A major challenge when creating interfaces for the nervous system is to translate between the signal carriers of the nervous system (ions and neurotransmitters) and those of conventional electronics (electrons).Organic conjugated polymers represent a unique class of materials that utilizes both electrons and ions as charge carriers. Based on these materials, we have established a series of novel communication...
An organic electronic ion pump, including poly(3,4-ethylenedioxythiophene) as the active material has been used to electronically control the transport of protons between two electrolytes and to change the pH of the target solution from 7 to 3 in a few minutes. The number of transported protons equals the time-integrated current between the two addressing electrodes. If no voltage is applied the leakage...
