Electrochemically controlled polymeric device: a memristor (and more)   found two years ago
  We report the fabrication and properties of a polymeric memristor, i.e. an electronic element with memory of its previous history. We show how this element can be viewed as a functional analog of a synaptic junction and how it can be used as a critical node in adaptive networks capable of bioinspired intelligent signal processing.
