Product Specifications

Technical details and manufacturing context for Biopotential Electrodes

Definition
Biopotential electrodes are critical components within physiological sensor arrays that interface directly with biological tissues to capture electrical signals such as ECG, EEG, EMG, and EOG. They convert ionic currents in the body into electronic currents measurable by monitoring equipment.
Working Principle
Biopotential electrodes operate based on electrochemical principles at the electrode-tissue interface. They establish electrical contact with the body, where ionic conduction in biological fluids is transduced into electronic conduction in the electrode material through charge transfer reactions, allowing measurement of voltage differences generated by physiological processes.
Common Materials
Silver/Silver Chloride (Ag/AgCl), Stainless Steel, Gold, Conductive Hydrogel
Technical Parameters
  • Electrode-skin impedance, typically ranging from 1kΩ to 100kΩ depending on electrode type and skin preparation (Ω) Per Request
Components / BOM
  • Electrode Body/Backing
    Provides structural support and houses conductive elements, often with adhesive for skin attachment
    Material: Medical-grade foam or flexible polymer
  • Conductive Element
    Primary interface for electrical signal transduction, typically a metal disc or mesh
    Material: Silver/Silver Chloride, Stainless Steel, or Gold
  • Conductive Gel/Hydrogel
    Improves electrical contact between electrode and skin by reducing impedance and maintaining moisture
    Material: Electrolyte-infused hydrogel or saline-based gel
  • Lead Wire/Connector
    Transmits captured electrical signals from electrode to monitoring equipment
    Material: Insulated copper wire with snap or pin connector

Downstream Applications
Specialized Tooling

Application Fit & Sizing Matrix

Operational Limits
pressure: Atmospheric pressure only (non-invasive application)
other spec: Humidity: 30-80% RH, Impedance: <5 kΩ at 10 Hz, Shelf life: 12-24 months
temperature: 0°C to 40°C (operational), -20°C to 60°C (storage)
Media Compatibility
✓ Human skin (ECG/EEG/EMG applications) ✓ Animal tissue (veterinary/research use) ✓ Aqueous electrolyte gels (conductive interface)
Unsuitable: High electromagnetic interference environments (MRI suites, arc welding areas)
Sizing Data Required
  • Target biological signal frequency range (Hz)
  • Required electrode contact area (cm²)
  • Application duration (short-term vs. long-term monitoring)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Signal Drift or Instability
Cause: Degradation of the electrode-skin interface due to drying of conductive gel, accumulation of skin oils/debris, or poor adhesion leading to inconsistent impedance and motion artifacts.
High Impedance or Signal Loss
Cause: Corrosion or oxidation of the electrode metal (e.g., silver/silver chloride), delamination of the conductive layer, or cable/connector damage disrupting electrical continuity.
Maintenance Indicators
  • Visual: Visible discoloration, cracking, or flaking of the electrode surface or conductive adhesive.
  • Audible/Operational: Intermittent or persistent noise (e.g., baseline wander, 60Hz hum) in the monitoring system's audio or visual output, indicating poor contact or electrical interference.
Engineering Tips
  • Tip 1: Implement a strict electrode rotation and replacement schedule based on usage hours or cycles, and store electrodes in sealed, humidity-controlled packaging to prevent premature drying or contamination.
  • Tip 2: Use skin preparation protocols (e.g., gentle abrasion, alcohol cleaning) to reduce impedance, and apply consistent, moderate pressure during placement to ensure stable adhesion without damaging the electrode layers.
