Improving the interface between electrodes and human tissue

Amplicoat® optimizes the interface between human tissue and the electrode through lower impedance, improved signal fidelity, increased charge injection capacity, lower power requirements and reduced stimulation threshold.

Amplicoat® can enable electrode miniaturization, to provide higher electrode density, greater tissue-sensing resolution and more localized stimulation control.

Amplicoat® is:

  • Used clinically on FDA-cleared and CE-Mark-approved devices
  • A proprietary, ISO 10993 biocompatible, durable conductive coating for electrodes
  • Available for commercialization and licensing for medical devices
  • Manufactured under an ISO 13485-certified quality system

Heraeus’ electro-conductive polymer coatings can be applied to a variety of medical electrode materials, including:

  • Platinum
  • MP35N®
  • Iridium
  • Gold
  • Titanium
  • Tungsten
  • Stainless Steel
  • Nitinol
  • Silicon

Amplicoat® is deposited via electrodeposition. This quick, safe and easy process can accommodate components or assemblies.

Amplicoat® is ideal for medical-device applications where electrode sensitivity and signal fidelity are critical, including:

  • Electrophysiology mapping
  • Neuromodulation
  • Cardiac Rhythm Management (CRM)

From cardiac rhythm management to electrophysiology, the ability to sense electrical impulses within the heart while providing safe and effective targeted treatment is critical for next generation devices. Some of the specific potential benefits of Amplicoat cardiac and neuro applications include:

  • Reduced electrical impedance
  • Improved neural and cardiac signal quality and reduced noise
  • Improved stimulation safety and efficiency
  • Reduced electrode polarization; improved power efficiency
  • Enables electrode miniaturization
  • Mechanical flexibility
  • Durability in physiological environments

There is a growing and continued interest in the development of new implantable medical devices that rely on electrical communication for the monitoring and treatment of a wide variety of health conditions.  Amplicoat offers improved sensing and stimulation performance for electrodes used in retinal and cochlear prostheses, deep brain stimulation, spinal cord stimulation, peripheral nerve stimulation, cardiac rhythm management, electrophysiology and biosensors.
