Outline of Final Research Achievements |
We have succeeded in developing a technique to laminate the composite of conducting polymer PEDOT and polyurethan (PEDOT-PU) onto hydrogel substrates by the novel interfacial photo-initiated radical polymerization of the polymer of adhesion layer. This technique enable the lamination of even the insulated PEDOT-PU electrodes, improving the accuracy and sensitivity on the medical use. In addition the possible function of self-immobilization to organs was demonstrated by using the PEDOT-PU-laminated hydrogel devices. As an example, the the expansion force of the gel substrate showed self-fixing to the gaps of brain. The curling force of the gel sheet showed self-wrapping to a neuronal bundle.
