  implants establish information exchange between electronics and tissues o
 f the nervous system. Depending on the therapeutic context\, they can be i
 mplanted in the brain\, spinal cord or peripheral nerves. Traditionally\, 
 electrodes are made from stiff materials such as metals or silicon because
  of their favorable conductive and electrochemical properties. From a mech
 anical perspective\, electrodes are very different from the soft and hydra
 ted host tissues. This is implicated as a cause for sub-optimal biointegra
 tion\, especially when long-term implantation is required.  We are interes
 ted in new materials with which to make electrodes more tissue-like. In th
 is talk\, I will present our efforts to incorporate the conductive polymer
  PEDOT within synthetic hydrogels with elastic moduli similar to those of 
 neural tissues. Using an in situ polymerization approach\, we have achieve
 d electrical conductivity of up to 10 S/m which is maintained at strains e
 xceeding 200%. As a first step towards device fabrication\, we used rheolo
 gy modifiers to make our material compatible with 3D printing technologies
 . Our next steps concern the functionalization of the conductive hydrogel 
 with artificial extracellular matrix and its integration in electrode arra
 ys. I will also discuss a new project in our group. We aim to build device
 s that enable interaction with the nervous system in several \"languages\"
 . The special feature here is that neural tissue is treated not only as an
  electrical\, but also as a chemical\, thermal and optical machine. We wil
 l combine sensing and actuation modules in an integrated implantable techn
 ology to investigate the combined effects of multimodal neuromodulation.
