A Comparative Investigation of Deformation Transducers Based on Bacterial Cellulose and Different Ionic Liquids

The development of green sensors and transducers has been a response to the need for environmentally friendly devices for various applications such as biomedical, environment monitoring, and water purification, to name a few. In this paper, we propose an analysis concerning the generation capabilities of bacterial cellulose transduction elements based of variegated families of ionic liquids. The investigations are conducted on bacterial cellulose compounds, impregnated with ionic liquids, and coated on both sides with PEDOT:PSS conducting polymers. The absence of ionic liquids is also addressed to evaluate the improvement induced by ionic liquids. The results evince the suitability of the transduction elements, and the performances are outlined in terms of current generation and natural frequency as a function of the selected ionic liquids.
