FlexMEA36
The FlexMEA36 has 32 recording electrodes plus two internal reference electrodes and two ground
electrodes in a 6 x 6 electrodes grid. The titanium nitride electrodes have a diameter of 30 μm, and
the distance between the electrodes is 300 μm. The polyimide foil is perforated with holes of 30 μm
diameter, ensuring optimal tissue contact.
When using the FlexMEA36 together with a standard 32-channel miniature preamplifier MPA32I,
you need the ADPT-FM-32 adapter to connect the FlexMEA36 to the standard MPA32I. There is no
need for an adapter if you use the FlexMEA36 specified 32-channel miniature preamplifier MPA32I-Flex.
Please read the data sheet FlexMEA36, and the MPA32I (-Flex) manual for more information.
FlexMEA72
The FlexMEA72 has 64 recording electrodes plus four internal reference electrodes and four ground
electrodes in a 8 x 9 electrodes grid. The titanium nitride electrodes have a diameter of 100 μm, and
the distance between the electrodes is either 625 μm or 750 μm. The polyimide foil is perforated with
holes of 100 μm diameter, ensuring optimal tissue contact.
When using the FlexMEA72 together with two standard 32-channel miniature preamplifier MPA32I,
you need the ADPT-FM-72 adapter to connect the FlexMEA72 to two standard MPA32Is. Please read
the data sheet FlexMEA72 or ADPT-FM-72, and the MPA32I manual for more information.
