A method for exposing a microwire from it glass coating in a glass coated microwire. The method for exposing the microwire is facilitated by way of sufficiently bending the glass coated microwire to break the glass coating while maintaining the embedded microwire intact.

A visual implant (2) comprises an array of micro-electrodes (4) including at least two stimulation micro-electrodes each comprising: a core (106) of conducting material; insulating material (108) surrounding the core; and a layer (112) of metal or metal oxide nano-structures deposited on tips of the micro-electrodes at a front end for interfacing with a target site for visual stimulation; and an integrated circuit (6) to control a pattern of stimulation current driven through the array of micro-electrodes.
