Abstract
In this work, conductive polyurethane (PU) foam is developed to be used as skin electrode for long term use medical devices. Water based polyurethane and other eco-friendly substances are selected to implement a green process, where the composite is produced in the shape of film and foam, by a transfer coating process. Different formulation and process materials are considered to evaluate the effect on surface resistivity and percolation threshold. The time stability, water vapor transmission, elongation and stress-strain properties, are studied. Results show that the realized material is suitable to be used as electrode for biomedical applications.
