Claims (18)

A device having an electrically conductive member having a contact surface that is a surface of a surface region of a conductive member and having a contact surface constituting a contact material, wherein at least 70 atomic% of the contact material is composed of nickel and hydrogen, wherein the hydrogen is Electrical contact element, characterized in that it is present in a substantially small percentage in quantity to enhance electrical contact properties of the contact surface. 2. The electrical contact element of claim 1 wherein the hydrogen atoms in the contact material correspond to nickel atoms in a potential state. The electrical contact element according to claim 1, wherein the surface region is an electrodeposition layer having an atomic concentration of hydrogen in the amount of about 0.0004 to 0.0009. 2. The electrical contact element of claim 1 wherein the surface region is a layer that is elastically deformed with a concentration of hydrogen in the amount of 0.0004 to 0.01. 5. The electrical contact element of claim 4 wherein the surface area is elastically deformed to result in a cross-sectional area reduction of at least 50%. The electrical contact element of claim 1 wherein the contact resistance at the surface is less than or equal to 100 milliohms. An electrical contact element as claimed in claim 1 wherein said contact surface is substantially the entire surface of said member. 8. The electrical contact element as claimed in claim 7, wherein said member is a contact pin. 8. The electrical contact element according to claim 7, wherein said member is conductive particles. 10. The electrical contact element of claim 9 wherein the particles are ink particles. 10. The electrical contact element of claim 9, wherein the particles are embedded in a nonconductive matrix material. 12. The electrical contact element of claim 11 wherein the non-conductive matrix material is an adhesive material. The electrical contact element of claim 1 wherein the contact material has a surface coating comprised of gold, one or several platinum group elements, and a coating material selected from the group consisting of gold and one or various platinum group elements. 14. The electrical contact element of claim 13 wherein the amount of coating material is sufficient to provide a surface model of the coating material. 14. The electrical contact element of claim 13, wherein said surface coating has a thickness of 0.01 to 0.05 micrometers. A method of fabricating a contact element having an electrically conductive member, wherein the member comprises providing a contact surface that is a surface of a surface region of a contact material, the surface area of the contact material having at least 70% atomic amount of nickel and hydrogen. And wherein said hydrogen is present in said amount at a significantly lower percentage, thereby making said contact material to enhance contact properties of said contact surface. 17. The method of claim 16 wherein said step is carried out by diffusing, sputtering or electrodepositing hydrogen into nickel. 18. The method of manufacturing the electrical contact element according to claim 17, wherein the member is cold worked before diffusion. ※ Note: The disclosure is based on the initial application.
