    Smart body-machine interfaces offer great potential for healthcare and consumer products. For effective merging of the body and machines, the necessary electronic hardware should be mechanically compatible, function stably within the body's dynamic environment, accurately capture and process body signals, learn from the body's reactions and act accordingly. Mixed ionic-electronic polymers are promising for this highly demanding task. They react to ions, changing their properties, which can then be used in applications. To date, the main hurdle is finding a material that balances ion movement with electronic movement.  In my lab at MIT lab (the Laboratory of Organic Materials for Smart Electronics, OMSE Lab), we focus on creating such materials. I will discuss how we design new semiconductors that respond differently to ions and how we tweak molecules for varied uses. One method we use is copolymerization, allowing us to produce a range of conductors suited for devices from quick electrochemical transistors to advanced artificial synapses. By adding polar groups to known good electronic conductors, we can study the balance of ionic and electronic movement and its impact on performance. I will also touch on our work in creating bio-compatible probes that combine sensing and brain-like signal processing.
