Component Specifications

Definition
A specialized electrical component in biopotential electrodes that serves as the conductive pathway between the electrode-skin interface and medical monitoring devices. It consists of insulated wires terminated with connectors designed to maintain signal integrity while minimizing noise, interference, and motion artifacts during physiological measurements.
Working Principle
Functions as a low-impedance transmission line for bioelectrical signals (typically microvolt to millivolt range) by providing shielded conductive paths that preserve signal fidelity through proper insulation, grounding, and connector design to prevent electromagnetic interference and ensure patient safety.
Materials
Conductor: Tinned copper or silver-plated copper wire (24-30 AWG). Insulation: Medical-grade PVC, silicone rubber, or TPE. Shielding: Aluminum foil or braided copper with drain wire. Connector contacts: Gold-plated brass or stainless steel. Housing: ABS plastic or polycarbonate.
Technical Parameters
  • Impedance <100 Ω
  • Cable Length Standard 1.2m, 1.8m, 3m

Frequently Asked Questions

What is the difference between shielded and unshielded lead wires?

Shielded wires have an additional conductive layer (foil or braid) that reduces electromagnetic interference, essential for low-amplitude biopotential signals. Unshielded wires are simpler but more susceptible to noise.

How often should lead wires be replaced?

Typically every 6-12 months with regular use, or when signs of wear, cracking, or intermittent connections appear. Follow manufacturer guidelines and hospital protocols.

Can lead wires be sterilized?

Most are designed for surface disinfection only. Check manufacturer specifications; some medical-grade materials tolerate specific sterilization methods like ethylene oxide or low-temperature plasma.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
