Electrode plates: Current Capacity Up to 10 mA

Q: What are electrode plates used for?

Electrode plates are used in applications like neural implants for brain stimulation, ECG/EKG sensors, industrial electrolysis, battery cells, and scientific research for signal acquisition or delivery.

Q: How do I choose materials for electrode plates?

Select materials based on application: platinum or iridium oxide for biocompatibility in medical devices, stainless steel for industrial durability, or carbon for cost-effective sensing. Consider factors like corrosion resistance and electrical properties.

Component Specifications

Definition

Electrode plates are flat, conductive elements typically arranged in arrays within electrode assemblies. They serve as interfaces for transmitting electrical signals to or from biological tissues, materials, or other media in applications such as neural stimulation, electrophysiology, electrochemical sensing, and industrial processes like electroplating or electrolysis. Their design ensures precise electrical contact and distribution.

Working Principle

Electrode plates operate by establishing an electrical interface between a circuit and a target medium. When voltage is applied, they facilitate current flow through ionic conduction (in biological or liquid environments) or electron transfer (in solid-state applications), enabling functions like signal recording, stimulation, or electrochemical reactions based on Faraday's laws.

Materials

Common materials include platinum, iridium oxide, stainless steel, titanium, gold, or carbon-based composites, chosen for conductivity, biocompatibility, corrosion resistance, and durability. Specifications may include purity grades (e.g., 99.95% platinum), surface coatings (e.g., PEDOT), or alloy compositions.
