Described herein are microelectrode devices to provide localized neural recording or neural stimulation to a neurological target. The device includes a plurality of electrodes disposed along the shafts of deployable flexible pins. The deployable flexible pins are enclosed within an elongated probe shaft, and can be expanded from their enclosure. Additionally, a specifically manufactured outer housing can be coupled to at least a portion of the elongated probe shaft. During deployment of the flexible pins the outer housing of the microelectrode device reduces friction between the flexible pins and the probe shaft and reduces delamination of the flexible pins during deployment.
