The electrical signal sensing and/or signal application device for sensing electrical signals on a surface and/or for applying electrical signals to a surface, particularly of human or animal skin or other organs or tissues, comprises a substrate ( 12 ) having first and second major surfaces ( 14 ), and a plurality of electrodes ( 16 ) arranged on the first major surface ( 14 ) of the substrate ( 12 ) and projecting therefrom, each of the electrodes ( 16 ) comprising a pointed contact end ( 36 ) facing away from the substrate ( 12 ) for contacting the surface, and a base end ( 26 ) facing towards the substrate ( 12 ). On the first or second or both major surfaces ( 14 ) of the substrate ( 12 ) there is arranged a plurality of first contact pads ( 22 ) for electrical connection to contact elements of an evaluation and/or driving means for evaluating the sensed electric signals and/or applying signals to the electrodes ( 16 ), the first contact pads ( 22 ) being electrically connected to the electrodes ( 16 ). The first major surface ( 14 ) of the substrate ( 12 ) comprises, for each electrode ( 16 ), a second contact pad ( 18 ) the base ends ( 26 ) of the electrodes electrically and mechanically connected to the second contact pads ( 18 ). Each electrode ( 18 ) is generated by bonding an electrically conductive bonding wire to a second contact pad ( 18 ) for generating a thickened socket portion ( 24 ) of the electrode comprising its base end ( 26 ), and by tearing the bonded bonding wire off the socket portion ( 24 ) so as to generate a pointed portion ( 34 ) of the electrode ( 16 ) comprising its pointed contact end ( 36 ) and projecting from the socket portion ( 24 ) thereof.
