(a) Microelectrode arrays (MEA) with 120 integrated TiN electrodes (30 μm diameter, 200 μm inter-electrode spacing) were used to culture the 2D hESC-CMs. (b) Representative optical image of hESC-CMs on top of MEA. (c) Field potential signals were detected in electrodes which are in touch with the hESC-CMs.
