4.18 FlexMEA
FlexMEAs are made of flexible polyimide foil, perfect for in vivo and specific in vitro applications.
Only 12 μm "thick" and weighing less than 1 g, the FlexMEA biosensor is very thin and light weight.
The FlexMEAs are available with 32 (64) recording electrodes plus two (four) indifferent reference
electrodes and two (four) ground electrodes in a 6 x 6 (8 x 9) electrodes grid. More layouts can be
provided on request. The flexible base is perforated for a better contact with the surrounding tissue.
The electrodes are from titanium nitride (TiN), contact pads and track material from pure gold.
FlexMEAs are stable at a temperature range from 10 °C to 125 °C and can be autoclaved.
Using FlexMEAs
FlexMEAs are usually connected to a head stage preamplifier that is connected to a filter amplifier
or programmable gain amplifier (see also the ME-System product line of Multi Channel Systems).
Via provided adapters FlexMEAs can be connected to 32-channel miniature preamplifiers MPA32I
from Multi Channel Systems for in vivo experiments. There is no need for an adapter if the FlexMEA
should be connected to the 32-channel miniature preamplifier MPA32I-Flex.
Warning: Do not use an ultrasonic bath for cleaning. The manufacturer recommends sterilization
by rinsing with alcohol.
