Abstract

An electrocardiographic amorphous alloy electrode is manufactured from an iron-based (or nickel-based) amorphous alloy containing chromium as a metallic element and also containing at least one member of a group consisting of phosphorus, carbon, silicon and boron as a non-metallic element or semi-metallic elements.

Claims

1. An electrocardiographic electrode consisting of an iron-based amorphous alloy containing iron, chromium and molybdenum as metallic elements and at least one non-metallic element selected from the group consisting of phosphorus, carbon, silicon and boron, the content of molybdenum being less than 20 atomic percent, and the sum of the concentrations of molybdenum and chromium being from about 1 to about 35 atomic percent.

2. An electrocardiographic electrode according to claim 1 wherein said non-metallic element comprises phosphorus.

3. An electrocardiographic electrode according to claim 1 containing at least one member of the group consisting of phosphorus-carbon, phosphorus-silicon, phosphorus-boron and carbon-boron.

4. An electrocardiographic electrode according to claim 1 wherein said non-metallic element is present in a concentration from about 10 to about 25 atomic percent.

5. An electrocardiographic electrode according to claim 1 wherein the concentration of molybdenum is at least about 5 atomic percent, the concentration of chromium is at least about 10 atomic percent, and the remainder of the metallic elements is iron.

6. An electrocardiographic electrode according to claim 1 wherein the concentration of molybdenum is at least about 10 atomic percent, the concentration of chromium is at least about 5 atomic percent and the remainder of the metallic elements is iron.
