Component Specifications

Definition
The electrode body/backing is a critical component in biopotential electrodes, serving as the physical substrate that holds the conductive elements (like silver/silver chloride) and provides structural integrity. It ensures proper skin contact, electrical isolation from external interference, and comfortable adhesion during physiological signal acquisition (ECG, EEG, EMG). The backing material must be biocompatible, flexible, and moisture-resistant to maintain signal quality and patient safety.
Working Principle
The electrode body/backing works by providing a stable platform for the conductive gel and sensing element, ensuring consistent skin-electrode interface. It minimizes motion artifacts by maintaining adhesion, isolates electrical signals from environmental noise, and supports the electrode's shape during application. The backing's dielectric properties prevent short circuits and enhance signal fidelity by reducing interference from external electromagnetic sources.
Materials
Medical-grade polymers such as polyurethane, polyethylene, or silicone rubber; often combined with adhesive layers (hydrogel or acrylic) and conductive elements (Ag/AgCl). Materials must meet ISO 10993 biocompatibility standards.
Technical Parameters
  • Thickness 0.1-0.5 mm
  • Flexibility Conforms to skin curvature
  • Biocompatibility ISO 10993 certified
  • Adhesion Strength ≥ 0.5 N/cm
  • Dielectric Strength ≥ 5 kV/mm
Standards
ISO 10993, ISO 13485, ASTM D1000, IEC 60601
