A New Photomechanical Molecular Switch Based on a Linear π-Conjugated System

Stéphane Lenfant, Yannick Viero, Christophe Krzeminski, Dominique Vuillaume, Dora Demeter, I. L. Dobra, Maiténa Oçafrain, Philippe Blanchard, Jean Roncali, C. van Dick, Jérôme Cornil

We report the electron-transport properties of a new photoaddressable molecular switch. The switching process relies on a new concept based on linear π-conjugated dynamic systems, in which the geometry and, hence, the electronic properties of an oligothiophene chain can be reversibly modified by…

Top-down Approach for the Direct Synthesis, Patterning, and Operation of Artificial Micromuscles on Flexible Substrates

Ali Maziz, Cedric Plesse, Caroline Soyer, Eric Cattan, Frederic Vidal

Recent progress in the field of microsystems on flexible substrates raises the need for alternatives to the stiffness of classical actuation technologies. This paper reports a top-down process to microfabricate soft conducting polymer actuators on substrates on which they ultimately operate. The…

High temperature gradient micro-sensor for wall shear stress and flow direction measurements, Micro-capteur à fort gradient de température pour des mesures de frottement pariétal et de direction de l'écoulement

Cécile Ghouila-Houri, J. Claudel, J.C. Gerbedoen, Q. Gallas, E. Garnier, A. Merlen, R. Viard, Abdelkrim Talbi, Philippe Pernod

We present an efficient and high-sensitive thermal micro-sensor for near wall flow parameters measurements. By combining substrate-free wire structure and mechanical support using silicon oxide micro-bridges, the sensor achieves a high temperature gradient, with wires reaching 1 mm long for only 3…
