Development and validation of a dielectric-elastomer-based artificial urinary sphincter

Yves Perriard, Yoan René Cyrille Civet, Paolo Germano, Armando Matthieu Walter, Quentin Philippe Mario De Menech, Andres Osorio Salazar, Marc Michel Charles Favier

This study presents the development and experimental validation of an artificial urinary sphincter (AUS) based on dielectric elastomer actuators (DEAs) for the treatment of urinary incontinence. Traditional AUS devices are often mechanically complex, prone ...

Thermally-Drawn Multi-Electrode Fibers for Bipolar Electrochemistry and Magnified Electrochemical Imaging

Fabien Sorin

Imaging systems using closed bipolar electrode (cBPE) arrays and electrochemiluminescence (ECL) have attracted great attention in recent years as a 2D imaging platform with high spatiotemporal resolution. However, the fabrication techniques for cBPE arrays ...

Fiber fuse in chalcogenide photonic crystal fibers

Camille Sophie Brès, Jianqi Hu, Svyatoslav Kharitonov, Sida Xing

We observe fiber fuse in tapered GeAsSe photonic crystal fibers (PCF) at around 7 MW∕cm2 of intra-core intensity. Vertically cleaved facets from the un-tapered regions and the tapered regions were imaged. The images show shallow voids of different shapes c ...

Numerical simulation of two-dimensional in-plane crack propagation in FRP laminates

Thomas Keller, Anastasios Vassilopoulos, Aida Cameselle Molares

A numerical investigation was carried out in order to simulate experimental results previously obtained concerning two-dimensional (2D) in-plane crack propagation in laminated glass fiber-reinforced polymer (GFRP) plates. The laminated plates were designed ...

Functional composites with damage control and repair

Amaël Maximilien Cohades

Fibre Reinforced Polymer (FRP) composite structures are subjected during service to low energy impacts or unexpected loads, leading to damage. Microcracks are generally first formed in the matrix and can reach up to several hundred microns in thickness. In ...

Confocal microscopy via multimode fibers: fluorescence bandwidth

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie

We recently described a method for confocal reflection imaging through fibers, as a way to increase contrast when imaging unstained biological specimens. Using a transmission matrix, focused spots can be created at the distal end of a fiber. The backscatte ...

Modelling of fatigue behaviour of bridge deck slab elements strengthened with reinforced UHPFRC

Eugen Brühwiler, Tohru Makita

With the occurrence of higher and more frequent axle loads on roads, in particular bridge deck slabs are more severely solicitated by fatigue loading. To avoid heavy interventions for strengthening of deck slabs, an improved building material is used, name ...

Parylene C Coated Microelectrodes For Scanning Electrochemical Microscopy

Hubert Girault, Pekka Eero Peljo, Fernando Cortes Salazar, Haiqiang Deng

Herein, we present a simple microelectrode preparation methodology consisting in coating a platinum wire or a carbon fiber with a thin insulating Parylene C film (e.g. 1–10 μm), to produce SECM probes with a small and constant probe RG (i.e. ratio between ...

High Temperature Behavior of Nano-Structured Ceramic Composites Studied by Mechanical Spectroscopy

Mehdi Mazaheri

Silicon nitride based ceramics (SiAlONs); tetragonal polycrystalline zirconia (3Y‐TZP); alumina and their composites reinforced with different amount of multi‐ walled carbon‐nanotubes (CNTs) have been processed by Spark Plasma Sintering (SPS). High tempera ...

Punching shear strength of steel fibre reinforced concrete slabs

Luis Felipe Maya Duque, Aurelio Muttoni, Miguel Fernández Ruiz

The ultimate strength of reinforced concrete slabs is frequently governed by the punching shear capacity, which may be increased with addition of traditional fitments such as reinforcing steel, headed studs or shear heads. In addition to these traditional ...

Probabilistic strength prediction for double lap joints composed of pultruded GFRP profiles, part II: Strength prediction

Thomas Keller, Till Vallée

A probabilistic method for the strength prediction of adhesively bonded double lap joints composed of pultruded GFRP adherends subjected to quasi-static axial tensile loading is presented. The prediction method is based on the experimentally determined mat ...
