The present invention provides a microelectrode, comprising a flexible layer, an electrically conductive layer and a plurality of platinum dendrite structures, wherein the electrically conductive layer is arranged in the flexible layer, and wherein on the surface of the flexible layer are a plurality of grooves within which the electrically conductive layer is revealed partially, and wherein each of the groove is provided with one platinum dendrite structure therein. The plurality of grooves serve as focal electrodes distributed uniformly, with smaller electrode sites and more recording points. The modified platinum dendrite structures increase the surface area, electrical performance, biocompatibility and service life of the microelectrode. Besides, creating virtual electrodes by current steering technique increases the number of stimuli received by microelectrode during use, and improves its resolution in applications.
