Abstract: An electrode, the electrode including an exposed contact surface, the exposed surface comprising a contact material, the contact material comprising a MXene. A device, the device including a plurality of electrodes, each of the plurality of electrodes comprising an exposed contact surface, the exposed surface comprising a contact material, the contact material comprising a MXene. A method, the method including delivering electrical stimulation to a subject with an electrode that comprises an exposed contact surface, the exposed contact surface comprising a contact material that includes a MXene.

Abstract: Provided are enhanced MXene materials made from MAX-phase precursors that comprise an excess of metal A. The resultant enhanced MXenes exhibit improved stability over periods of days and months, particularly when stored in aqueous media.

Abstract: The present disclosure describes electrochromic devices comprising transparent conductive layer acting as an electrode, an active electrochromic film, an ion conductor, and an ion storage film at least one of which comprises at least one MXene material.

Abstract: Provided are electrodes that comprise MXene materials as well as related methods of using the disclosure electrodes in neural and other monitoring applications.
