed-form expression for calculating its effective width, taking into account the fringing and coupling fields around the gap. As an im ...

Electrical impedance tomography: Amplitudes of cardiac related impedance changes in the lung are highly position dependent

Michael Graf

Background Electrical impedance tomography (EIT) is used on the thorax to measure impedance changes due to the presence of air and blood in the lung. This experimental study was performed to investigate the effect of posture on cardiac and respiratory rela ...

3D multi-layer probe for application in neuroprosthetics

Diego Ghezzi, Marta Jole Ildelfonsa Airaghi Leccardi, Vivien Gaillet, Bastien Duckert

In neuroprosthetics, prostheses with higher and denser electrodes are needed to obtain both more precise recordings and targeted stimulations. The main limit is the routing of the active sites to the electronic control unit. A solution is to place electrod ...

Ultrathin Alumina Membranes as Scaffold for Epithelial Cell Culture from the Intestine of Rainbow Trout

Philippe Renaud, Kristin Schirmer, Songmei Wu, Carolin Drieschner

Permeable membranes are indispensable for in vitro epithelial barrier models. However, currently available polymer-based membranes are low in porosity and relatively thick, resulting in a limited permeability and unrealistic culture conditions. In this stu ...

Stability Considerations for Variable Impedance Control

Aude Billard, Klas Jonas Alfred Kronander

Impedance control is a commonly used control architecture for robotic manipulation. For increased flexibility, the impedance can be programmed to vary during the task. This has important implications on the stability properties of the control system, which ...

Low-energy biomarker detection through charge-based impedance measurements

Mihai Adrian Ionescu, Junrui Zhang, Marco Mazza

A novel approach for the detection of biomarkers in aqueous condition via differential impedance is presented. The binding of biomarkers onto functionalized inter-digital electrodes induces a change in the sensor impedance, both in its real and imaginary c ...
