A disposable electrode comprising an annulus of foam, a substantially uniform electrode gel in a central region of the annulus, a conductive layer in the electrode gel and making electrical contact with it, and a cap over the conductive layer, electrode gel and annulus of foam. The electrode is made in a plastic tray by placing said annulus in a recess in the tray, placing the conductive layer on the annulus, pouring hot electrode gel into the center region of the annulus, covering the gel with the cap and covering the tray with a sheet which is heat sealed to the tray with the electrode inside. |
