Advanced Conductive Polymer Technologies

Improve your products with advanced conductive polymer technologies found only at Heraeus.

The advanced conductive polymer technologies offered by Heraeus include two commercial products recently added to our portfolio: AmplicoatTM and TecticoatTM.

These technologies are targeted to provide device developers and manufacturers with an improved materials toolset to enable breakthrough solutions.

Amplicoat is intended for medical applications inside the body such as catheters and leads for cardiac and neural applications. It can be applied to a range of electrode substrate materials and offers device processing flexibility.

Tecticoat, on the other hand, is intended for applications outside the body, e.g. EEG, ECG, EMG and wearables. It can be applied to any material — whether conductive or nonconductive, rigid or flexible — and transform it into a conductive material.

Improving the interface between electrodes and human tissue

AmplicoatTM 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.

AmplicoatTM 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.

Improved Sensing and smaller Electrodes Amplicoat TM

AmplicoatTM improves the interface between electrodes and human tissue. Additional benefits include:

  • Low electrode impedance
  • High charge injection capabilities

High performance conductive coatings for functional wearables

TecticoatTM is a conductive polymer-based coating that can be deposited onto a wide variety of textiles and materials to create high performance electrodes for wearable devices.

  • Tecticoat is flexible, durable and ideal for skin-contacting applications.
  • The coating can be applied by multiple methods allowing customizability for specific applications and the ability to coat complex geometries and pattern traces or other features.
  • Tecticoat can be used to create custom electrogram-recording electrodes and sensors out of a variety of materials.
  • Next generation smart textiles are enabled by allowing textile designers to incorporate electrical or ionic conductivity into the fabric itself.
  • Tecticoat overcomes many common issues with traditional electrodes including wet gels, laborious skin preparations and variable performance under differing environments.
  • Tecticoat is deposited via printing, dip or spray coating. These processes are safe, customizable and highly scalable.
  • Heraeus offers development, prototyping and manufacturing capabilities. We work collaboratively with our customers and partners to bring products from concept to market.

The most common uses for TecticoatTM are wearable devices for physiological monitoring, bioelectrical stimulation, and biosensors.

Tecticoat enables new therapies and patient monitoring capabilities by providing polymer-based electrodes that:

  • Improve skin-electrode interfacing leading to faster signal acquisition
  • Eliminate the need for gels, adhesives and wet conductivity enhancers
  • Are soft, flexible and conformable
  • Have high electrical conductivity

Potential applications for Tecticoat include devices for the treatment, diagnosis, and/or monitoring of neurological or cardiovascular conditions:

  • Dry EEG electrodes/sensors
  • Cardiac monitoring with ECG or HR
  • Rehabilitation wearables (e.g., stimulation, EMG)
  • Bypass of neural deficits caused by disease (e.g., NMES, Neuroprosthetics)
  • Relief devices (e.g., TENS)
  • Health and fitness monitoring

Tecticoat allows for adding conductive elements to almost any object including textiles and 3D-printed objects
