Abstract

In recent years, the bioelectronics field has seen the use of an increasing variety of conducting polymers because they promise to display tunable mechanical properties (flexibility) and the ability to form an intimate interface with living tissue – in strong contrast to their inorganic counterparts. Even though transduction of ionic bio-signals into electronic signals is thought to be the key mechanism for successful integration of electronic devices in biological systems, little insight has so far been gained that allows understanding the interplay of electronic and ionic conductivity in the currently employed materials. Here we present a materials science approach to this challenge that promises to control mixed ionic/electronic transport in ‘plastics’ by blending organic semiconductors with insulating polymers and that assists to elucidate the two processes to establish relevant structure/processing/property interrelationships.
