Microelectrode arrays (MEAs) are widely used for in vitro and in vivo monitoring of neural and cellular activity. Conventional MEAs rely on electrical sensing to record extracellular potentials, offering high temporal resolution but limited spatial information and sensitivity to electrode impedance, noise, and drift. In recent years, hybrid MEA platforms integrating optical and electrical sensing have emerged, enabling complementary readouts such as electrical spikes, optical signals from voltage- or calcium-sensitive indicators, and local biochemical or optoelectronic responses.
The integration of optical and electrical sensing in a single MEA introduces new challenges in device characterization, including signal crosstalk, noise coupling, spatial resolution mismatch, and calibration consistency across modalities. Systematic characterization is essential for validating performance, understanding limitations, and guiding future device optimization.
This internship aims to perform a comprehensive characterization of a hybrid optical-electrical MEA array ASIC, starting from the ASIC package, PCB design, to the final test platform for future in-vitro experiments.
