Development and validation of process instructions for process integrated poling in series production as well as methods for poling of unstructured compound materials based on experiments characterising the material and simulations of the poling process.


  • Investigation of the poling behaviour under the influence of T, E, ϭ and t and resulting properties (d33, ε, kp) at operation temperature
  • Space- and time related simulation of large signal behaviour of piezoceramic components in functional structures and composite materials
  • Technologies for poling of unstructured composite materials
  • Verified design recommendations and poling technologies
  • Efficient new method for characterisation of the poling state
