Descripción del proyecto
Estudio sistemático de la dinámica de los polímeros electroactivos
Los polímeros electroactivos son materiales blandos inteligentes que cambia de tamaño o forma al ser estimulados por un campo eléctrico. Esta clase de material se usa comúnmente en accionadores, así como en recolectores de energía, dispositivos biomédicos, compuestos electrónicos flexibles y dispositivos resonadores sintonizables. Con todo, aún se carece de una comprensión sistemática de su comportamiento dinámico, lo que origina cuellos de botella para la innovación. El proyecto financiado con fondos europeos DYN-SEAM investigará a fondo cómo afectan determinados factores a la dinámica de los polímeros electroactivos. Gracias a la combinación de modelos teóricos con simulaciones numéricas y pruebas experimentales, el proyecto estudiará la inhomogeneidad, la anisotropía, la viscoelasticidad, las interacciones fluido-sólido y las estructuras periódicas de los polímeros electroactivos.
Objetivo
Dr. Bin Wu is a Chinese national, trained in Applied Mechanics and Multi-physics in China, Germany, and Italy. He is applying for a two-year MSCA Fellowship to conduct the DYN-SEAM action at NUI Galway, Ireland.
Due to striking advantages such as rapid response and large deformation under electric stimuli, and significant changes of dynamic characteristics induced by biasing fields (pre-stretch, electric stimuli, etc.), soft electro-active materials (SEAMs) have found multiple and practical applications in the real world, including actuators, energy harvesters, biomedical devices, flexible electronics, tunable resonators, and wave devices. However, a systematic understanding of their dynamic behaviours is still lacking, creating a bottleneck to innovation.
The action aims at conducting an in-depth investigation of the effects of key factors (inhomogeneity, anisotropy, viscoelasticity, fluid-solid interaction, periodic structures) on the dynamic characteristics of SEAMs under biasing fields, with special attention in exploring promising applications, such as ultrasonic non-destructive testing and ultrasound elastography, smart design of self-sensing actuators, tunable resonators, and soft intelligent wave devices.
The action mixes ad-hoc theoretical modelling with experimental tests and numerical simulations, by taking full advantage of the host and partner institutions' expertise and facilities, and experience in scientific management, intellectual property, etc. Secondments include a period at an acoustics laboratory (academic) and another at an enhanced hearing company (non-academic).
This international, inter-sectoral and inter-disciplinary action will enable novel technological advances in material/life science and engineering—contributing to Europe 2020 'Innovation Union' initiative and European excellence. It will allow the researcher to grow as a world-class leader for these emerging fields, with a unique blend of expertise and hands-on experience.
