1.2 Welcome to the Impedance Testing Device MEA-IT
The impedance testing device MEA-IT for microelectrode arrays with 60 electrodes allows an easy
monitoring of MEA electrode impedances. The measurement process is controlled by the software
MEA-IT. On a virtual MEA layout the impedance of each electrode is displayed in an intuitive color
code.
It is possible to save the data after each measurement to a database file and to export the data
in ASCII format . This way you can monitor the development of each single electrode' s impedance
over the entire life span of each microelectrode array.
Based on this information the user can, for example, decide whether a MEA chip can be put to
further use or should be discarded, or if a specific surface treatment or coating has any relevant
influence on the electrode impedance.
