Patent ID: 7103398

Claim:
An electrical signal sensing and/or signal application device for sensing electrical signals on a surface and/or for applying electrical signals to a surface, of human or animal skin or other biological organs or tissues, comprising a substrate having first and second major surfaces, a plurality of electrodes arranged on the first major surface of said substrate and projecting therefrom, each of said electrodes comprising a pointed contact end facing away from said substrate for contacting the surface, and a base end facing towards said substrate, and a plurality of first contact pads arranged on said first or second or both major surfaces of said substrate for electrical connection to contact elements of an evaluation and/or driving means for evaluating the sensed electric signals and/or applying signals to said electrodes, said first contact pads being electrically connected to said electrodes, wherein said first major surface of said substrate comprises, for each electrode, a second contact pad, said base ends of said electrodes being electrically and mechanically connected to said second contact pads, and wherein each electrode is generated by bonding an electrically conductive bonding wire to a second contact pad for generating a thickened socket portion of said electrode comprising its base end, and by tearing the bonded bonding wire off the socket portion so as to generate a pointed portion of said electrode comprising its pointed contact end and projecting from the socket portion thereof.
