Dielectric Elastomer Actuator for Mechanical Loading of 2D Cell Cultures

Herbert Shea, Samuel Rosset, Alexandre Poulin

We demonstrate the use of dielectric elastomer actuators (DEAs) for mechanical stimulation of cells in vitro. The development of living tissues is regulated by their mechanical environment through the modification of fundamental cellular functions such as ...

Estimation of the Armature Leakage Reactance using the Constant Excitation Test

Basile Kawkabani

The adoption of the best available estimate for the stator Leakage reactance is the first step in several equivalent circuit of synchronous machine parameter estimation. However, there is no specific test for its direct measurement. This paper presents a s ...

Equivalent Admittance Approach for the Scattering of Patch/Slot-Based Frequency Selective Surfaces

Juan Ramon Mosig, Maria Garcia Vigueras

The equivalent admittance of a 2-D array of printed metallic patches/apertures is obtained here by extending a precedent equivalent circuit approach reported by some of the authors. The goal of the present extension is to cover more complex situations like ...

Bioengineering approaches to emulate the stem cell niche

Sylke Höhnel

Stem cell therapies hold tremendous potential for tissue and organ regeneration. Yet, there remains significant need for better ex vivo culture and manipulation methods. On the one hand, many tissue-specific stem cells cannot be propagated without causing ...

A cell engineering strategy to enhance the safety of stem cell therapies

Elisa Oricchio

The long-term risk of malignancy associated with stem cell therapies is a significant concern in the clinical application of this exciting technology. We report a cancer-selective strategy to enhance the safety of stem cell therapies. Briefly, using a cell ...

The in vitro expansion of hematopoietic stem cells (HSC) for clinical applications is hampered by a rapid loss of HSC blood reconstitution capability in culture. While these rare cells can be stimulated to massively proliferate, cell divisions mostly resul ...

We propose an equivalent longitudinal circuit to characterize surface plasmon polaritons (SPPs) propagation along spatially dispersive graphene parallel plate waveguides. This circuit allows the fast analysis of the propagating modes, taking into account t ...

The impedance of biological material changes with frequency, a phenomenon that has been discovered more than 100 years ago. It is due to the fact that the cell membrane acts as a capacitor which filters out currents at low frequency and lets them pass at h ...
