Detecting cutaneous electrode peeling using electrode-skin impedance

Abstract:

Apparatus for transcutaneous electrical nerve stimulation in a user, the apparatus comprising: stimulation means for electrically stimulating at least one nerve; an electrode array connectable to said stimulation means, said electrode array comprising a plurality of electrodes for electrical stimulation of the at least one nerve, said electrodes having a pre-formed geometry and known electrode-skin contact area size when in complete contact with the user's skin; monitoring means electrically connected to said stimulation means for monitoring the impedance of the electrical stimulation through said electrode array; and analysis means for analyzing said impedance to estimate a change in the electrode-skin contact area.
