1. An electrochemical electrode for use in a biosensor, said electrode comprising:
a substrate comprising a flexible, electrically-non-conductive polymer film;
an electrically-conductive layer deposited on said substrate; and
an electrically-resistive material layer deposited on said conductive layer;
wherein said electrically-resistive material layer comprises amorphous carbon and at least one C—N species; and
wherein said C—N species is present in an amount of at least 20 atomic percentage based on the total electrically-resistive material layer.
