Paper Abstract

Electronic devices comprising biocompatible materials will open the pathway to a whole new field of future applications ranging from healthcare and medicine to smart packaging and disposable electronics. In this work we present the fabrication of light-emitting electrochemical cells comprising a non-halogenated bio-friendly solid-polymer electrolyte on biodegradable cellulose di-acetate substrates by industrially relevant printing techniques. By using a biocompatible electrode system consisting of PEDOT:PSS and ZnO we could produce functional devices comprising up to 99 vol% of biocompatible materials. The devices are semi-transparent and flexible even under operation. A maximum luminance of over 200 cd m-2 is achieved significant for display and lightning applications. The relatively short lifetime on the timescale of some minutes can be compensated by a fully-printed production process utilizing inkjet printing and blade coating, relevant for an industrially cost-efficient large-scale production of disposable electronics.
