This paper proposes the use of Electromechanical Brakes (EMB) in combination with regenerative braking in PHEV so braking force can be distributed to front and rear axles according to an optimal curve instead of a linear line. Therefore, more braking force will be distributed to front axle, which will offer more kinetic energy for regenerative braking. Fuzzy logic control is used to allocate br...

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...

We determined the electromechanical properties of a suspended graphene layer by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS) measurements, as well as computational simulations of the graphene-membrane mechanics and morphology. A graphene membrane was continuously deformed by controlling the competing interactions with a STM probe tip and the electric field from ...

Nanoelectromechanical systems were fabricated from single- and multilayer graphene sheets by mechanically exfoliating thin sheets from graphite over trenches in silicon oxide. Vibrations with fundamental resonant frequencies in the megahertz range are actuated either optically or electrically and detected optically by interferometry. We demonstrate room-temperature charge sensitivities down to ...

The relaxor based ferroelectric (1-x)Pb(Zn(1/3)Nb(2/3))O(3)-xPbTiO(3) and (1-x)Pb(Mg(1/3)Nb(2/3))O(3)-xPbTiO(3) single crystals provided new challenges in property characterization because their extraordinarily large piezoelectric coefficients and electromechanical coupling coefficients. Large errors may occur in some of the derived material constants using conventional characterization techniq...

We have studied thedielectric and electromechanical properties of pure and doped Pb(Zr0.53Ti0.47)O3thin films.Samples were prepared bya sol-gel method and werecalcined at temperatures of 700oC for two hours in a Pb-rich atmosphere.It was observed a negligible effect occurs during the tetragonal–rhombohedral transition in the preparedpure and doped PZT thin films.The optimal amount of electrical...

This work deals with the development and implementation of an electromechanical skeletal muscle model. To this end, a recently published hyperelastic constitutive muscle model with transversely isotropic characteristics, see Ehret et al. (2011), has been weakly coupled with Ohm's law describing the electric current. In contrast to the traditional way of active muscle modelling, this model is ro...

We report the design, fabrication and electromechanical performance of a newly developed micro electromechanical XYscanner for micro-optical spatial light modulation using the silicon micromachining technology. A two-dimensional stage is integrated with a silicon micro lens to scan a transmitting infrared light of 1.55-micronwavelength by the mechanism of the f -θ lens scanner. Mechanical displ...

Acute increase of intracranial pressure (ICP) usually has to be treated with an external ventricular drainage (EVD). Current standard mechanical EVD carry a lot of disadvantages, which hypothetically could be better managed by a newly developed electromechanical EVD. In this report our first preliminary results of such an electromechanical EVD applied in a porcine animal model are presented. Th...
