Summary:For biomedical electronics the compatibility to the biological environment should be well-considered. Therefore this paper evaluates dispensed carbon nanotubes (CNT's) on polyimide (PI) foil for conductive tracks and electrodes for flexible, biomedical applications. A CNT based ink is investigated regarding biocompatibility, flexibility, conductivity and suitability for electrode materials with contact to artificial body fluids. The testing methods comprise bending tests with resistance monitoring, adhesion tests and the utilization of dynamic fluidic and electrical load on dispensed structures. The CNT ink showed good bending properties up to 2653 cycles with an average sheet resistance of 32.5 Ohm/sq. A demonstration of biocompatibility using the adherent cell line HFFF2 resulted negatively. No delamination or dissolving effects occurred during exposure to 0.9 % sodium chloride solution.
