PMID-29109247 Highly scalable multichannel mesh electronics for stable chronic brain electrophysiology

  • Key change was the addition of multiple conductor traces per longitudinal mesh line; this allows them to get 64 or 128 channels per mesh without a dramatic increase in modulus.
  • The latitudinal / diagonal lines still displace tissue ...
  • And the injection mechanism, glass pipette, 650um OD, 400um ID, is pretty large, even for 128 channels.
  • Use carbon nanotube ink, custom CNC printer, to connect to FPC.
    • Pretty impressive that they can manipulate ~800nm thick Su-8 film intraop and have it work well!
