Display and data analysis of signals from bioelectronic devices

摘要

The aim of this thesis was to develop the means to display and analyze cellular signals acquired by chip-based extracellular recordings. Two types of chips were used for these measurements: the Multi-Electrode Array (MEA)and the Silicon-based Field-Effect Transistor (FET). The extracellular measurements are based upon an in-house built and programmed low-noiseamplifier system. Using the chips and hardware to amplify the signals, the display process and analysis of the signals could be achieved. "Viewer” was a program performed in “LabVIEW” that enabled the measured channels from a MEA chip to be displayed. In this program, the signals are imported and then each channel is displayed individually on the graphs. Exporting the datawas an important part of the program. Finally, the efficiency of the program was tested.
