a Schematic drawing represents the fabrication of EGOFETs with inkjet printed P3HT. b (top) AFM topographic image of the printed P3HT layer covering the source electrode, channel and drain electrode. (below) Line profile of the AFM image taken at the white line. Inset is a zoom of the AFM image in the channel region. c Drawing of the EGOFET coupled with the hiPSC-CMs layer, where the cell medium acts as an electrolyte for the EGOFET and a gate electrode made of Pt is immersed into the electrolyte. d Top view SEM image of the hiPSC-CMs layer on the EGOFET. e SEM image of the cross-section between the cell and the P3HT layer that forms the channel of the EGOFET. The data are representative of cross sections performed on 5 samples obtained from 2 independent cell cultures.
