On the stability of polymeric electrochemical elements for adaptive networks

A polyaniline-polyethylene oxide hybrid electrochemical device was fabricated and its stability was studied analyzing cyclically acquired voltage-current characteristics. The results show reproducibility of data during a rather long working period (at least 4000 min). Such stability is adequate for the use of the polymeric electrochemical heterojunctions as key nodes of adaptive networks capable of 'intelligent response' to training procedures.
