Page 6: Welcome To The Mpa32I
FlexMEAs Welcome to the MPA32I The 32-Channel Miniature Preamplifier MPA32I is connected to the microelectrodes for providing the initial tenfold amplification stage. It has additional common ground and reference electrode inputs. The reference electrode is ideally identical to the recording electrodes and placed into a comparable but inactive area or tissue. -

FlexMEAs Setting Up and Connecting the MPA General Setup Recommendations In the following, you find general recommendations for the installation. Important: It is important that the complete setup refers to a single common ground. The reference input has always to be connected. It is recommended to use a reference electrode. However, if you are not using a reference electrode, connect the reference input to ground (GND). -

1. Connect the terminal plug to one miniature preamplifier and the test model probe to the other as shown in the picture (do not mismatch the polarity). If you have only one MPA32I, you can perform the two tests consecutively. -
Page 9: Setting Up Mc_Rack
FlexMEAs Setting up MC_Rack Please refer to the MC_Rack Manual for more information. Start MC_Rack. Open the file MPA32I_NoiseTest.rck on the installation volume (see folder Tutorial).This rack contains the virtual MC_Card instrument as data acquisition device with a continuous raw data display and an Analyzer to measure the peak-to-peak amplitude. - Page 10 FlexMEAs Typical Results Typical results of this test are shown in the following screen shot. The filter amplifier used for this test had a gain of 100 and a bandwidth of 0.5 to 5000 Hz (FA64I-100-0.5-5000). If you use a filter amplifier with a narrower bandwidth, you can generally expect a slightly lower noise level.

FlexMEA36, plastic spacer and adapter (ADPT-FM-32) connected to a 32-channel miniature amplifier MPA32I. The side with no screws is considered the top side of the MPA32I. If the adapter is oriented as shown in the figure, the FlexMEA36 is inserted with the contact pads facing downward. - Page 12 (see also the ME-System product line of Multi Channel Systems MCS GmbH). FlexMEAs can be via adapter connected to a 32-channel miniature preamplifier MPA32I from Multi Channel Systems for in vivo experiments. FlexMEAs are stable at a temperature range from 10 °C to 40 °C.

Page 13: Ecoflexmeas
FlexMEAs EcoFlexMEAs EcoFlexMEAs are made of flexible polyimide material (Kapton), perfect for in vivo and special in vitro applications. Only 50 µm "thick" and weighing less than 10 g, the EcoFlexMEA biosensor is thin and lightweight. EcoFlexMEA36 has 32 gold electrodes plus two internal reference electrodes and two ground electrodes. -

Service and Maintenance Service and Maintenance Cleaning the Connectors Warning: It is recommended to avoid the use of cleaning solutions to avoid corrosion. If a wet cleaning is required, use distilled water. Make sure that only the connectors touch the liquid; do not submerge the miniature preamplifier or the cable. -

Pin Layout Pin Layout Power Supply Supply voltage is applied to the output connector pins 19 and 37. The voltage source should supply a stable noise-free voltage. Do not exceed the maximum voltage. Pin 19: –3 V to –8 V Pin 37: +3 V to +8 V Warning: Do not mismatch the polarity of the power supply. -
Page 20: Test Model Probe
Pin Layout Test Model Probe Test signal IN: You can use the jumper to connect the signal input pin (Signal IN) to ground (standard situation for a noise level test), or you can connect a data source, for example, a sine wave generator to the input (and the ground of the test signal to the signal ground input) to test the signal distribution. -
