Neural Probes using Organic Electrochemical Transistors (OECT)


  • To develop OECT devices for neural activity measurement
  • Implement both OECT and passive devices in the same probe for more precise depth and spatial-neural activity information
  • Implement these devices using 3D printing to allow for unique designs of probes


  • High speed, economical and disposable sensors for neural activity sensing
  • 3D printing of sensors with topography. Active and passive sensors will revolutionize neural sensing
  • Implementation of logic, using the active OECT devices, will allow for feedback control of medication delivery

Key Milestones

  • Demonstrate sensitivity of OECT with different electrolytes
  • 3D printed devices
  • Integrate passive and active devices
  • Functionalize OECT with neuroreceptors for sensing glutamate
  • Determine economic and commercial viability
