A new Modular Bionic Interface (MBI) offers wireless, high-bandwidth, bidirectional communication for the nervous system. This fully implantable device advances neuroelectronic interfaces for research and clinical applications.

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Medical Devices

Background:

  • Current neuroelectronic interfaces are tethered, limiting mobility and clinical use.
  • Existing fully implantable systems have design constraints like bulkiness, low bandwidth, or unidirectional communication.

Purpose of the Study:

  • To develop a fully implantable, modular neuroelectronic interface for high-bandwidth, bidirectional neural communication.
  • To enable advanced diagnostics, treatment of neurological dysfunction, and neuroscientific research.

Main Methods:

  • Development of the Modular Bionic Interface (MBI) with an implantable device and a wearable unit.
  • Benchtop validation of recording and stimulation capabilities.
  • Chronic in vivo evaluation in a sheep model over three months.
