OMIEC, organic mixed ionic-electronic conductors for energy storage, electrochromic displays, bioelectronics, sensors, electrocatalysis, neuromorphic devices, thermoelectrics, and actuators

by

Mixed ionic-electronic conductors, also known as mixed conductors, are an increasingly important category of materials with applications in energy storage, electrochromic displays, bioelectronics, sensors, electrocatalysis, neuromorphic devices, thermoelectrics, and actuators.

Mixed conductors exhibit both ion and electron/hole conductivity, and ionic-electronic coupling (i.e., capacitance), allowing them to effectively transduce ionic signals to electronic ones, and vice versa.

In recent years, new mixed conductors have been developed beyond the traditional metals oxides and phosphates to include (semi)conducting polymers, radical polymers, perovskites, and hybrid organic-inorganic materials, enabling improved performance and new functionalities.

Structured below are examples of polymeric mixed conductors from 1-Material Inc.

Organic Mixed Ion-Electron Conductor (OMIEC):

PE2-OE polymers: Incorporation of the unfunctionalized biEDOT unit increases backbone planarity and overall electroactive polymer content, ultimately delivers low operational voltages, high transconductance, and promising pulsing stability;  thereby deeming PE2-OE-based devices of high interest for the detection of biological events and amplifying signals for electrophysiological recordings.
