Abstract: An implant system includes an electrode portion comprising plural electrodes to perform nerve stimulation and nerve sensing, an impedance controller configured to selectively connect the plural electrodes between a stimulator to perform nerve stimulation and a sensor to perform nerve sensing based on a control signal, and set an impedance of each of the plural electrodes, and a processor configured to control a contact impedance by the plural electrodes by generating the control signal to control at least one of plural switches connected respectively to the plural electrodes, or variable resistors connected respectively to the plural electrodes, based on at least one of a selectively set purpose of the plural electrodes or a position of an electrode to which nerve stimulation is to be provided.
