ref: -0 tags: PEDOT PSS electroplate eletrodeposition neural recording michigan probe stimulation CSC date: 04-27-2017 01:36 gmt revision:1 [0] [head]

PMID-19543541 Poly(3,4-ethylenedioxythiophene) as a micro-neural interface material for electrostimulation

  • 23k on a 177um^2 site.
  • demonstrated in-vitro durable stimulation.
  • Electrodeposited with 6na for 900 seconds per electrode.
    • Which is high -- c.f. 100pA for 600 seconds {1356}
  • Greater CSC and lower impedance / phase than (comparable?) Ir or IrOx plating.

ref: -0 tags: iridium oxide nanotube intracellular recording electroplate MEA date: 02-22-2017 22:41 gmt revision:0 [head]

PMID-24487777 Iridium oxide nanotube electrodes for sensitive and prolonged intracellular measurement of action potentials.

  • Electrodeposition of IrOx "magically" forms 500nm tubes.
  • Holes in Si3N4 / SiO2 were formed via e-beam lithography; underlying Pt wires via liftoff.
  • Showed long (minutes) intracellular access, though it tended to dip with time.
