Dynamics of ion transport in a bio-derived ionic transistor

Biological processes and electromechanical function in ionic polymers share ion transport as the fundamental processes for sensing, actuation and energy harvesting. Inspired by the similarity in protein-bound cell membranes and polypyrrole membrane (an ionic polymer), our group is developing a hybrid device that provides the template for integrating biology and electronics. The integrated device, referred to as a bio-derived ionic transistor (BIT), consists of a bilayer lipid membrane (BLM) formed on a polypyrrole membrane and has two inputs that regulates the output of the device. This proceedings article will discuss the constructional features of proposed actuator, fabrication procedure of a prototype actuator and discuss a modeling framework for analyzing the dynamics of the ionic response.
