For the conventional Utah Electrode Array (UEA) to be able to function without transcutaneous wire connections, a kind of power source is needed in an integrated form with the UEA. To develop such wireless neural interfaces, inductive coupling between two coils was used to deliver power to the integrated electronics. The power receiver coil was microfabricated as a polymer based component, and its electrical characteristics and performance in power transmission were investigated in dry condition.
