Conductive Element Component – Computer, Electronic and Optical Product Manufacturing

Q: What is the primary function of a conductive element in biopotential electrodes?

To transmit bioelectrical signals from biological tissues to monitoring equipment with minimal signal loss and noise.

Q: Why is silver/silver chloride commonly used in conductive elements?

Ag/AgCl provides stable half-cell potential, low impedance, and minimal polarization, ensuring accurate signal acquisition in medical applications.

Component Specifications

Definition

A conductive element is the core component of biopotential electrodes, designed to establish stable electrical contact with biological tissues (skin, muscle, nerve) to capture and transmit weak bioelectrical signals (ECG, EEG, EMG) to amplification and recording systems with minimal noise and impedance.

Working Principle

Works by creating an ionic-to-electronic current conversion interface: ions from biological tissues interact with the conductive surface, generating electrical currents that are transmitted through the element to monitoring equipment, facilitated by electrode gels or direct contact to reduce skin impedance.

Materials

Silver/silver chloride (Ag/AgCl) for high conductivity and stability, stainless steel for durability, conductive polymers (PEDOT:PSS) for flexibility, or gold-plated surfaces for low-noise applications.

Technical Parameters

Size Diameter 5-30 mm
Lifespan >1000 uses
Impedance <5 kΩ at 10 Hz
