Resumo: | Bioelectronics is a field still in development that will have a positive impact in individuals’ life worldwide creating promises and excitement. The organic materials “soft” nature offers better mechanical compatibility with tissue than traditional electronic materials, and have natural com-patibility with mechanically flexible substrates. One of those organic materials, PEDOT:PSS, has emerged in recent years as a champion material in some applications such as artificial muscles and as bending actuators for autofocus micro lens applications. This work aims at the research and production of thin electroactive membranes that are able to bend at a when applying a certain electrical potential across it, the study of its electrical and mechanical properties, a study about the influence from the process parameters and the in-vestigation of the electromechanical devices durability, reliability and reproducibility. The elec-tromechanical device PEDOT:PSS/PVDF obtained the best results, showing a low voltage actu-ation, mechanical strength of 40 MPa. |
