Abstract

An electrode set is disclosed that has two separable parts including an assembled base with printed circuit board basement, biasing member and top cover and an electrode. The basement and top cover may be made by metal or conductive material.

Claims

1. An electrode set, comprising:

a base having a conductive biasing mechanism, an opening and a connection;

a conductive electrode having a cap portion and a post portion connected to the cap portion, the post portion having a retaining ridge;

the electrode is inserted into the opening of the base wherein the electrode is releasably retained in the base by the retaining ridge, the electrode is pivotable and rotatable in the opening of the base; and

wherein a signal detected by the electrode passes through the conductive electrode and the conductive biasing mechanism to the connection.

2. The electrode set of claim 1, wherein the conductive electrode is replaceable.

3. The electrode set of claim 1, wherein the conductive biasing mechanism further comprises a spring;

4. The electrode set of claim 3, wherein the base further comprises a basement, a set of circuits and a top cover connected to each other.
