Hydrogels and conductive hydrogels for implantable bioelectronics

Stéphanie Lacour, Outman Akouissi, Emilio Fernández Lavado, Massimo Mariello, Kutay Sagdic

Hydrogels are a class of soft materials, which display unique biomimetic properties to biological tissues. Their mechanical properties, high water content, and porosity resemble that of extracellular matrix so that cell growth and proliferation can be reli ...

On the behavior of uniaxial static stress loaded micro-scale fused silica beams at room temperature

Yves Bellouard, Christos Edouardos Athanasiou, Saood Ibni Nazir

The question of whether static stress in fused silica relaxes at room temperature is still under debate. Here, we report experimental data investigating the behavior of fused silica at room temperature when subjected to static tensile stress up to 2 GPa st ...

Folded-Tube Soft Pneumatic Actuators for Bending

Wyatt Marshall Felt

This article presents a model and experimental results for a new class of bending soft pneumatic actuators (SPAs) made from a single section of thin-walled flexible tubing. The actuator is formed by creasing the tubing into fin-like rectangular folds and i ...

Compressible and Electrically Conducting Fibers for Large‐Area Sensing of Pressures

Pedro Miguel Nunes Pereira de Almeida Reis, Fabien Sorin, Alexis Gérald Page, Yunpeng Qu, Andreas Leber, Dong Yan, Shahrzad Shadman Yazdi

Flexible pressure sensors offer a wide application range in health monitoring and human–machine interaction. However, their implementation in functional textiles and wearable electronics is limited because existing devices are usually small, 0D elements, a ...

Modeling Vacuum Bellows Soft Pneumatic Actuators with Optimal Mechanical Performance

Jamie Paik, Matthew Aaron Robertson, Wyatt Marshall Felt

This paper presents the concept and model of "Vacuum Bellows," a cylindrical membrane-reinforced contractile vacuum soft pneumatic actuator (V-SPAs). These actuators consist of a tubular membrane connected to a series of interior rigid rings periodically s ...

Probing ice VII crystallization from amorphous NaCl-D2O solutions at gigapascal pressures

Livia Eleonora Bove Kado

We probe the possible inclusion of salt (NaCl) in the ice VII lattice over the pressure range from 2 to 4 gigapascal. We combine data from neutron diffraction experiments under pressure and from computational structure searches based on density functional ...

Numerical Simulation of the RF Plasma Discharge in the Linac4 H- Ion Source

Minh Quang Tran, Stefano Mattei

This paper presents a Particle-In-Cell Monte Carlo Collision simulation of the Radio-Frequency (RF) plasma heating in the Linac4 H- ion source at CERN. The model self-consistently takes into account the electromagnetic field generated by the RF coil, the e ...

Long-Term Development of Thermophysical and Mechanical Properties of Cold-Curing Structural Adhesives Due to Post-Curing

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Omar Moussa

The long-term changes in the thermophysical and mechanical properties of a cold-curing structural epoxy adhesive were investigated by accelerating the curing reaction by post-curing at elevated temperatures. Experimental data concerning the glass transitio ...

Mechanical and electronic properties of vanadium oxide nanotubes

László Forró, Arnaud Magrez, Andras Kis, Balazs Sipos, Jin Won Seo, Martial Duchamp, Neven Barisic

Vanadium oxide nanotubes with a diameter of 20-100 nm and an aspect ratio of 50-100 were synthesized by hydrothermal method. Young's modulus of 20-80 GPa was obtained by bending measurements of individual nanotubes using an atomic force microscope. Electri ...

Side-Information Scalable Source Coding

Suhas Diggavi

We consider the problem of side-information scalable (SI-scalable) source coding, where the encoder constructs a two-layer description, such that the receiver with high quality side information will be able to use only the first layer to reconstruct the so ...
