1. A biosensor capable of receiving bioelectric stimulation or bio-signals, the biosensor having a pillar-type electrode structure coated with a non-conductive material, the biosensor comprising:
an electrode substrate; and
an electrode structure having a plurality of pillar electrodes protruding on the substrate;
wherein at least one or more of the plurality of pillar electrodes are coated with the non-conductive material and at least a portion of a side surface of each of the coated pillar electrodes is coated with the non-conductive material,
wherein the plurality of pillar electrodes are spaced apart from each other with an empty space therebetween,
wherein a height of the plurality of pillar electrodes protruding in the empty space is greater than a height of the plurality of pillar electrodes between the electrode substrate and the empty space,
wherein a coating height on the side surfaces of at least one of the plurality of pillar electrodes is a same as the electrode height, and
wherein a coating height on the side surfaces of at least one of the plurality of pillar electrodes is lower than the electrode height.
