We report on the fabrication and characterization of a new generation of electro-switchable optofluidic devices, based on flexible substrates, combined with the extraordinary properties of reconfigurable soft-materials. A conductive polydimethylsiloxane microstructure has been first sputtered with an Indium Tin Oxide layer and then functionalized with an amorphous film of SiOx; then, the “layer” by “layer” microstructure has been infiltrated with an anisotropic and reconfigurable fluid (Nematic Liquid Crystal, NLC). The sample has been characterized in terms of morphological, optical and electro-optical properties: the soft-conductive microstructure exhibits a uniform and regular morphology also after testing with mechanical stretching and deformations. Combination of the conductive ITO with the functionalization film (which has been employed for inducing in-plane alignment of NLC molecules) enables to carry out a series of optical and electro-optical experiments; these confirm excellent properties in terms of reconfigurable device and diffractive element as well.
