Composite material for biocompatible soft electronics

Composite material for biocompatible soft electronics

This technology is a biocompatible composite adhesive material for soft electronics that can safely acquire, transmit, and process complex biological signals with high resolution.

Unmet Need: High performance adhesive, biocompatible soft electronics

Existing soft electronics can interface with nonplanar surfaces, including many types of biological tissue, leading to precise and detailed data collection that can inform medical research and diagnoses. Typical materials for flexible electronics include hydrogels, liquid metal, polymers, and nanomaterials. However, use of these materials is limited by their mechanical robustness, lack of a reliable power source, poor understanding of their long-term biocompatibility, and imperfect adhesion. Without addressing these concerns, soft electronics cannot be applied clinically.

The Technology: Biocompatible material for high resolution biological signal processing

This technology describes a biocompatible composite adhesive material for use in soft electronics. In a single material, the organic mixed‐conducting particulate composite material (MCP) can safely acquire, transmit, and process complex biological signals. The described MCP has demonstrated direct recording of neurophysiological data at high resolution, as well as non-invasively by application to the skin. In addition to anisotropic films, independently addressable transistors, resistors, and pattern-free diodes, this material can also be used for enhancement mode transistors, microarrays for cell culture, and EEG gels.

This technology has been validated in rodents and humans.

Applications:

  • Biocompatible anisotropic conductive films
  • Transistors
  • Resistors
  • Pattern-free and scalable diodes
  • Enhancement mode transistors
  • Microarrays for cell culture
  • EEG gels

Advantages:

  • Enables effective electronic bonding between soft and rigid electronics
  • Permits in vivo recording of neurophysiological data and electrophysical signals at an unprecedented resolution
  • Comprises bioelectronic devices that can safely acquire, transmit, and process complex biological signals
  • Biocompatible
  • Can be applied non-invasively by application to the skin
