Conception et modélisation d'un micro-actionneur à base d'élastomère diélectrique by Sofiane Soulimane( Book )

2 editions published in 2010 in French and held by 2 WorldCat member libraries worldwide

Polymer materials have been proposed to be good candidates for the development of new actuators. Due to their tunable mechanical and electrical properties, they can be used as electro-active devices. In this manuscript, we focus on dielectric elastomers based actuators, and word toward establishing innovative and alternative integration/miniaturization processes inspired from microelectronics and MEMS technology. Dielectric elastomer actuators are made of an elastomer dielectric layer sandwiched between two conductive electrodes. Upon voltage application attraction forces between the electrodes generates a mechanical displacement correlated with the elastomer Young modulus and permittivity. After a complete review of polymer materials as electro-active actuators, we propose to use the polydimethylesiloxane (PDMS) due to its high elasticity and its permittivity made adjustable by addition of ceramic nanoparticles. A original process for structuring PDMS layers is developed to overcomes the technological challenges encountered during the integration of such materials in a micro-actuator. In addition, several method of characterization allowed us to better understand the physicochemical mechanisms involved at different technological steps for both the material alone or mixed with Titanate of Baryum nanoparticles. We also measured the permittivity and the elasticity modulus of these materials at the end of the manufacturing process thereby verifying the concervation and the enhancement of the initial properties that set our choice. In parallel the response of our actuator is analyzed quantitatively by implementing a finite element model with the Comsol software, and by modeling the elastomer response with hyper elastic models. We show excellent correlation between the model and experimental deformations. Moreover, we determine that the thinness, hence the deformability, of the upper electrode guaranties high performances to the manufactured micro-actuator, and we conduct preliminary tests with a compliant electrode obtained with the PEDOT-PSS conductive polymer
