A05 - Dielectric characterisation of cells, tissues and materials
Summary of the work programme
The dielectric properties of cells and tissues determine their response to electrical stimulation. Electrical characteristics will be investigated in project A05 by dielectric spectroscopy. The initial objectives are the description of trabecular bone, the evaluation of electrode interfaces, including coatings, and the assessment of bone cell growth on surfaces. The goal is to eventually develop dielectric measurements towards a non-invasive method that allows monitoring of the integration of implants with respect to patient-specific differences. Future work also aims to apply methods and procedures towards other tissue types, such as cartilage, and the detailed assessment of stimulation parameters with respect to the development of exposed cells.
