MEA Amplifier with Blanking Circuit for Inverse Microscopes

60MEA200/10iR-Ti

Voltage driven stimulation (1 V, electrode 33) on 10 μm TiN electrodes.

The stimulus artifact suppression is slightly impaired by the higher impedance of the smaller
electrodes, but still very good. You see only small artifacts on the channels 21 and 22 with tracks
next to the stimulation electrode 33. Pin 15 of the 60MEA200/10iR-Ti was connected to ground.

60EcoMEA

Voltage driven stimulation (1 V, electrode 33) on 100 μm gold electrodes.

You see only small artifacts on the channels 21 and 22 with tracks next to the stimulation
electrode 33. The blanking performance when using the silver pellet as a ground was
reproducible. However, with the internal reference electrode, there could sometimes be
observed an artifact with very slow kinetics. If you observe such problems, please try out
a silver pellet for grounding the bath.
