Patent ID: 8694070

Claim:
A system for recording of an electroencephalographic potential, an evoked potential, and ground and reference potentials in electroencephalographic and evoked potential measurements, said system comprising: (a) a resilient electrode having an initial configuration and a deformed configuration, said electrode having an edge carrying sharp points; (b) electroencephalograph equipment; (c) a lead wire connectable to said electroencephalograph equipment and to said electrode, said electrode being adapted to send electrical signals through said lead wire to said electroencephalograph equipment; and (d) an applicator having a recess formed therein to hold said electrode in said deformed configuration and a hole in registration with said recess through which said electrode can pass from said applicator when said electrode is in said deformed configuration so that, when said applicator is held against skin of a patient, and said electrode has been urged from said recess and through said hole, said electrode springs resiliently from said deformed configuration to said initial configuration as said electrode exits said hole thereby embedding said sharp points into said skin of said patient.
