Abstract:
This thesis describes the open-loop behavior of an ionic polymer metal composite (IPMC) strip as a novel actuator, the empirical force and position models, the control system and the improved dynamic characteristics with the feedback control implemented. Ionic polymer metal composite is a novel polymer in the class of electroactive polymers. IPMC consists of a base polymer coated with electrodes made up of highly conducting pure metals such as gold. The actuation behavior of IPMC can be attributed to the bending of an IPMC strip upon application of voltage across its thickness. The main reason

Abstract:
Ionic Polymer Metal Composite (IPMC) is a class of electroactive polymer , that is receiving great attention due to its advantages of large bending deflection, low power consumption and driving voltage. Although there is still no commercial application of IPMC, it has been actively investigated by researchers for the past decade. The IPMC has been identified as a potential material to be used in the specific application of sensor and/or actuation, such as microgripper and micropump. This research deals with the characterisation of small scale IPMC with the ultimate objective to develop a simpl

Quantum Tunnelling Composite (QTC) is a metal polymer composite, commercialised and produced using a patented manufacture process.

This structure provides unique electronic behaviour including very high resistivity, of order 10 ΜΩ, above the expected percolation threshold and an exponential increase in conductivity under all types of mechanical deformation.

Abstract:
Ionic polymer-metal composites (IPMCs) are widely studied for their potential as electromechanical sensors and actuators. Bending of the IMPC depends on internal ion motion under an electric potential, and the addition of an ionic liquid and ionic self-assembled multilayer (ISAM) conductive network composite (CNC) strongly enhances bending and improves lifetime.

An increasing need for smaller, higher-power-density devices is driving the development of more advanced topologies for use in power architectures. The challenge, however, is to reduce the size of the passive components in circuit boards (e.g., the inductors), which are typically the most bulky. There are two ways to approach this problem. The first is to redesign the flux in the inductor in order to minimize its size; the second is to optimize the magnetic properties of the constituent magnetic materials, which include permeability, density, resistivity, core loss density, saturation magnetiz

A novel metal-polymer composite is presented, comprised of a micron-sized nickel powder dispersed within a silicone polymer matrix. The composite is intrinsically electrically insulating, but displays a dramatic increase in conductivity under compression, tension and torsion. The electrical response to applied compression is characterised. Combined with electron microscopy, the large sensitivity to compression is shown to be due to the uniquely spiky morphology of the filler particles. Low mechanical energy mixing techniques are essential for retaining these sharp tips. In addition, wetting of

Ionic polymer transducers (IPTs) are soft sensors and actuators which operate through a coupling of micro-scale chemical, electrical, and mechanical mechanisms. The use of ionic liquid as solvent for an IPT has been shown to dramatically increase transducer lifetime in free-air use, while also allowing for higher applied voltages without electrolysis. This work aims to further the understanding of the dominant mechanisms of IPT actuation and how these are affected when an ionic liquid is used as solvent.

Abstract:
L'industrie de l'aimant permanent est en pleine expansion et notamment celle des aimants lies a matrice polymere. Ces derniers presentent certains avantages par rapport aux aimants frittes (formes plus complexes, meilleure resistance aux chocs, prix plus faibles) qui les destinent a des applications de grandes distributions comme l'automobile, l'electromenager ne comportant pas d'etape de frittage au cours de son procede d'elaboration, le plastoaimant a ses proprietes magnetiques fixees par celles de la poudre qui le constitue. C'est pourquoi, la poudre utilisee doit avoir une forte coercivite

Abstract:
La sensibilité des méthodes acoustiques non-linéaires à la présence ainsi qu'à l'évolution des microendommagements a été prouvée dans différents travaux sur une large gamme de matériaux. Parmi les méthodes appliquées figure la résonance non-linéaire dont la sensibilité à l'endommagement est prouvée pour un seul mode de vibration à travers la décroissance de la fréquence de résonance ƒ et celle facteur de qualité Q en fonction de la déformation dynamique. Ainsi, les paramètres non-linéaires hystérétiques (NLH) ƒ et Q ne sont connus que dans une gamme fréquentielle réduite. Le présent travai

Abstract:
Nanocomposites of polyethylene and metal oxide nanoparticles have shown to be a feasible approachto the next generation of insulation in high voltage direct current cables. In order to reach an operationvoltage of 1 MV new insulation materials with reduced conductivity and increased breakdown strengthas compared to modern low-density polyethylene (LDPE) is needed.In this work polyethylene MgO nanocomposites for electrical insulation has been produced andcharacterized both from an electrical and material perspective. The MgO nanoparticles weresynthesized into polycrystalline nanoparticles with
