A Two-Wired High Input Impedance and High CMRR Active Electrode Insensitive to Component Mismatch

Alexandre Schmid, Mehdi Saberi

This article proposes a new two-wired amplifying active electrode (AE), presenting a high input impedance and a high common-mode rejection ratio (CMRR). In the proposed structure, the input impedance and the CMRR of the system are considerably increased by ...

Portable Multi-Frequency Impedance-Sensing Device for Bacteria Classification in a Flowing Liquid

Sandro Carrara, Karim Bouzid

This paper presents a novel impedance-sensing device and its related microfluidics system developed to characterize the macroscopical properties of bacteria and microparticles. The system is based on a phase-sensitive detector with square-waves excitation ...

IEEE2022

Welding of steel plates is accompanied by residual stresses that increase as the constraint provided by the welded components becomes greater. Consequently, crack initiation has been reported after welding thick plates due to the high residual stresses dev ...

Impedance Analyser - Non-Linear Inductors and Capacitors Measurement

Impedance analyzers are essential equipment's for any engineer working in the domain of electrical circuits. The impedance of a circuit is determined by exciting this later with a sine voltage over a frequency span and by observing the current consequently ...

2019

The joining by welding processes of components is usually related to the creation of additional notches and geometrical peculiarities. Multiple investigations have shown that a clear correlation between the local weld geometry and the fatigue life of welde ...

Healing cracks in selective laser melting by 3D laser shock peening

Roland Logé, Christian Leinenbach, Jamasp Jhabvala, Nikola Kalentics, Navid Sohrabi, Hossein Ghasemi Tabasi, Andreas Burn

Selective Laser Melting (SLM) of Ni-based superalloys such as CM247LC is prone to weld-cracking. This paper investigates how to suppress cracks by repeatedly applying Laser Shock Peening (LSP) during the building phase of SLM. Samples made of CM247LC were ...

On the Optimisation of Multi-Degree-of-Freedom Acoustic Impedances of Low-Frequency Electroacoustic Absorbers for Room Modal Equalisation

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar

Low-frequency electroacoustic absorbers have recently been developed as a solution for the modal equalisation. Firstly investigated in waveguides, the technique consists in matching the acoustic impedance at a closed-box loudspeaker diaphragm to the charac ...

Label-free identification of activated T lymphocytes through tridimensional microsensors on chip

Carlotta Guiducci, George Coukos, Enrico Tenaglia, Elena Bianchi, Enrica Rollo, Alexandre Harari

Label-free approaches to assess cell properties ideally suit the requirements of cell-based therapeutics, since they permit to characterize cells with minimal perturbation and manipulation, at the benefit of sample recovery and re-employment for treatment. ...
