Design analysis of a large displacement and high force piezoelectric inchworm motor

Sofiane Ghenna, Yves Bernard, Laurent Daniel

This paper presents a design analysis of an inchworm motor for applications requiring high force and large displacement with fine resolution. The piezoelectric inchworm motors are inspired from the motion features of nature inchworm. The motor can achieve a long range motion by repeating a clamp-…

Facile growth of density- and diameter-controlled GaN nanobridges and their photodetector application

Jin-Ho Kang, Muhammad Ali Johar, Bandar Alshehri, El Hadj Dogheche, Sang-Wan Ryu

The growth of arrayed GaN nanobridges (NBs) and their application in a photodetector (PD) were studied. First, GaN nanowires (NWs) were selectively grown on the sidewalls of a GaN mesa using an Au catalyst-assisted vapor–liquid–solid (VLS) method, while their density was conveniently controlled by…

Substance P enhances lactic acid and tyramine production in Enterococcus faecalis V583 and promotes its cytotoxic effect on intestinal Caco-2/TC7 cells

Kelly Biaggini, Valérie Borrel, Sabine Szunerits, Rabah Boukherroub, Awa N’diaye, Arthur A. Zebre, Maryse Bonnin-Jusserand, Guillaume Duflos, Marc Feuilloley, Djamel Drider, Pierre Déchelotte, Nathalie Connil

Background: Enterococcus faecalis, generally considered as a saprophytic bowel commensal, has recently emerged as an important nosocomial pathogen causing severe urinary tract infections, surgical wound infections, bacteremia, and bacterial endocarditis. This bacterium is capable of forming bioflms…

Phononic Crystal Made of Multilayered Ridges on a Substrate for Rayleigh Waves Manipulation

Mourad Oudich, Bahram Djafari-Rouhani, Bernard Bonello, Yan Pennec, Frédéric Sarry

We present a phononic crystal to achieve efficient manipulation of surface acoustic waves (SAW). The structure is made of finite phononic micro-ridges arranged periodically in a substrate surface. Each ridge is constructed by staking silicon and tungsten layers so that it behaves as one-dimensional…

MIMO relaying networks for cooperative spectrum sensing: False alarm and detection probabilities

Imen Souid, Haithem Ben Chikha, Iyad Dayoub, Rabah Attia

In this paper, we investigate spectrum sensing in cooperative networks. Hence, in order to enhance cooperative sensing, we propose a novel model based on multiple-input multiple-output (MIMO) relaying broadcast channels with direct link and cognitive radio technology. Despite their efficiency in…
